Answer:
4600
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4
This indicates the sequence is arithmetic with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = 4 , thus
[tex]S_{50}[/tex] = [tex]\frac{50}{2}[/tex] [ (2 × - 6) + (49 × 4) ]
= 25(- 12 + 196)
= 25 × 184
= 4600
Mr. Young is offered an investment opportunity. Kyra says she will invest his money at a 6% simple interest rate over the next 7 years. Mr. Young decides to invest $3000. How much interest will he have earned when the investment matures? *
Answer:
$126
Step-by-step explanation:
Given that:
Investment is done as per Simple interest.
Principal = $3000
Time for which the investment is to done = 7 years
Rate of interest = 6%
To find:
Interest earned when the investment matures?
Solution:
Formula for Simple Interest :
[tex]Simple\ Interest = \dfrac{PRT}{100}[/tex]
Where [tex]P[/tex] is the principal amount
[tex]R[/tex] is the Rate of Interest
[tex]T[/tex] is the time for which the investment is made
Putting the given values:
[tex]Simple\ Interest = \dfrac{3000\times 6\times 7}{100}\\\Rightarrow Simple\ Interest = \dfrac{12600}{100}\\Simple\ Interest = \$126[/tex]
Therefore, the answer is:
Interest earned is $126.
In which figure is the height of the cylinder half the radius? A cylinder with a height of 2 and diameter of 8. A cylinder with a height of 4 and diameter of 8. A cylinder with a height of 8 and diameter of 8. A cylinder with a height of 16 and diameter of 8.
Answer:
A) A cylinder with a height of 2 and a diameter of 8.
Step-by-step explanation:
The height of the cylinder is half the radius. Therefore.
Height of the cylinder = (half of the radius)/2
Answer choice A) A cylinder with a height of 2 and a diameter of 8.
Note that a diameter is found using the following formula:
d (diameter) = 2r (radius).
First, divide 2 from the diameter to find the radius:
8/2 = 4
Next, divide by 2 again to find the height of the cylinder:
4/2 = 2
In this case, the height of the cylinder is 2, ∴ the choice is correct.

PLEASE HELP WITH #3 i’ll give brainliest
Step-by-step explanation:
Lets begin with this 4x-25=x+14, 3x=39, so x=13, than we plug it in to side NP because that is the most simple one to plug it into to and that side is 27 since the triangle is equilateral all sides are the same so it is 27, 27, 27, for the sides and x=13
A. g(x) = -x2 - 4
B. g(x) = x2 - 4
C. g(x) = x2 + 4
D. g(x) = -4x2
9514 1404 393
Answer:
A. g(x) = -x² - 4
Step-by-step explanation:
The original function f(x) is reflected over the x-axis (-f(x)) and translated down 4 units to become ...
g(x) = -f(x) -4
g(x) = -x² -4 . . . . matches choice A
Mary wants to see if the 2,000 high schoolers at her school like pizza or not. To find out
how many of them like pizza, she goes to a local pizzeria and intends to ask 100 high
schoolers who arrive. She gets tired after asking 15. (7 pts)
a. What is the population? ______________
b. What is the sample? ________________
c. What kind of sampling is she using? ________________
d. Will this poll be biased? If yes how so? If yes, name the type of bias and explain
why this poll has that type of bias.
Answer:
a. 100
b. 15
c. Convenience sampling
d. (i) The poll will be biased because
(ii) The manner of bias of the poll is that the sample chosen from the population are those that are more likely to have the same positive response to the survey question
(iii) Selection bias,
(iv) The reason why the poll has the selection bias is because a subjective sampling method was used
Step-by-step explanation:
The given parameters are;
The number of high schoolers at the school = 2,000
The number of high schoolers at the pizzeria Mary intends to ask = 100
The number of high schoolers she ask = 15
Therefore;
a. The population is the number high schoolers at her school = 100
b. The sample = The number of high schoolers that surveyed = 15
c. The kind of sampling Mary is using is convenience sampling
d. (i) The poll is biased because, the sample chosen from the population are those who already are at the pizzeria where pizza is sold and they are more likely to have the same positive response to the survey question
(ii) The type of sampling bias is Selection bias,
(iii) The reason why the poll has the selection bias is because the sampling was made subjectively by selecting to sample only the high schoolers at the pizzeria, which is the same as the high schoolers that are more certain to like pizza.

Which pair of triangles cannot be proved
congruent?
9
Which pair of triangles cannot be
proved congruent
B.
C.
D.
A
Option B pair of triangles cannot be proved congruent.
What is congruence?Congruence in two or more triangles depends on the measurements of their sides and angles. Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal. They are of the same shape and size.
SSS Criterion for Congruence
SSS criterion stands for Side-Side-Side criterion. Under this criterion, two triangles are congruent if three sides of a triangle are equal to the corresponding sides of the other triangle.
SAS Criterion for Congruence
SAS criterion stands for Side-Angle-Side criterion. Under this criterion, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.
ASA Criterion for Congruence
ASA criterion stands for Angle-Side-Angle criterion. Under the ASA criterion, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.
AAS Criterion for Congruence
AAS criterion stands for Angle-Angle-Side criterion. Under the AAS criterion, two triangles are congruent if any two angles and the non-included side of one triangle are equal to the corresponding angles and the non-included side of the other triangle.
According to the question
Option A :
SAS : A triangle with equal sides and equal angles.
Option C :
SSS : A triangle with equal sides.
Option D :
AAS : A triangle with two equal angles and one equal side.
Option B :
These pair of triangles cannot be proved congruent.
Two triangles with equal corresponding angles may not be congruent to each other because one triangle might be an enlarged copy of the other. Hence, there is no AAA criterion for congruence.

James is building a house on the lot shown below. The dimensions of the lot are (6+x) feet and (6−x) feet. The blue prints show the dimensions of the house to be (2+x) feet and (2−x) feet. The rest of the lot will be his yard.
How large is the yard?
square feet
James is thinking about extending the house by adding 2 feet to the length and 2 feet to the width.
How much area is now left for the yard?
square feet

32 square feet20 square feetStep-by-step explanation:
Given
The dimensions of the lot are (6+x) feet and (6−x) feetThe dimensions of the house to be (2+x) feet and (2−x) feetArea of the yard = Area of the lot - Area of the house
Area of the yard:
(6 + x)(6 - x) - (2 + x)(2 - x) =36 - x² - 4 + x² =32 square feetIf the house is extended, then the area of the yard will change as:
