There are 400 7th graders at your school. You sampled 35 of them and found that 14 students are in advanced math. How many 7th graders can you expect to be in advanced math at your school?
Answer:
160
Step-by-step explanation:
P(advance math | 7th grader) = 14/35 (sample size 35)
Estimated advance math 7th grader in school = 400 * 14/35
= 160
Answer: 160 people can be expected to be in advanced math
Step-by-step explanation:
14 ÷ 35 = 0.4
⇒ what is 40% of 400?
⇒ 0.4 × 400
⇒ 160 people

How would the median change if the number 71 replaced one of the 67's in the set?
71, 67, 67, 17, 69, 84, 21, 87
Question 5 options:
decrease
increase
no change
Answer:
increase
Step-by-step explanation:
Given data is: 71, 67, 67, 17, 69, 84, 21, 87Arranging in ascending order we find: 17, 21, 67, 67, 69, 71, 84, 87 Here N = 8 (Even number)N/2 = 4 and N/2 + 1 = 54th term = 67, 5th term = 69-> median = Sum of 4th and 5th term/2 = (67 + 69)/2 = 132/2 = 66Now, when one of the 67 is replaced by 71, the new data set in ascending order will be: 17, 21, 67, 69, 71, 71, 84, 87Here, 4th term = 69, 5th term = 71New median = (69 + 71)/2 = 140/2 = 70-> new median > initial medianCONCLUSION: Median will increase if the number 71 replaced one of the 67's in the set.

A rectangular image of length 5 cm and width 7 cm is magnified in a studio. On magnification, 1 cm of the image represents 15cm. Find the perimeter of the rectangle in the magnified image.
Answers:
360 cm
180 cm
440 cm
84 cm
Answer:
238 cm
Step-by-step explanation:
so we have a scale factor of 17: 1
originally we had the dimensions: 3cm by 4m
now we have 3*17 by 4*17 = 51 cm by 68 cm
Perimeter = 2*51 + 2*68 = 238 cm
Answer:
360 cm
Step-by-step explanation:
The height of the magnified image is the product of the height of the original image and the scale factor.
h=15(7) cm.
Simplify.
h=105 cm.
The width of the magnified image is the product of the width of the original image and the scale factor.
w=15(5) cm.
Simplify.
w=75 cm.
So, the perimeter is
P=2(75)+2(105) cm.
Simplify.
P=360 cm.
Therefore, the perimeter of the painting is 360 cm.

A rectangle prism with a length of 12.5 cm and a width of 7.5 cm has a
volume of 937.50 cm?. What is the height of the rectangular prism?
Answer:
Height = 10 cm
Step-by-step explanation:
To find the height of the rectangular prism, we need to use the volume equation of rectangular prisms:
V = l * w * h
l = length
w = width
h = height
We know the length (12.5 cm), width (7.5 cm), and the volume (937.50 [tex]cm^{3}[/tex]).
Plug all these into the equation and solve for the height:
937.50 = (12.5)(7.5)h
937.50 = 93.75h Multiply 12.5 by 7.5
10 = h Divide 937.50 by 93.75 to get h.
Therefore, the height of the rectangular prism is 10 cm.
Let's check our answer by plugging all values into the volume equation:
937.50 = (12.5)(7.5)(10)
937.50 = 93.75 (10)
937.50 = 937.50 Both values are equal so 10 is correct!
I hope this helps! Good luck!

What is the length of side AB of parallelogram ABCD?
units
4g - 8
B
q+4
Answer:
8 units
Step-by-step explanation:
» Concepts
Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.
» Application
In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.
» Solving
Step 1: Subtract q from both sides.
[tex]4q-8-q=q+4-q[/tex] [tex]3q-8=4[/tex]Step 2: Add 8 to both sides.
[tex]3q-8+8=4+8[/tex] [tex]3q=12[/tex]Step 3: Divide both sides by 3.
[tex]3q/3 = 12/3[/tex] [tex]q=4[/tex]Step 4: Plug in the value of q for side AB.
[tex]4(4)-8[/tex] [tex]16-8[/tex] [tex]8[/tex]Therefore, the answer is 8 units.

There are a total of 66 students in the
fourth grade at North Elementary
school. Class A has five more
students than Class B. Class C has 2
less students than Class B. How
many students are in class A?
Answer:
A = 26
Step-by-step explanation:
sum of students = classA + classB + classC
let's say classA = A, classB = B, and classC = C
A + B + C = 66
class A has five more students than class B, so A = 5 more than B so A = 5+B
class C has 2 less students than class B, so C = 2 less than class B = B -2, so C = B-2
A + B + C = 66
A = 5+B
C = B-2
substitute 5+B for A and B-2 for C in the first equation to limit this to one variable (B)
(5+B) + B + (B-2) = 66
3B + 3 = 66
subtract 3 from both sides to isolate the variable and its coefficient
3B = 63
divide both sides by 3 to solve for B
B = 21
A = 5 + B = 5 + 21 = 26

Answer:
P(X > 8) = 5/18
P(X mod 5 ≠ 0) = 29/36
Step-by-step explanation:
You want various probabilities related to the sum of two dice.
Greater than 8Please refer to the attached chart of possible outcomes. There are 4 ways to roll a 9, 3 ways to roll a 10, 2 ways to roll 11, and one way to roll 12. That means there are 4+3+2+1 = 10 ways to roll a number greater than 8.
P(X > 8) = 10/36 = 5/18
Not divisible by 5It is easier to count results that are divisible by 5. Then the difference between that number and 36 will be the number of outcomes not divisible by 5.
5 can be rolled 4 ways, and 10 can be rolled 3 ways. A total of 4+3 = 7 of the 36 outcomes are divisible by 5. That means 36 -7 = 29 are not divisible by 5.
P(X not divisible by 5) = 29/36

Hi!
Given these two equations:
[tex]x = y + 8[/tex]
[tex]x + 4 = 2(y + 4)[/tex]
We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:
[tex](y+8)+4=2(y+4)[/tex]
Combine like terms on both sides:
[tex]y+12=2y+8[/tex]
Subtract y from both sides:
[tex]12=y+8[/tex]
Subtract 8 from both sides:
[tex]y=4[/tex]
Now, we can simply plug the y value in to the first equation, and solve for x:
[tex]x=4+8[/tex]
Simplify:
[tex]x=12[/tex]
Therefore, x is equal to 12 and y is equal to 4.Learn more about the substitution (and also elimination!) method here:
