Step-by-step explanation:

the line EB is parallel to the side of the triangle DC and intersects the other 2 sides proportionally , that is

[tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex] ( substitute values )

[tex]\frac{14}{12}[/tex] = [tex]\frac{AB}{18}[/tex] ( cross- multiply )

What's the answer to this question? 4*(5t+1)/5

Answers

Answer:

[tex]\boxed{\sf{4t+\dfrac{4}{5} }}[/tex]

Step-by-step explanation:

In order to solve this, you must use the distributive property.

[tex]\sf{\dfrac{4\left(5t+1\right)}{5}}[/tex]

Distributive property:

⇒ A(B+C)=AB+AC


⇒ 4(5t+1)

Multiply by expand.

4*5t=20t

4*1=4

Rewrite the problem down.

20t+4

20t+4/5

[tex]\text{FRACTION RULES: }\\\\\\\Longrightarrow: \sf{\dfrac{A\pm \:B}{C}=\dfrac{A}{C}\pm \dfrac{A}{C}}[/tex]

[tex]\Longrightarrow: \sf{\dfrac{20t+4}{5}=\dfrac{20t}{5}+\dfrac{4}{5}}[/tex]

You have to divide the numbers from left to right.

⇒ 20/5=4

[tex]\Longrightarrow: \boxed{\sf{4t+\dfrac{4}{5} }}[/tex]

Therefore, the correct answer is 4t+4/5.

Answer:

In a survey of 800 people, 42% said they shopped online last week. How many people said they shopped online last week?

Answers

explanation:

percent. part

_______ = _____

100. whole

42. ?

____ = ____

100. 800

cross multiply

800×42=33,600

then divide by 100

33,600/100=336

Answer:

336

Step-by-step explanation:

If 42% said they shopped online last week, that means the number of people who said they shopped online last week is 42% of 800. "Of" just means we should multiply, and since 42% = 42/100 (since % is just /100), we can use the following to find the answer (I used cross multiplication to simplify):

42          800         42         8

---    *               =     ----    *       =     336

100                           1

The group wants to travel from its current location on the map to the South Pole, and then directly back to the base camp. How many miles will they have to travel? Explain your answer.​

Answers

Using the Pythagorean Theorem, it is found that the group will have to travel 90 miles.

What is the Pythagorean Theorem?

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem:

First, the group travels 5 x 5 = 25 miles to the south pole.Then, the distance to the camp is the hypotenuse of a right triangle with sides of 25 miles and of 12 x 5 = 60 miles, hence:

[tex]d^2 = 25^2 + 60^2[/tex]

[tex]d = \sqrt{25^2 + 60^2}[/tex]

d = 65.

The total distance is given by:

Td = 25 + 65 = 90 miles.

Professor Mallory determines the distribution of students on five variables in her target population. She then uses nonprobability sampling to select students who fill the pre-established proportions of people in each combination of variables. Which sampling strategy did she use

Answers

The sampling strategy she use was a quota.

Quotas are meant to establish boundaries on the number of specific goods that are allowed to be lawfully imported into the country throughout a distinct period of time. In that, quotas are similar embargoes, except quotas don´t have explicit political purposes as embargoes do.

A Fixed quota would be a maximum amount not to be surpassed, while a tariff rate surcharge allows it, but with a higher duty.

The answer to the limitation of the Chi Square test (and all tests of hypothesis) about relationships between variables  is none of the above.

What is the limitation of the chi square test?

The Limitation of this type of test is in its sample size requirements, as there is a lot of difficulty of interpretation when samples are large.

Note that Chi Square test and all tests of hypothesis can tell us if relationships between variables are significant, random and also if it occurred by chance and as such they are no limitations here.

Answers

Answer:

16

Step-by-step explanation:

The figure shown is a trapezoid

Area of a trapezoid = 1/2(bottom base length + top base length) × height

Bottom base length = 7 units

Top base length = 1 unit

Height = 4 units

So area = 1/2 ( 7 + 1 ) × 4

==> add 7 and 1

Area = 1/2 (8) × 4

==> multiply 1/2 and 8

Area = 4 × 4

==> multiply 4 and 4

a tuba creates a 4th harmonic of frequency 116.5 hz what is the length of the pipe in the tuba

Answers

Since the tuba creates a 4th harmonic of frequency 116.5 hz, the length of pipe in tuba is 6.57 m

Since the tuba is an closed-pipe instrument, we need to find the frequency of a closed pipe

What is the frequency of an closed pipe?

The frequency of a closed pipe f = nV/4L where

n = harmonic V = speed of sound and L = length of pipe in tubaLength of pipe in tuba

Making L subject of the formula, we have

L = nV/4f

Since the tuba creates the 4th harmonic with frequency 116.5 Hz.

n = 9 and f = 116.5 Hz

Substituting the values of the variables into the equation, we have

L = nV/4f

L = 9 × 340 m/s/4 × 116.5 Hz

L = 3060 m/s ÷ 466 Hz

L = 6.57 m

So, the length of pipe in tuba is 6.57 m

A newly formed life insurance company has underwritten term policies on 120 women between the ages of forty and forty-four. Suppose that each woman has a 1/150 probability of dying during the next calendar year, and that each death requires the company to pay out $50,000 in benefits. Approximate the probability that the company will have to pay at least $150,000 in benefits next year

Answers

The probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

The probability of dying:

P(dying) = 1/150

P(living) = 1 - P(dying) = 1 - 1/150 = 140/150

There are 120 women.

P(x≥3) = 1 - [P(x=0) +P(x=1) + P(x=2)]

[tex]\rm P(x\geq 3)=1-[(120 \ choose \ 0)(1/150)^0)((149/150)^{120})+[/tex]  

                  [tex]\rm (120 \ choose \ 1) ((1/150)^1) ((149/150)^{119}) +[/tex]

                  [tex]\rm (120 \ choose \ 2)((1/150)^2)((149/150)^{118})][/tex]

P(x≥3) = 0.047

Thus, the probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.
