Answer:

From the graph we can say that ant is moving faster than the ladybug

Slope of the ant's movement will be steeper than the ladybug

Unit rate/slope of the graph is (distance traveled/elapsed time)

Remember ant will take less time to travel a certain distance than ladybug.

Answer:

the value of the z is -3.5

Step-by-step explanation:

According to the question, the following information is given

-2z - 7

Based on the above information

We assume that we have to determine the z value

so

-2z - 7 = 0

-2z = 7

z = 7 ÷ -2

= -3.5

Hence, the value of the z is -3.5

The same is to be considered and relevant too

Given:

The different relations in the options.

To find:

The relation which represents a function.

Solution:

A relation is called a function if there exist a unique output (y-value) for each input (x-value).

In option A, there exist two outputs y=7 and y=1 for a single input x=-1. So, this is not a function.

In option B, there exist two outputs y=-5 and y=2 for a single input x=-1. So, this is not a function.

In option C, there exist two outputs y=2 and y=4 for a single input x=3. So, this is not a function.

In option D, there exist only one value of y for each x. So, this is a function.

Therefore, the correct option is D.

Answer:

276

Step-by-step explanation:

Given :

Standard deviation (σ) = 2.9 inches

Error margin (E) = 0.45

Confidence interval = 99%

Using the relation to obtain the sample size (n)

n = [(Zcrit * σ) / E]²

Zcritical at 99% confidence interval = 2.576

n = [(2.576 * 2.9) / 0.45]²

n = [7.4704 / 0.45]²

n = 16.600888^2

n = 275.58951

n = 276 samples

Explanation:

There are 3 possible cases that describe the relationship between the mean and median of the collected data.

First case:

If the distribution is symmetric then, mean = median.

Second case:

For the positively skewed frequency distribution, the mean is greater than the median.

Third case:

For the negatively skewed frequency distribution mean is less than the median.

Answer:

The value of the number is: n = -20

Step-by-step explanation:

Given

A number increased by five is negative fifteen.

To determine

What is the number?

Let 'n' be the unknown number.

''A number increased by five'' means we have to add 5 to the number.

i.e.

n+5

Also, it is stated that a number increased by five is negative fifteen.

Thus,

solving for n

[tex]n+5=-15[/tex]

Subtract 5 from both sides

[tex]n+5-5=-15-5[/tex]

Simplify

[tex]n=-20[/tex]

Therefore, the value of the number is: n = -20

Answer:

C. x+x+x+1+1+1 and 3(x+1)

Step-by-step explanation:

Algebraic Expressions

Some algebraic expressions are equivalent to others if the correct operations are done on them.

A. 10(x+4) must be operated by multiplying 10 by x and 10 by 4, thus:

10(x+4) = 10x + 40.

This choice is not correct

B. 3(x+5) must be operated by multiplying 3 by x and 3 by 5, thus:

3(x+5) = 3x + 15.

This choice is not correct

C. x+x+x+1+1+1 is equivalent to an expression where like terms are collected, that is. x+x+x=3x and 1+1+1=3, thus:

x+x+x+1+1+1=3x+3=3(x+1)

This choice is correct

D. x+x+x+x+1+1+1+1 in a similar way as explained above, like terms must be correctly collected: D. x+x+x+x=4x and 1+1+1+1=4, thus

D. x+x+x+x+1+1+1+1 = 4x+4 = 4(x+1)

This choice is not correct

Answer

Here's why this is correct

and if Elena gets a base pay of $1,500 per month, then we add 8% of the total sales, ($32,000) and 8% of 32,000 is $2,560.

8% of 32,000 = 2,560

So we add $2,560 by $1,500 and we get 4060 Dollars.

Answer:

186/25 i am pretty sure

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

It's c because you need the sum of x and 10 but both multiplied by 2. So it wouldn't be A nor B because they are both subtracting. That would leave you with C and D and d doesn't have anything to do with multiplying. I dunno made sense to me.

12 students play defense. 1st step.  6/9 of 27 is 18.  2nd. the ratio of the students playing offense to the total number of students playing soccer is 1 to 3 which means the total amount of students is '3', in the ratio it's 3 because it's simplified (i like to think of it as 'groups'). since we know that there are a total of 18 students and there's 3 total 'groups' we divide 18 into 3 which is 6. so there's 6 students in each group. we subtract 6 (1 group) from 18 ( the total number of students) which is 12, so there are 12 students playing defense. if you wrote the ratio again without simplifying it would be  6:18

Answer:

C - He substituted incorrectly when calculating the constant of variation.

The first error, in Nick’s work is given inn option C, i.e. He substituted incorrectly when calculating the constant of variation.

Constant of variation is the ratio between two variables in a direct variation or the product of two variables in an inverse variation.

We have,

s = 4, and t = 12

Now according to the question,

The variable s varies directly as the square of t,

i.e.

s = kt²

So,

Substituting given values of s and t,

s = kt²

i.e.

4 = k × 12²

⇒

[tex]k = \frac{4}{144}=\frac{1}{36}[/tex],

Now,

for 48,

i.e.

s = kt²,

We get,

[tex]48 = \frac{1}{36} t^2[/tex],

i.e.

[tex]t^2=36 *48=1728[/tex]

[tex]t=\sqrt{1728} = \sqrt{3*576} =24\sqrt{3}[/tex]

So, this is the correct value for t.

Hence, we can say that the first error, in Nick’s work is given inn option C, i.e. He substituted incorrectly when calculating the constant of variation.
