Answer: 325.623 rounded to the nearest tenth=325.6

Step-by-step explanation:

You take 325.623 and round the 23 on the end down because both numbers are less than five.

A bag contains 7 red marbles, 9 blue marbles, and 6 green marbles. what is the probability of choosing a marble that is not gree

skad [1K]

Probabilities! In order to find the answer you first have find out the total amount of marbles that you have. So:

[7 + 9 + 6] = 22

This number will go into the denominator.

The next step is to find how how many marbles are not green. To do that you simply add the red marbles and the blue marbles. So:

[7 + 9] = 16

This number will go in the numerator.

The probability of you choosing a marble that is not green is 16/22. You can also simply this and it would be 8/11.

Write the equation of a sine function that has the following characteristics.

slava [35]

Answer:

$\displaystyle y = 7\sin(9\pi(x + {1}/{4}) )$

Step-by-step explanation:

we are given

Amplitude:7
Period:9π
Phrase shift:¼

remember that,

$\displaystyle y = A \sin(B(x + C) )+ D$

where A is the Amplitude

B is the Period

C is the Phase shift

D is the vertical shift

note that, since D isn't given we'll take it 0

altogether substitute:

$\displaystyle y = 7\sin(9\pi(x + {}^{1}/_{4}) )+ 0$

hence,

our equation is

$\displaystyle y = 7\sin(9\pi(x + {}^{1}/_{4}) )$

and we are done!

8(4n + 3) = – 72<br> show your work

AfilCa [17]

Answer: n= −3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8(4n+3)=−72

(8)(4n)+(8)(3)=−72(Distribute)

32n+24=−72

Step 2: Subtract 24 from both sides.

32n+24−24=−72−24

32n=−96

Step 3: Divide both sides by 32.

32n/32 = −96/32

n=−3

Given segments AB and CD intersect at E.

nata0808 [166]

The length of a segment is the distance between its endpoints.

$\mathbf{AB = 3\sqrt{2}}$
AB and CD are not congruent
AB does not bisect CD
CD does not bisect AB

<u>(a) Length of AB</u>

We have:

$\mathbf{A = (1,2)}$

$\mathbf{B = (4,5)}$

The length of AB is calculated using the following distance formula

$\mathbf{AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}$

So, we have:

$\mathbf{AB = \sqrt{(1 - 4)^2 + (2 - 5)^2}}$

$\mathbf{AB = \sqrt{18}}$

Simplify

$\mathbf{AB = 3\sqrt{2}}$

<u>(b) Are AB and CD congruent</u>

First, we calculate the length of CD using:

$\mathbf{CD = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}$

Where:

$\mathbf{C = (2, 4)}$

$\mathbf{D = (2, 1)}$

So, we have:

$\mathbf{CD = \sqrt{(2 -2)^2 + (4 - 1)^2}}$

$\mathbf{CD = \sqrt{9}}$

$\mathbf{CD = 3}$

By comparison

$\mathbf{CD \ne AB}$

Hence, AB and CD are not congruent

<u>(c) AB bisects CD or not?</u>

If AB bisects CD, then:

$\mathbf{AB = \frac 12 \times CD}$

The above equation is not true, because:

$\mathbf{3\sqrt 2 \ne \frac 12 \times 3}$

Hence, AB does not bisect CD

<u>(d) CD bisects AB or not?</u>

If CD bisects AB, then:

$\mathbf{CD = \frac 12 \times AB}$

The above equation is not true, because:

$\mathbf{3 \ne \frac 12 \times 3\sqrt 2}$

Hence, CD does not bisect AB
