Answer:

{10, -8} (A)

Step-by-step explanation:

Since it is absolute value, n-1 can equal both 9 or -9.

First you solve for n-1=9.  That would make n=10

Then you solve for n-1= -9 .That would make n=-8

Answer:

A) {10, -8}

Step-by-step explanation:

Since it is absolute value, you must split it into two equations:

n-1=9

n-1=-9

Now solve for n in both equations

n=10

n=-8

Therefore, the answer is A

Answer:

D.) The expected value is 1.78

Step-by-step explanation:

The expected value of a probability distribution is evaluated using the formula.

Expected Value, [tex]E(X)=\sum^{n}_{i=1}x_iP(x_i)[/tex]

Therefore, from the given probability distribution, we have:

E(X)=(0*0.3)+(1*0.2)+(2*0.16)+(3*0.2)+(4*0.04)+(5*0.1)

E(X)=1.78

The Expected value of X is 1.78.

The correct option is D.

Answer:

The equation is true when x = 4 because 6(4) = 24 that is x=4 satisfies the given equation.

Step-by-step explanation:

Given: [tex]6x=24[/tex]

To find: x

Solution:

A equation is a statement that defines the equality of two expressions or numbers.

[tex]6x=24[/tex]

Divides both sides by 6

[tex]\frac{6x}{6}=\frac{24}{6}\\x=4[/tex]

Therefore,

The equation is true when x = 4 because 6(4) = 24 that is x=4 satisfies the given equation.

Answer:

Step-by-step explanation:

3p + q = 8 and

3p - q = 10

then p+q is?​

--------

add up side-by-side:

6p=18 ⇒ p=3

q=8-3p= 8 - 9= -1

p+q= 3-1=2

Answer:

2

Step-by-step explanation:

3p + q = 8

3p - q = 10

→ Minus the two equations away from each other which would cancel out 3p

2q = -2

→ Divide both sides by 2 to isolate q

q = -1

→ Substitute q = -1 back into 3p + q = 8

3p - 1 = 8

→ Add 1 to both sides to isolate p

3p = 9

→ Divide both sides by 3 to isolate p

p = 3

⇒ The question asks us to find p + q so,

3 + - 1

→ Remember the minus cancels out the plus

3 - 1 = 2

Answer:

66 cubic units

Step-by-step explanation:

For a prism, the volume is the area of the base multiplied by the height.

area of base = area of triangle = (1/2) * base * height (of the base)

volume = area of base * height of prism

volume = (1/2) * 4 * 3 * 11

volume = 66

Answer:

5

Step-by-step explanation:

4a + 6b = 24

6a - 12b = -6

Rewrite the first equation below. Divide both sides of the second equation by 2 and write below the first equation. Then add the equations.

      4a + 6b = 24

+     3a - 6b = -3

----------------------------

      7a         = 21

Divide both sides by 7.

a = 3

Now substitute 3 for a in the first equation and solve for b.

4a + 6b = 24

4(3) + 6b = 24

12 + 6b = 24

6b = 12

b = 2

a = 3, and b = 2

a + b = 3 + 2 = 5

Answer: 5

Answer:

S(t) = 10 - 0.5t

Step-by-step explanation:

initial depth of snow = 10 inches

melting rate =  0.5 inches per hour

it means that, in one hour snow depth will decrease by 0.5 inches

thus , in t hours  snow depth will decrease by 0.5*t = 0.5t inches

Thus, depth of snow after t hours can be calculated by

we will take initial depth of snow and them subtract the depth of snow which melted in t hours.

we are subtracting as snow is melting and will thus decrease the depth of snow

depth of snow after t hours can = initial depth of snow - decrease of the depth of snow after snow melts for t hours

depth of snow after t hours can = 10 inches - 0.5t inches

                                                       =  (10 - 0.5t )inches

Thus ,S(t), representing the depth of snow on Mason's lawn, in inches, t hours after the snow stopped falling is S(t) = 10 - 0.5t

Answer:

5/6

Step-by-step explanation:

On a standard 6-sided die, there is only one 2. That means that there are 5 other numbers that it could land on (1, 3, 4, 5, 6).

Using that information, the probability of it not landing on a 2 is 5 out of 6 or 5/6. This is because you must do part over whole. The "part" in this situation is the 5 "wanted" numbers, and the "whole" is 6 because there are six potential numbers that it could land on.

I hope this helps.

The probability that it will not land on a 2 is 5/6

Probability is the likelihood or chance that an event will occur.

It will land on 2, Prob (land on 2) = 1/6

It will not land on 2, the probability will be given as:

Prob (not land on a 2) = 1 - 1/6

Prob (not land on a 2) = 5/6

Hence the probability that it will not land on a 2 is 5/6

Answer:

i<3u

Step-by-step explanation:

Let's solve for i.

9x−7i>3(3x−7u)

Step 1: Add -9x to both sides.

−7i+9x+−9x>−21u+9x+−9x

−7i>−21u

Step 2: Divide both sides by -7.

−7i

−7

>

−21u

−7

i<3u

Hope this helps.

Answer: i < 3u

We first distribute 3.

9x-7i > 3 (3x-7u)

9x-7i > 9x - 21u

Subtract 9x from both sides.

-7i > -21u.

Divide both sides by -7. Since -7 is negative so the inequality sign will change.

i < 3u.

Answer:

36

Step-by-step explanation:

Let Brandon's age be b. We can write 4b = b + 27 which gives us b = 9. Because Michael is 4 times as old as Brandon, he is 9 * 4 = 36 years old.

Answer:

36

Step-by-step explanation:

Micheal is 4 times as old as Brandon.

y = 4x

Micheal is also 27 years older than Brandon.

y = x +27

Y represents Micheal's age, and x represents Brandon's age.

Since both equations above are equal to the same value, y, you can set the two equations equal to each other.  Solve for x.

4x = x + 27

3x = 27

x = 9

Brandon is 9 years old.  

Plug Brandon's age into one of the equation to solve for Micheal's age.

y = x + 27

y = 9 + 27

y = 36

Micheal is 36 years old.

Answer:

3 < 5

Step-by-step explanation:

3 < 5

We can write this inequality, because three is less than five, and < means less than.

An inequality is a mathematical sentence which

states that two expressions are not equal.

The "<" symbol means less than.

Since 3 is less than 5, we can write this as 3 < 5.

Answer:

C

Step-by-step explanation:

this is because perpendicular lines have the opposite reciprocal slopes. So, 3/2 is the opposite reciprocal of -2/3 since it is negative and that is the opposite sign. Then, it is the reciprocal of the fraction since the numerator and the denominator are switched. If you check the other answer options, you will see that none of the slopes are the exact opposite reciprocal.
