The answer would be 5*C or 5C or 5(C) they all mean the same exact thing but if Kevin has 5 times as much no matter what billy has you’ll have to multiply that by 5 to see how much Kevin’s has so if billy has c then you multiply that by 5

Answer:

Step-by-step explanation:

__________________________________________________________

B is the answer because,

if the negative sign is not inside the "brackets," then the number will still be negative.

But, if the negative sign is connected to the number, or inside the "brackets," then it will always be positive.

__________________________________________________________

Here are the reasons why the rest are wrong.

A is not correct because the outcome isn't negative, even though it's correct in mathematical instances.

C is not correct because it is plainly not correct in itself.

D is also not correct because it is not correct in the mathematical equations, even though it has a -9 as the equal, it's still wrong.

At a large university, 434 freshmen, 883 sophomores, and 43 juniors are enrolled in an introductory algorithms course. How many sections of this course need to be scheduled to accommodate all these students if each section contains 34 students?

Answers

Answer: it will take 40 sections the course to accommodate all the students

Step-by-step explanation:

Given that;

434 freshmen, 883 sophomores and 43 juniors are enrolled

total number of students enrolled = (434 + 883 + 43) = 1360

number of student in one section = 34

now

number of sections of an introductory algorithms course needed to be scheduled to accommodate all these students will be;

Total number of section = total number of students enrolled / number of student in one section

so we substitute

Total number of section = 1360 / 34

Total number of section = 40

Therefore it will take 40 sections the course to accommodate all the students

your 3 math answer scores are 75,98 and 91 what is your average score​

Answers

Answer:

88

Step-by-step explanation:

It is given that,

Three scores are 75,98 and 91.

We need to find average score.

The formula to find the average is given by :

[tex]\text{Average}=\dfrac{\text{sum of observations}}{\text{total no of observations}}[/tex]

Using the above formula,

[tex]A=\dfrac{75+98+91}{3}\\\\=88[/tex]

Hence, my average score is 88.

if 4/3 x 3/4 = 5k, then k = ?​

Answers

Answer:

k= 1 /15 x^3

Step-by-step explanation:

4/3 x 3/4 = 5k

5k= 1 /3 x^3

k= 1 /15 x^3

The required value of k in the given equation (4/3) × (3/4) = 5k is 1/5.

To find the value of k in the equation (4/3) × (3/4) = 5k, we need to simplify the left side of the equation and solve for k.

Multiplying the fractions on the left side:

(4/3) × (3/4) = 12/12 = 1

Now we have the equation 1 = 5k. To solve for k, we need to isolate it on one side of the equation.

Dividing both sides of the equation by 5:

1/5 = k

Hence, the value of k in the given equation is 1/5.

Answers

Complete question :

Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.

1. State the appropriate null and alternate hypotheses.

2. Compute the P-value.

Answer:

H0 : p = 0.5

H1 : p < 0.5

P value = 0.200454

Step-by-step explanation:

Given that :

Claim : Less than half internet users have posted photos or videos online.

Sample Proportion (p) = 865 / 1765 = 0.4900

The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.

The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;

P = 0.5

q = 1 - 0.5 = 0.5

The test statistic :

Z = p - p0 / sqrt(p0 * (q/n))

Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))

Z = - 0.01 / sqrt(0.5 *0.0002832)

Z = - 0.01 / sqrt(0.0001416)

Z = - 0.01 / 0.0119013

Z = - 0.8402443

The corresponding p value from the z statistic score at α = 0.01

= 0.200454

Answers

Answer:

3.188

Step-by-step explanation:

Given that :

Sample data: 26.5, 28, 30.2, 29.6, 32.3, 24.7

Sample standard deviation (s) = 2.728

Mean (mu) = 25

Tstatistic formula :

(x - mu) / (s/sqrt(n))

n = sample size = 6 ; s = 2.728 ; mu = 25

Sample mean (x) = (26.5 + 28 + 30.2 + 29.6 + 32.3 + 24.7) / 6

Sample mean (x) = 171.3 / 6 = 28.55

Tstatistic = (28.55 - 25) / (2.728 / sqrt(6))

Tstatistic = 3.55 / 1.1137013

Tstatistic = 3.1875692
