Answers
Answer:
x = 4, y = 2
Step-by-step explanation:
3x - 2y = 8
-2y = -3x + 8
y = 3/2x - 4
2x + 4(3/2x - 4) = 16
2x + 6x - 16 = 16
8x = 32
x = 4
3(4) - 2y = 8
12 - 2y = 8
-2y = -4
y = 2

Mrs. Alberts has two seventh grade math classes this year. They took their final exam, and Mrs. Alberts just finished grading them. She made a box-and-whisker plot for each class in order to compare their results.
Analyze the box-and-whisker plots from above and then select the following comparative inferences that are true. Select all that apply.
1. The interquartile range of Class A is about twice as large as the interquartile range of Class B.
2. There is very little overlap in the two data sets.
3. The median of Class A is about 5 points higher than the median of Class B.
4. The range of Class B is about 12 points less than the range of Class A.
5. A student in Class B had the highest score of both classes.

The roof of a turret is shaped like a cone. The base of the cone is 30 m across and the height is 8 m. The slant height of the roof, which is unknown, is the hypotenuse of the right triangle formed with the radius and the height of the cone.
(a) Sketch the roof of the turret. Label all lengths, using x as the unknown.
(b) What is the slant height of the roof? Answer:
Answers
Answer:
Solution given:
base=diameter [d]=30m
radius [r]=d/2=15m
height [H]=8m
slant height [l]=xm
we have
∆ ABC is a right angled triangle
base[b]=r
perpendicular [p]=H
hypotenuse [h]=x
by using Pythagoras law
h²=p²+b²
x²=H²+r²
x²=8²+15²
x=√289
x=17m
the slant height of the roof is 17m.

The -1/2x is the slope or the rise/rub
The -3 is the y-intercept
So start by placing the y-intercept (0,-3), then from there place the slope (-1/2), since the slope is negative instead of going up one and two to the left you are going to go down one and two to the right, then place a point and repeat. After repeating 2-3 times you should be able to connect the points in order to make a line. If you have any questions let me know!

Which system of equations has infinitely many solutions?
A

B

−4x+2y=−8
C
4x+2y=8
4x+2y=10
D
4x+2y=8
−4x−2y=−10
Answers
Answer: B.
[tex]4x - 2y = 8\\-4x + 2y = -8[/tex]
Step-by-step explanation:
Let's solve your system by elimination.
4x−2y=8;−2x+2y=6
Add these equations to eliminate y:
4x-2y=8
-2x+2y=6
2x=14
Substitute 7 for x in 4x−2y=8:
(4)(7)−2y=8
−2y+28=8 (Simplify both sides of the equation)
−2y+28+−28=8+−28 (Add -28 to both sides)
−2y=−20
−2y/−2=−20/−2 (Divide both sides by -2)
y=10

it has 2 congruent sizes, no right angles and seems two big to be acute
Answer:
obtuse isosceles
Step-by-step explanation:
An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?
Answers
Answer:
40 waves
Step-by-step explanation:
Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%
Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40
Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.What is the value of the expression -9 x 2.2?

The probability of the number of defective circuit boards in a shipment is given in the tables for two different companies. Company A A 5-column table has 2 labeled rows. The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.21, 0.30, 0.41, 0.08. Company B A 5-column table has 2 labeled rows. The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.18, 0.32, 0.28, 0.22. What is the expected number of defective circuit boards for company A? What is the expected number of defective circuit boards for company B? Which company should be chosen for purchasing circuit boards? Explain.

The weighted average is a generalization of the expected value. The company that should be chosen for purchasing circuit boards is Company A.
What is the expected value?The weighted average is a generalization of the expected value. The expected value is the arithmetic mean of a large number of independently chosen random variable outcomes.
A.) The expected number of defective circuit boards for company A is,
Expected number = (0.21×0) + (0.30×1) + (0.41×2) + (0.08×3) = 1.36
B.) The expected number of defective circuit boards for company B is,
Expected number = (0.18×0) + (0.32×1) + (0.28×2) + (0.22×3) = 1.54
C.) Since the expected number of defective circuit boards for Company A is less, therefore, the company that should be chosen for purchasing circuit boards is Company A.
