Answer:

negative

Step-by-step explanation:

The graph has a negative slope because the line is pointing downwards.

You can check your answer numerically using the slope formula (y2 - y1 divided by x2 - x1) and substituting with two coordinates on the line.

For example:

(x1, y1)

(x2, y1)

y2 - y1

----------

x2 - x1

Solve by subtracting the numerator and denominator, then divide.

Using the normal distribution, the area underneath the shaded region <u>between the two z-scores</u> is given by:

C. 0.6766.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

Hence, for this problem, the area is the <u>p-value of z = 0.75 subtracted by the p-value of z = -1.3</u>.

Looking at the z-table, the p-values are given as follows:

z = 0.75: 0.7734.

z = -1.3: 0.0968.

Then:

0.7734 - 0.0968 = 0.6766.

Which means that option C is correct.

Aleena has a savings account that gives 5% annual interest. She deposits $200 that she received on her birthday. Write an equati

ANTONII [103]

Answer:the equation is 200 + 10x

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount deposited into the account.

R represents interest rate on the principal

T represents time in years

I = interest after t years

From the information given

T = x years

P = $200

R = 5%

Therefore

I = (200 × 5 × x)/100

I = 1000x/100

I = 10x

Therefore, the equation representing the total amount of money that would be in the account after x years would be

200 + 10x

Polygon q is a scaled copy of polygon p using a scale factor of 1/2 polygon q’s area is what fraction of polygon p’s area?

san4es73 [151]

Answer:

Polygon q’s area is one fourth of polygon p’s area

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> polygon q’s area

y-----> polygon p’s area

$z^{2} =\frac{x}{y}$

In this problem we have

$z=\frac{1}{2}$

substitute

$(\frac{1}{2})^{2} =\frac{x}{y}$

$(\frac{1}{4}) =\frac{x}{y}$

$x=\frac{1}{4}y$

therefore

Polygon q’s area is one fourth of polygon p’s area

You pick a card, roll a die, and find the sum. How many different sums are possible?

lawyer [7]

Answer:

Step-by-step explanation:

We know that the lowest number on a die is 1 and the lowest number on a card is 2. We can add these two together to find our first sum, 3.

Next, we will add our highest numbers; 6 + 10, which equals 16. Instead of solving for everything in between, since we have found the lowest and the highest and we are only looking for different sums, we can do the following:

16 - 2

You may be wondering why we would do 16 minus two instead of three. This is because three is included as one of the different combinations. The result of this formula is 14, so we know that there are 14 different combinations.
