Step-by-step explanation:

Pythagorean theorem: b² + 6² = 14²

b² = 14² - 36² = 160

b = 4√10

sin(A) = 6/14 = 3/7

∠A = arcsin(3/7) ≈ 25.4°

∠B ≈ 90° - 25.4° = 64.6°

Eli buys milk and lemons at the store.
He pays a total of $50.59.
He pays a total of $6.35 for the milk.
He buys 7 bags of lemons that each cost the same amount.

How much does each bag of lemons cost?

Answers

Answer:

$6.32

Step-by-step explanation:

m + L = total $

6.35 + 7L = 50.59

Graph x > 1. WILL MARK BRAINLY

Answers

You have the correct answer. The graph of x > 1 involves an open hole at 1 and the shading is to the right. This visually describes any x value that is greater than 1. So for instance, x = 2 works but x = 0 does not.

The open hole means we exclude x = 1 itself from the shaded solution set.

A complex electronic system is built with a certain number of backup components in its subsystems. One subsystem has four identical components, each with a probability of 0.2 of failing in less than 1000 hours. The subsystem will operate if any two of the four components are operating. Assume that the components act independently.a) Find the probability that exactly two of the four components last longer than 1000 hours.b) Find the probability that the subsystem operates longer than 1000 hours.

Answers

Answer:

a) 0.1536 = 15.36% probability that exactly two of the four components last longer than 1000 hours.

b) 0.9728 = 97.28% probability that the subsystem operates longer than 1000 hours.

Step-by-step explanation:

For each component, there are only two possible outcomes. Either they fail in less than 1000 hours, or they do not. The probability of a component failing in less than 1000 hours is independent of any other component. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

One subsystem has four identical components, each with a probability of 0.2 of failing in less than 1000 hours.

Four components means that [tex]n = 4[/tex]

Probability of 0.2 of failling means that 1 - 0.2 = 0.8 probability of not failling, so [tex]p = 0.8[/tex]

a) Find the probability that exactly two of the four components last longer than 1000 hours.

This is [tex]P(X = 2)[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{4,2}.(0.8)^{2}.(0.2)^{2} = 0.1536[/tex]

0.1536 = 15.36% probability that exactly two of the four components last longer than 1000 hours.

b) Find the probability that the subsystem operates longer than 1000 hours.

It will operate if at least two compoents last longer than 1000 hours. So

[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{4,2}.(0.8)^{2}.(0.2)^{2} = 0.1536[/tex]

[tex]P(X = 3) = C_{4,3}.(0.8)^{3}.(0.2)^{1} = 0.4096[/tex]

[tex]P(X = 4) = C_{4,4}.(0.8)^{4}.(0.2)^{0} = 0.4096[/tex]

[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.1536 + 0.4096 + 0.4096 = 0.9728[/tex]

0.9728 = 97.28% probability that the subsystem operates longer than 1000 hours.

Angela plans to buy new flooring for her bedroom. Her bedroom floor is a rectangle that is 7.9 meters by 6.2 meters. a. How many square meters of floor space does her bedroom have? meters squared b. Suppose the flooring costs $5.90 per square meter. How much will the flooring cost? (use a dollar sign and NO SPACES)

Answers

part A is 48.98 meters squared. part B is $288.982.

Step-by-step explanation:

To find the area of the flooring you multiply 7.9 and 6.2 which gives you 48.98 meters squared. Then for part B you take your product from part A and multiply it by $5.90, giving you $288.982.

The answer is B.
Each person would get .75 cups. And there are two who don’t drink juice. .75 + .75 is 1.5

Answer:

B. 1.5 cups

Step-by-step explanation:

6/8 = 0.75

each person gets 0.75 each

Since 2 people chose not to drink the juice. the left overs would be 0.75*2

E. H0:μB−μA=0Ha:μB−μA>0H0:μB−μA=0Ha:μB−μA>0

Answers

Answer:

Option A.

Step-by-step explanation:

The representative will conduct a hypothesis test to test whether the mean number of magazines of type A the operators sell, μAμA, is greater than the mean number of magazines of type B the operators sell, μBμB. What are the correct null and alternative hypotheses for the test?

To verify this, the distribution used is [tex]\mu_{A} - \mu_{B}[/tex]

The null hypothesis is an equality, which means that it is:

[tex]H_{0} = \mu_{A} - \mu_{B} = 0[/tex]

At the alternate hypothesis, we want to test if the mean number of type A is greater than type B, that is, the distribution is positive. So

[tex]H_{A} = \mu_{A} - \mu_{B} > 0[/tex]

So the correct answer is given by option A.

The chart below shows one store’s sales of computers, listed by model. 2 circle graphs. A circle graph titled May. Poreg, 262; Quilren, 282; Dinztop, 223; Quilren 2, 135; Juvanto, 148. A circle graph titled June. Poreg, 173; Quilren, 184; Dinztop, 148; Quilren 2, 153; Juvanto, 212. If the changes in sales between May and June continue at the same percent rate, how many Dinztop computers will be sold in July? a. 73 b. 98 c. 142 d. 184

Answers

Answer:

b. 98

Step-by-step explanation:

May and June:

May: 223 Dinztop sales

June: 148 Dinztop sales.

So

[tex]p = \frac{148}{223} = 0.6637[/tex]

In June, it sold 0.6637 = 66.37% the amount of computers sold in May.

How many Dinztop computers will be sold in July?

Because of the same percent rate, 0.6637 = 66.37% of the amoutns sold in June.

0.6637*148 = 98

The correct answer is given by option b.
