Explanation:
The problem mentions "see the figure" but the figure above the text does not match the problem itself. I'm assuming the figure is shown below the given text, which unfortunately, is cut off from the screenshot.
The good news is that I think I can recreate what's being described. See the image below.
The things to focus on are the left-most and right-most triangles. We'll use the tangent ratio to help determine x and y. Afterward, compute x+y to get the total distance between the buildings.
First we have,
tan(angle) = opposite/adjacent
tan(32) = 500/x
x*tan(32) = 500
x = 500/tan(32)
x = 800.1673
Using similar steps, you should find that,
y = 500/tan(23)
y = 1177.9262
Therefore,
x+y = 800.1673+1177.9262
x+y = 1978.0935 feet is the approximate distance between Soldier Field and Adler Planetarium.
This is of course assuming that the diagram shown below matches with what your textbook has. Round the answer however you need.
Suppose that x is a differentiable function of t and that y=5x+4, then
dy/dt=
Use either dx/dt or x'(t) in your answer.
If dx/dt=6 when x=-2, then
dy/dt|x=-2=
Answer:
dy/dt = 30
Step-by-step explanation:
y = 5x + 4
dy/dx = 5
dy/dt = dy/dx * dx/dt = 5 * 6 = 30
If you know the ratio of 2 numbers and you want to find out what happens to the ratio if you increase one number, which operation should you use?
A) addition
B) division
C) multiplication
D) subtraction
Answer:
B) division
C) multiplication
Step-by-step explanation:
Ratios give the relation between two quantities.
For example, if two quantities A and B have a ratio of 1:3, it means that:
- for every quantity of A, B has three times more (multiply)
- for every quantity of B, A has three times less. (divide)

Past insurance company audits have found that 2 percent of dependents claimed on an employee’s health insurance actually are ineligible for health benefits. An auditor examines a random sample of 7 claimed dependents. (a) What is the probability that all are eligible? (b) That at least one is ineligible?
Using the binomial distribution, it is found that the probabilities are given by:
a) 0.8681 = 86.81%.
b) 0.1319 = 13.19%.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, we have that:
98% of the employees are eligible, hence p = 0.98.A sample of 7 was taken, hence n = 7.Item a:
The probability is P(X = 7), hence:
P(X = 7) = 0.98^7 = 0.8681 = 86.81%.
Item b:
The probability is:
P(X < 7) = 1 - P(X = 7) = 1 - 0.8681 = 0.1319 = 13.19%.

A new anxiety medication has been manufactured and a study is being conducted to determine whether its effectiveness depends on dose. When 40 milligrams of the medication was administered to a simple random sample (SRS) of 60 patients, 21 of them demonstrated lower stress levels. When 75 milligrams of the medication was administrated to another SRS of 85 patients, 34 of them demonstrated lower stress levels. Which of the following test statistics is an appropriate hypothesis test?
The test statistics is used to determine if the anxiety medication can happen under a null hypothesis
The test statistics that is an appropriate hypothesis test is [tex]z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}[/tex]
How to determine the test statistic40 milligrams of medication
Patients = 60
Lower stress level patients = 21
The mean of this medication is:
[tex]\bar x = \frac{x}{n}[/tex]
So, we have:
[tex]\bar x_1 = \frac{21}{60}[/tex]
[tex]\bar x_1 = 0.35[/tex]
75 milligrams of medication
Patients = 85
Lower stress level patients = 34
The mean of this medication is:
[tex]\bar x = \frac{x}{n}[/tex]
So, we have:
[tex]\bar x_2 = \frac{34}{85}[/tex]
[tex]\bar x_2 =0.4[/tex]
The test statistic is then calculated as:
[tex]z =\frac{\bar x_1 - \bar x_2}{\sqrt{\frac{\bar x_1(1 - \bar x_1)}{n_1} + \frac{\bar x_2(1 - \bar x_2)}{n_2}}}[/tex]
The equation becomes
[tex]z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}[/tex]
Hence, the test statistics that is an appropriate hypothesis test is [tex]z =\frac{0.35 - 0.40}{\sqrt{\frac{0.35(1 - 0.35)}{60} + \frac{0.40(1 - 0.40)}{85}}}[/tex]

Solve the inequality - 6 x > 42
what happens to the inequality sign when you divide by a negative number
Answer:
the inequality sign changes when dividing by a negative number
Answer:
x < -7
Step-by-step explanation:
-6x > 42
First you want to divide off -6 to isolate x
[tex]\frac{-6x}{-6}[/tex] = [tex]\frac{42}{-6}[/tex]
keeping in mind what you do to one side of the equation you have to do to the other side.
Whenever you divide with a negative number the inequality sign flips from < to > and vice versa.
after you divide off the -6 your left with x < [tex]\frac{42}{-6}[/tex] which equals -7.

A teacher needs to purchase notebooks and pencils for her students. Notebooks come in packages of 6 and pencils in packages of 10. The table shows the cost of the items. What is the least amount of money the teacher can spend and have the same number of notebooks and pencils.
Answer:
$31.00
Step-by-step explanation:
Given:
1 package = 6 notebooks = $5.001 package = 10 pencils = $2.00We need to find the LCM of 6 and 10:
Multiples of 6: 6, 12, 18, 24, 30
Multiples of 10: 10, 20, 30
Therefore, the LCM = 30
So the least number of notebooks and pencils the teacher can buy to have the same numbers of each is 30.
⇒ 30 ÷ 6 = 5 packages of notebooks
⇒ 30 ÷ 10 = 3 packages of pencils
5 packages of notebooks = 5 × $5.00 = $25.00
3 packages of pencils = 3 × $2.00 = $6.00
Therefore, the least amount of money the teacher can spend to have the same number of notebooks and pencils (30 each) is:
⇒ $25.00 + $6.00 = $31.00
The least amount of money the teacher can spend to have the same number of notebooks and pencils is $31.00.
To find the least amount of money the teacher can spend and have the same number of notebooks and pencils, we need to determine the least common multiple (LCM) of the quantities in the packages.
Notebooks come in packages of 6, and pencils come in packages of 10. The LCM of 6 and 10 is 30.
To achieve the same number of notebooks and pencils, the teacher could buy:
5 notebook packages (5 * 6 = 30 notebooks)
3 pencil packages (3 * 10 = 30 pencils)
Now, let's calculate the cost:
Cost of notebook packages = 5 * $5.00 = $25.00
Cost of pencil packages = 3 * $2.00 = $6.00
Total cost = $25.00 + $6.00 = $31.00
So, the least amount of money the teacher can spend to have the same number of notebooks and pencils is $31.00.

4(2)-5(2)(5)
What’s the answer ??
Answer:
-42
Step-by-step explanation:
by PEMDAS, we have to multiple before we can subtract or add so start by multiplying 5*2*5 (easy to multiply 2*5 which equals 10 and then multiply it by the second 5 so 10*5=50; same thing for 4*2=8). now we can subtract 8 from 50 which we can rewrite as -50+8 if it's easier to think of it that way instead of 8-50 and we get a negative number (another way to think about it is we know the bigger number is negative so we subtract the big number and the small number and then put the negative sign in front like this: -(50-8)= -42)
if 2 1/2 kg of biscuit cost $15 , find the cost of 2kg of biscuits
It is a easy question btw ;-;
Step-by-step explanation:
[tex]2 \times \dfrac{1}{2} \: kg \\ \\ = \frac{5}{2} kg \\ \\ = 2.5kg[/tex]kg of biscuit cost $ 15 .
We have been asked to find the cost of 2Kg of biscuits.
First Let's find the cost of 1Kg biscuit
[tex] \tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = \dfrac{15}{2.5} \\ \\ \: \: \tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = 6 \: dollar[/tex]
Then Cost of 2Kg biscuit would be
[tex] \tt\implies \: cost \: of \: 1kg \: biscuit \: = 2 \times 6 \\ \\ \tt\implies \: cost \: of \: 1kg \: biscuit \: = \: 12 \: dollar[/tex]
Hence, the cost of 2 kg biscuit is 12$ .

The number 100 is reduced by 30%. The number X is the result of that calculation increased by 30%. The number Y is equal to 100.
Which statement is true?
Answer: Your equation will look like this, where “N” is the number and “R” is the intermediate result
N−(N∗30/100)=R
R+(R∗50/100)=525
Simplifying and solving for R, we get:
R+0.5R=525 ← reducing 50/100
1.5R=525 ← combining R terms
R=350 ← dividing both sides by 1.5
Now, we need to solve for N:
N−0.3N=350 ← reducing 30/100
0.7N=350 ← combining N terms
N=500 ← dividing both sides by 0.7
