Answer:
7y+42
Step-by-step explanation:
If I am doing this correctly (so take it with a grain of salt from just waking up) you would multilpy 7 with the expressions in the ( )
So it would be 7*y= 7y
Then 7*6= 42
So it would be 7y+42 I think
Sorry if it is incorrect/ doesn't answer your question. Good luck!
Answer:

The characteristics of the given points are observed during the
geometric construction processes.
Responses:
Step 1: The point O is the center because it is equidistant from the three points
Step 2: PQ = PR = QR, therefore, ΔPQR is an equilateral triangle
b) The ratio of a leg to the hypotenuse side of ΔACF is 0.5, therefore, ΔACF is a 30°– 60°–90° triangle
c) The points of intersection of the diameter and a perpendicular bisector with the circumference of the circle are the vertices an inscribed square of the circle
Which process of geometric construction determines the characteristics of the given points?
Step 1: How to know that the point O is the center of the circle is as follows;
The perpendicular bisectors constructed are the locus of points
equidistant from the both points D and E and also the perpendicular
bisector gives the locus of points equidistant from points E and F
Therefore;
OE = OE, by reflexive property
OE is also equal to OF and OD by definition of the point O being on both
perpendicular bisectors.
Given that OE = OF = OD, we have that the point O is the center of a
circle with radius, OE = OF = OD passing through the points E, F, and D
Therefore;
The point O is the center because it is equidistant from the three pointsStep 2: Given that the center of the circles are the points P and Q, we have;
PQ = The radial length of the two circles
Similarly
PR and QR are radial lengths of circle P and Q respectively
Therefore;
PQ = PR = QR
Which gives;
The lengths of the sides of ΔPQR are equal and ΔPQR is an equilateral triangleb) FC is the diameter of circle M
Therefore;
∠ACF is 90° and ΔACF is a right triangle
The ratio of the a leg to the hypotenuse side of a 30°– 60°–90° triangle is 0.5
Length of FA = FM = MC
[tex]\dfrac{FA}{FC} = \dfrac{FA}{FM + FC} = \dfrac{FA}{FA + FA} = \dfrac{FA}{2 \times FA} = \dfrac{1}{2} = \mathbf{0.5}[/tex]
Given that the ratio of a leg to the hypotenuse side of ΔACF is 0.5, ΔACF is a 30°– 60°–90° trianglec) The steps that can be used to locate the vertices of a square inscribed
in a circle are;
Draw a diameter of the circle (passing through the center)Construct the perpendicular bisector of the diameter, and extend it to intersect with the circle at the possible two pointsThe points of intersection of the diameter and the perpendicular bisector with the circumference of the circle are the location of the vertices an inscribed square of the circle

The angles of a triangle are 5x°,7x° and 60° find the value of x
Answer:
x= 10
Step-by-step explanation:
We can use the fact that the sum of all angles in a triangle is 180°.
5x +7x +60 = 180
Solve for x, because we have 1 equation with 1 unknown
5x +7x +60 = 180, combine like terms
12x + 60 = 180. subtract 60 from both sides of the equation
12x + 60 -60 = 180 -60, combine like terms
12x = 120, divide both sides by 12
x = 10

What is the simplest form of StartRoot 3,025 EndRoot?
Answer:
55
Step-by-step explanation:
Value of √3025 by Long Division Method
Forming pairs: 30 and 25
Find a number Y (5) such that whose square is <= 30. Now divide 30 by 5 with the quotient as 5.
Bring down the next pair 25, to the right of the remainder 5. The new dividend is now 525.
Add the last digit of the quotient (5) to the divisor (5) i.e. 5 + 5 = 10. To the right of 10, find a digit Z (which is 5) such that 10Z × Z <= 525. After finding Z, together 10 and Z (5) form a new divisor 105 for the new dividend 525.
Divide 525 by 105 with the quotient as 5, giving the remainder = 525 - 105 × 5 = 525 - 525 = 0.
We stop the process since the remainder is now 0 and there are no more digits that can be brought down.
Therefore, the square root of 3025 by the long division method is 55.

Anna selects a positive multiple of 4 that is less than forty, and Becky selects a positive multiple of 3 that is less than sixty. What is the probability that they pick the same number?
The probability that both pick the same number is p = 0.018
How to find the probability?
First, we need to count the number of options that each kid has.
There are 9 multiples of 4 less than 40.There are 19 multiples of 3 less than 60.Such that the common numbers in these two lists are:
4*3 = 124*6 = 244*9 = 36.We need to find the probability that both kids select one of these 3 numbers at the same time.
Then, Anna must select any of these 3 out of the 9 possibilities, so the probability for Anna is:
P = 3/9.
Then, Becky must select the same one than Anna, so there is only one number out of the 19 possibilities that she has, then the probability is:
Q = 1/19
The joint probability is given by the product between these 2 numbers, it is:
p = (3/9)*(1/19) = 0.018

The vertex of the parabolaThe vertex of the parabola of a quadratic function is given by;
[tex]\rm \text{The vertex of the parabola}= \dfrac{-b}{2a}[/tex]
Expand the function then solve;
[tex]\rm f(x)=-(x +8)(x-14)\\\\f(x)=-(x(x-14)+8(x-14))\\\\f(x)=-(x^2-14x+8x-112)\\\\f(x)= -x^2+6x+112[/tex]

[tex]\rm \text{The vertex of the parabola}= \dfrac{-b}{2a}\\\\\rm \text{The vertex of the parabola}= \dfrac{-6}{2\times -1}\\\\\rm \text{The vertex of the parabola}= 3[/tex]
Substitute x = 3 into f(x) for corresponding value of y
f(3) = - (3)² + 6(3) + 112 = - 9 + 18 + 112 = 121
Hence, the y-value of the vertex of the function is 121.

An environmental group conducted a study to determine whether crows in a certain region were ingesting food containing unhealthy levels of lead. A biologist classified lead levels greater than 6.0 parts per million (ppm) as unhealthy. The lead levels of a random sample of 23 crows in the region were measured and recorded. The mean lead level of the 23 crows in the sample was 4.90 ppm and the standard deviation was 1.12 ppm.
a) Construct and interpret a 90 percent confidence interval for the mean lead level of crows in the region.
b) A previous study of crows showed that the population standard deviation was at 2.6 ppm. What minimum sample size would be required to construct a 90 percent confidence interval to have a margin of error within 0.03?
Part A
Given info:
xbar = sample mean = 4.90 ppms = sample standard deviation = 1.12 ppmn = 23 = sample sizeBecause n > 30 is not true, and we don't know the population standard deviation (sigma), this means we must use a T distribution.
The degrees of freedom here are n-1 = 23-1 = 22.
At 90% confidence and the degrees of freedom mentioned, the t critical value is roughly t = 1.717
Use a T distribution table or calculator to determine this. If you don't have a calculator for the task, then you can search out "inverse T calculator" and there are tons of free options to pick from.
The margin of error E is
E = t*s/sqrt(n)
E = 1.717*1.12/sqrt(23)
E = 0.400982
This is approximate and accurate to 6 decimal places.
The confidence interval is going to be xbar plus or minus that E value
L = lower bound = xbar - E = 4.90 - 0.400982 = 4.499018 = 4.50
U = upper bound = xbar + E = 4.90 + 0.400982 = 5.300982 = 5.30
The confidence interval in the format of (L, U) is (4.50, 5.30)
You could also express it as the format L < mu < U and it would be 4.50 < mu < 5.30; however, I'll stick to the first method.
Answer: (4.50, 5.30)=====================================================
Part B
Since we know sigma = 2.6 is the population standard deviation, we can use a Z distribution now.
At 90% confidence, the z critical value is roughly 1.645; use a table or calculator to determine this.
[tex]n = \left(\frac{z*\sigma}{E}\right)^2\\\\n \approx \left(\frac{1.645*2.6}{0.03}\right)^2\\\\n \approx 20325.254444 \\\\[/tex]
Round this up to the nearest integer to get 20326. For min sample size problems, always round up.
Answer: 20326Triangle ABC has perimeter 22 cm.
AB = 8 cm
BC = 5 cm
By calculation, deduce whether triangle ABC is a right-angled triangle.
Answer:
No, its not a right angle triangle. check for explanation below ↓
In order to figure whether ABC is a right-angled triangle.
First find the missing side:
22 - 8 - 5
9 cm
so the sides are 5 cm, 8 cm, 9 cm
using the rule:
short side² + short side² = biggest side²
5² + 8² = 9²
25 + 64 = 81
89 = 81
Thus found ABC is not a right-angled triangle.
[tex]AC = 22 - (8+5) = 22 - 13 = 9[/tex]
[tex]9^2 + 13^2 = 81 +169 = 250[/tex]
[tex]22^2 = 484[/tex]
So no, ABC is NOT a right triangle because the pythagorean thoerem fails

A customer will borrow $12,000 to buy a car. Which loan option would allow
the customer to pay the least amount of interest?
A 4-year loan with a 5.2% annual simple interest rate
A 5-year loan with a 4.2% annual simple interest rate
A 6-year loan with a 4.7% annual simple interest rate
O
A 3-year loan with an 8.4% annual simple interest rate
Answer:
number one is the best one
The loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.
Calculation of loan with least simple interest rateFormula for simple interest = P ×T × R/100
P = Principal amount borrowed ($12,000)
T = Time in various years given
R = Rate of simple interest generated
To determine which loan option that would allow the customer to pay the least amount of interest, the simple interest of each option is calculated below
Simple interest of a 4 years loan = 12000×4×5.2/100
= $2,496
Simple interest of a 5 years loan= 12000×5×4.2/100
= $2,520
Simple interest of a 6 years loan= 12000×6×4.7/100
= $3,384
Simple interest of a 5 years loan= 12000×3×8.4/100
= $ 18,144
Therefore, the loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.

The probability of rain in April is 40%. If there are 30 days in April, how many days would you expect rain?
Answer:
12 days
Step-by-step explanation:
10% = 3 (30/10)
To find 40%, we can just times the above by 4.
3*4=12 therefore 12 days can expect rain.
Hope this helps!
The number of days you would expect rain is 12 days in April.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Probability of rain in april= 40%
Days=30
Now,
To answer this question, you need to use the formula for expected value:
Expected value = probability × number of trials
In this case, the probability of rain is 40%, which can be written as 0.4 in decimal form. The number of trials is the number of days in April, which is 30.
Plugging these values into the formula, we get:
Expected value = 0.4 × 30 = 12
Therefore, by probability the answer will be 12 days in April.
