Ms. Lopez buys 12 packages of socks for her sons. Each package contains 5 pairs of socks. If she gives one son 32 pairs, how much does she give the other son?
Answer: 28 pairs
Step-by-step explanation:
12 times 5 is 60, so she has 60 pairs in total. She gives 32 pairs to one son, so 60-32 is 28. The other son receives 28 pairs of socks.

Hi!
We are given the information found in the picture below.
Note: The directions aren't correct, but the triangle works for this problem.
The "direct path" is the hypotenuse of this triangle.
To find this, we use the Pythagorean Theorem, where [tex]a[/tex] and [tex]b[/tex] are 2 legs of the triangle, and [tex]c[/tex] is the hypotenuse, aka the longest side of any triangle:
[tex]a^2+b^2=c^2[/tex]
We know [tex]a[/tex] and [tex]b[/tex] and want [tex]c[/tex]
[tex]4^2+5^2=c^2[/tex]
[tex]16+25=c^2[/tex]
[tex]41=c^2[/tex]
Therefore, [tex]c[/tex] is approximately [tex]6.403[/tex]

Which of the following describes the graph shown?
Answer:
third from top down
Step-by-step explanation:
We can think of f(x) as y
y = 3 if x ≥ 3, y coordinate is always 3, while x coordinate starts at 3 inclusive and goes on toward +∞
y = -1 if x ≤ -1, y coordinate is always -1, while x coordinate starts at -1 inclusive and goes on toward - ∞

what is 3+6/2
4+4/2
4+4x4
4x4x4
Answer:
it is 4+4/2
Step-by-step explanation:
you use pemdas which is
parenthesis, exponents, multiplication, division, addition, and subtraction.
now you go from left to right so if you see division before multiplication then you will do division first because addition and subtraction and multiplication and division are equal so multiplication is not more important than division and addition is not more impirtant than subtraction.
so basically you do 4/2 which is 2
and
4+2=6

9 bags sorry for the other answer
she has 7 boxes at home, then she goes and buys 6 more from the store, now she has 7 + 6 = 13 boxes of chips, each box of chip has 13 bags, so the total amount of potato chips I guess is 13 * 13 = 169 bags total.
So she split it even among her 9 students, so how many times does 9 go into 169? 169 ÷ 9, has a quotient of 18 with a remainder of 7.
18 * 9 = 162, plus 7 = 169, which is the total amount of potato chips bags.

Use the graph to solve the system of equations.
Answer:
( -2 , 1 )
Step-by-step explanation:
Add the 2 equations downwards.
( -x+4y=6 ) + ( 2x-y=-5 )...consider the sign of each term.
= x + 3y = 1
Put -2 in x because that's where the graph above shows an intersection of the 2 equations.
-2 + 3y = 1
3y = 3
y = 1.
( x , y) = ( -2 , 1 )

Factoring the number is just listing all the whole numbers it can be divided by, and in this case it includes the variable. 16a is dividable by 1, 2, 4, 8, 16, and a; since 16a / a = 16. Apply this to 18b, and 1, 2, 3, 6, 9, 18, and b.

Write the equation of a line that passes through the point (-8,4) and is parallel to the line y=-5x+3.
Answer: y=-5x-36
Step-by-step explanation:
In order for two lines to be parallel they need to have the same slope. so the slope (m) of the new line needs to be -5.
slope(m) =-5
and the point (-8,4) is given to us. we can create a new equation for a line using the point slope formula because we have a slope (m=-5) and a point (-8,4)
point slope formula: y-y1=m(x-x1)
y-4=-5(x--8)
simplify and pay attention to negative signs
y-4=-5(x+8)
y-4=-5x-40
y=-5x-36

Which is greater 2/4 or 2/3
Answer: I would say 2/3
Step-by-step explanation:
U can see that 2/3 is almost a whole (3/3) while 2/4 is just halfway there
Or
you can turn 2/4 and 2/3 to a decimal
2/4 = 0.5
2/3 = 0.666
0.5 < 0.666
2/4 < 2/3
hope this helps
Answer:
2/3
Step-by-step explanation:
2/3 is greater because 2/4 = 1/2 and 2/3 is a bit greater than 1/2.
A roller coaster at XTRA Fun Rides goes into an underground tunnel during the first descent of the
ride. The coaster enters the tunnel three seconds after the first descent starts and stays in the
tunnel for a total of 2 seconds. The roller coaster Is 40 feet above ground
one second after the
Initial drop. The graph below represents the height of the roller coaster versus the time passed
since the initial drop.
Answer:
y-intercept: (0, 75) ⇒ y = 75
x-intercepts: (3, 0) and (5, 0) ⇒ x = 3 and x = 5
vertex: (4, -5)
Step-by-step explanation:
Let the x-axis be the ground (when y = 0). Therefore underground when y < 0 and overground when y > 0
The function is a quadratic: f(x) = ax² + bx + c
If the coaster enters the tunnel three seconds after the first descent starts and stays in the tunnel for a total of 2 seconds, then y = 0 when x = 3 and x = 5
Also, when x = 1, y = 40
f(3) = 0Solve 2 equations simultaneously:
9a + 3b + c = 025a + 5b + c = 0a + b + c = 40⇒ a = 5 b = -40 c = 75
⇒ f(x) = 5x² - 40x + 75
y-intercept
when x = 0
⇒ f(0) = 5(0²) - 40(0) + 75 = 75
⇒ y-intercept = (0, 75)
x-intercepts
x = 3 and x = 5
Vertex
If the x-intercepts are when x = 3 and x = 5, then vertex is when x = 4
⇒ f(4) = 5(4²) - 40(4) + 75 = -5
⇒ vertex = (4, -5)

what is the value of x in units
Answer:
x = 25
Step-by-step explanation:
ΔBDR ~ ΔQDC
so
(24 + 40)/(15 + x) = 40/x
or
(24 + 40)/40 = (15 + x)/x
24/40 + 40/40 = 15/x + x/x
3/5 + 1 = 15/x + 1
3/5 = 15/x
Cross multiply,
3x = 15*5 = 75
x = 75/3 = 25
(1) The scores ou an aptitude test for finger dexterity are uonually distributed with meau 250 and
standard deviation 65.
a) What is the probability that a person selected at random will score between 240 and 270 on the
test?
b) Test is given to a random sample of seven people. What is the probability that the mean score,
I for the sample will be between 240 and 270?
Using the normal distribution and the central limit theorem, it is found that there is a:
a) 0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.
b) 0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
The mean is of [tex]\mu = 250[/tex].The standard deviation is of [tex]\sigma = 65[/tex].Item a:
The probability is the p-value of Z when X = 270 subtracted by the p-value of Z when X = 240, hence:
X = 270:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{270 - 250}{65}[/tex]
[tex]Z = 0.31[/tex]
[tex]Z = 0.31[/tex] has a p-value of 0.6217.
X = 240:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{240 - 250}{65}[/tex]
[tex]Z = -0.15[/tex]
[tex]Z = -0.15[/tex] has a p-value of 0.4404.
0.6217 - 0.4404 = 0.1813.
0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.
Item b:
We have a sample of 7, hence:
[tex]n = 7, s = \frac{65}{\sqrt{7}} = 24.57[/tex]
X = 270:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{270 - 250}{24.57}[/tex]
[tex]Z = 0.81[/tex]
[tex]Z = 0.81[/tex] has a p-value of 0.7910.
X = 240:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{240 - 250}{24.57}[/tex]
[tex]Z = -0.41[/tex]
[tex]Z = -0.41[/tex] has a p-value of 0.3409.
0.7910 - 0.3409 = 0.4501.
0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.
