Answer:
88 misses / 66 makes
Step-by-step explanation:
Mark's ratio consists of 4+3=7 total shots.
154 shots would be 22*7 since the ratio would remain proportional
Therefore, (22*4)/(22*3)=88/66 will be the ratio of free-throw misses to makes. This means Mark will make 88 misses and 66 makes if he does 154 total free throws.

Step-by-step explanation:
Answer:
9pi meters^2
Step-by-step explanation:
The area of a circle is pi * r^2. Basically, pi is simplified to 3.14 but for an exact answer, you'd leave it as a symbol. the "r" stands for the radius which is given(3). we square 3 to get 9. so the answer should be 9 pi or about 28.26.

Eight people go to a movie. Adult tickets cost $15 and children's tickets cost $8
The total cost was $85. Write an equation and use it to help you find the numbers of
adults and children who went to the movie.
Answer: number of adults = 3, number of children = 5
Step-by-step explanation:
let the number of adults be x, and the number of children be y.
x + y = 8 , 15x + 8y = 85
1st equation x 8 = 8x + 8y = 64
[tex]8x+8y-15x-8y = 64 - 85\\-7x = -21\\x=3[/tex]
substitute x=3
[tex]3+y=8\\y=5[/tex]
If you place a 29-foot ladder against the top of a building and the bottom of the ladder is 24 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answer:
16.3
Step-by-step explanation:
The height of the building to the nearest tenth is 16. 3 ft
The situation forms a right triangle.
Properties of a right triangle:One of its angles is 90 degreesThe sides can can be found using Pythagoras theorem.The length of the ladder is the hypotenuse of the triangle formed.
The distance from the foot of the ladder to the bottom of the building is the adjacent sides.
Therefore,
c² = a² + b²
where
c = hypotenuse
a and b are the other two legs.
b² = 29² - 24²
b² = 841 - 576
b = √265
b = 16.2788205961
b = 16.3 ft

o yes
no
Answer:
x = √72 and yes, it forms a Pythagorean triple
Step-by-step explanation:
a^2 + b^2 = c^2,
3 is a, x is b, anf 9 is c
3^2 + x^2 = 9^2
9 + x^2 = 81
Subtract 9 from both sides
x^2 = 72
x = √72
a Pythagorean triple is a^2 + b^2 = c^2, and this has it
Answer:
X = 9.4
Step-by-step explanation:
Pythagorean Theorem:
Formula: a² + b² = c²
9 x 9 = 81 3 x 3 = 9 81 + 9 = 90 √90 = 9.48 (Rounded 9.5)- A Pythagorean triple consists of any three positive integers.

Please use the following scenario for this question and the following 4 questions. The national academy of sciences reported in a 1997 study that 40% of research in mathematics is published by US authors. The math chairperson of a university wishes to test the claim that this percentage is no longer 40%. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 130 recent articles published by reputable math research journals and finds that 62 of these articles have US authors. Does this evidence support the math chairperson's claim that the percentage is no longer 40%
Answer:
The evidence does not support the math chairperson's claim that the percentage is no longer 40%
Step-by-step explanation:
The known population percentage of research in mathematics published by US authors = 40%
The proportion, p = 0.40
Therefore, q = 1 - p = 1 - 0.4 = 0.6
The number of articles in the sample = 130
The number of articles by US authors in the sample = 62
Therefore, the proportion of US authors in the sample, [tex]\hat p[/tex] = (62/130) × 100 =
[tex]0.4\overline{769230}[/tex]
∴ The percentage of US authors in the sample ≈ 47.7%
The null hypothesis, H₀; p = 0.4
The alternative hypothesis, Hₐ; p ≠ 0.4
The z-test is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p\cdot q}{n}}}[/tex]
[tex]z=\dfrac{0.477-0.40}{\sqrt{\dfrac{0.4\times 0.6}{130}}} \approx 1.792[/tex]
The p-value P(Z > 1.79) = 2 × (1 - 0.96327) = 0.07346
Therefore, given that the p-value is larger than 0.05 there is significant evidence in favor of the null hypothesis and we reject the alternative hypothesis
Therefore, also, there is not enough statistical evidence to support the math chairperson's claim that the percentage is no longer 40%.
23% of a number is 147.2.
What is the original number?
the answer is 640.
if you take 640 and multiply it by .23 (because of 23%), you get 147.2 which is exactly what you are looking for.
Hope this helps! :)

The figure shows a person estimating the height of a tree by looking at the
top of the tree with a mirror. Assuming that both the person and the tree form
right angles with the ground, which of the following proportions can be used
to estimate the height of the tree?
Answer:
The proportion that can be used to estimate the height of the tree is option;
A. [tex]\dfrac{h}{12} = \dfrac{6}{5}[/tex]
Step-by-step explanation:
The given parameters in the question are;
The medium through which the person looks at the top of the tree = A mirror
The angle formed by the person and the tree with the ground = Right angles = 90°
The distance of the person from the mirror, d₁ = 5 ft.
The height of the person, h₁ = 6 ft.
The distance of the tree from the mirror, d₂ = 12 ft.
The angle formed by the incident light from the tree on the mirror, θ₁ = The angle of the reflected light from the mirror to the person, θ₂
Let 'A', 'B', 'M', 'T', and 'R' represent the location of the point at the top of the person's head, the location of the point at the person's feet, the location of the mirror, the location of the top of the tree and the location of the root collar of the tree, we have;
TR in ΔMRT = The height of the tree = h, and right triangles ΔABM and ΔMRT are similar
The corresponding legs are;
The height of the person and the height of the tree, which are AB = 6 ft. and TR = h, respectively
The distances of the person and the tree from the mirror, which are BM = 5 ft. and MR = 12 ft. respectively
∴ The angle formed by the incident light from the tree on the mirror, θ₁ = ∠TMR
The angle of the reflected light from the mirror to the person, θ₂ = ∠AMB
Given that θ₁ = θ₂, we have;
tan(θ₁) = tan(θ₂)
∴ tan(∠TMR) = tan(∠AMB)
[tex]tan\angle X = \dfrac{Opposite \ leg \ length \ to \ reference \ angle}{Adjacent \ leg \ length \ to \ reference \ angle}[/tex]
[tex]tan(\angle TMR) = \dfrac{TR}{MR} = \dfrac{h}{12}[/tex]
[tex]tan(\angle AMB) = \dfrac{AB}{BM} = \dfrac{6}{5}[/tex]
From tan(∠TMR) = tan(∠AMB), we have;
[tex]\dfrac{h}{12} = \dfrac{6}{5}[/tex]
[tex]\therefore h = \dfrac{6 \, ft.}{5 \, ft.} \times 12 \, ft. = 14.4 \, ft.[/tex]
The height of the tree, h = 14.4 ft.
Therefore, from the proportion [tex]\dfrac{h}{12} = \dfrac{6}{5}[/tex] the height of the tree can be estimated.
