Answer:

there are 12 dogs.

Step-by-step explanation:

d= dogs              now plug in the 4 into your equation.

c= cats                  d=3(4)

d+c=16                   d=12

3c+c=16

4c=16                        SO THEREFORE THERE ARE 12 DOGS :)

c=4

Answer:

3.3 PB

Step-by-step explanation:

It is given tat the population of the U.S = 326,891,705 people.

Population expected to use the app in first 4 months = 1/10 of 1%

Storage capacity of an user is = 10 GB

Therefore,

[tex]$\frac{1}{10} \text{ of}\ 1$[/tex] % = 0.1%

               = 0.001

The user content = 0.001 x 326,891,705

                            = 326891.705 users

10 GB storage per user.

Therefore,

Size =   326891.705 x 10

       =  3268917.05 GB

       = 3.26 PB

Hence size of the minimum storage would be 3.3 PB.

Answer:

  18 feet

Step-by-step explanation:

The ladder length represents the hypotenuse of a right triangle with a base of 9 and an unknown height (h). We can find that height by using the Pythagorean theorem.

  9² +h² = 15²

  h² = 225 -81 = 144

  h = √144 = 12

So, the ladder extends 12 feet up the side of the building. That is the height of the roof. The top of the flagpole is 6 feet above that, so the top of the flagpole is ...

  12 ft + 6 ft = 18 ft

above the ground.

The height to the top of the flagpole is 18 feet.

Answer:

This explanation is not correct

Explanation:

Significance level is the probability that the null hypothesis rejected is in fact true. If we say there is a significance level of 0.10 or 10%(α=0.10 level) then there is a 10% chance of incorrectly rejecting the null hypothesis when there is actually no difference.

If we wish to reach a conclusion on rejection or acceptance of the null hypothesis, we could use the p value(the probability that observed results or more extremee results are true given null hypothesis)which we compare with the significance level to conclude. If the significance level is 0.10 and p value is 0.07(since p value is less than significance level) , we reject the null hypothesis and vice versa.

The significant level, α = 0.05 level specifies a probability of the correctness of the null hypothesis.

Reasons:

The significant level specifies the the likelihood of rejecting a true null

hypothesis, such that a 5% significance level indicates that the risk of

drawing a conclusion that there is a difference in a sample, when the

samples are similar is 5%, and therefore, the probability that null

hypothesis is true is 5% or 0.05.

The level of significance is a specification that indicates the amount of

evidence required within a sample to allow the rejection of the null

hypothesis, and reach a conclusion that the observed effect is statistical

significant at the α = 0.05 level.

Therefore;

The statement by the student that "This means that the probability that the null hypothesis is true is less than 0.05" is correct.

Answer:

The algebraic expression will be:

Step-by-step explanation:

Given the statement in English words

''8 less than the product of 6 and a number is the same as 5 more than the number''.

Let us break down the statement into an algebraic expression

FIRST PART

Let 'n' be the number

so

The product of '6' and a number 'n' = 6n

∵Because 6 is a coefficient and n is a variable

now

8 less than the product of 6 and a number 'n' will be: 8-6n

2ND PART

5 more than the number 'n' means we need to add '5' into a number 'n'

i.e

5+n

COMBINE STATEMENT

Thus, the combined statement ''8 less than the product of 6 and a number is the same as 5 more than the number'' can be written as:

8-6n = 5+n

Thus, the algebraic expression will be:

VERIFICATION:

Let us verify by finding the value of n

8-6n = 5+n

8-5 = 7n

7n = 3

n = 3/7

substituting n=3/7 in the equation

8-6n = 5+n

8 - 6(3/7) = 5+(3/7)

38/7 = 38/7

TRUE

Thus, the equation is true.

Answer:

  1/18

Step-by-step explanation:

18 is a suitable denominator for both fractions:

  5/6 = 15/18

  7/9 = 14/18

Then the difference is ...

  5/6 -7/9 = 15/18 -14/18 = (15 -14)/18 = 1/18

I think it's ''4 4/5"..

Answer:

25%

Step-by-step explanation:

Initial no of students = 16,000

Final no of students = 20,000

We need to find the percent increase in enrollment.

The increase in no of students = 20,000 - 16,000

= 4000

Percentage = (increase/initial no of students) × 100

[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]

Hence, the percent increase is 25%.

Step-by-step explanation:

I don't really know how to explain it, so I'll show you instead.

For science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

So,

0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.016

For English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

So,

0.25 x 0.25 x 0.25 x 0.25 = 0.004

They will have to study English (0.004) because it is lower than science (0.016).

The quiz he should study is; English because the probability of getting all questions correct is 0.004 which is lower than for science (0.016).

We are told that for science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

Thus;

P(6) = 0.5⁶ = 0.016

We are told that for English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

Thus; P(4) = 0.25⁴ = 0.004

Thus, we conclude that they will have to study English because the probability of getting all questions correct is 0.004 which is lower than for science (0.016).
