Answer: She had 27.2% correct.

Step-by-step explanation: To find the percent, we can divide the part and whole then multiply the quotient by 100. After that we'll need to convert the percent to a decimal. In mathematical terms, the formula will be,

[tex]\frac{part}{whole}=quotient*100[/tex]

40% will be the part and 68% will be the whole.

Step 1.

Convert 40 into a decimal by dividing it by 100.

40 ÷ 100 = 0.4

Step 2.

Multiply 0.4 by 68.

0.4 × 68 = 27.2

Hence, she had 27.2% correct.

53 and 17

Step-by-step explanation:

If you add 53 and 17, you get 70.

If you subtract 17 from 53, you get 36. Hope this helps!

Answer: Graphed points I used, (-2,0), (0,-2), and (-3,-1)

Step-by-step explanation:

The graph of given function is attached below.

The given function is,

                          [tex]f(x)=-|x+2|[/tex]

We have to draw the graph of above function.

When [tex]x=-2[/tex] ,  [tex]f(-2)=0[/tex]

When [tex]x=-4[/tex] , [tex]f(-4)=-|-4+2|=-2[/tex]

When [tex]x=0[/tex], [tex]f(0)=-2[/tex]

Thus, We have points [tex](-2,0),(-4,-2)[/tex] and [tex](0,-2)[/tex]

Step-by-step explanation:

set up an equation:

let h be the number of hours you spent raking.

then, the cost would be 10 + 8 times the number of hours.

In equation form:

[tex]10 + 8h = 42[/tex]

solve:

[tex]10 + 8h = 42\\8h = 32\\h = 4[/tex]

So you worked for 4 hours

The moment generating function of each random variable is;

M(t) = (1/(1 - 1.5t))^(2), t < 2/3

Answer:

SD[X + Y] = 3

Step-by-step explanation:

For ease of differentiation, let's rewrite the M(t) function as;

M(t) = (1 - (3/2)t)^(-2)

Let's find the first derivative of the function;

M'(t) = 3(1 - (3/2)t)^(-3)

To get E[X], we will put 0 for t to get;

E[X] = 3(1 - (3/2)0)^(-3)

E[X] = 3

Now,let's find the second derivative of M(t)

M"(t) = (27/2)(1 - (3/2)t)^(-4)

At,t = 0, we will get E[X²]

Thus;

E[X²] = 27/2

Now, Var[X] = E[X²] - (E[X])²

Var[X] = (27/2) - 3²

Var[X] = 9/2

We are told that the times X and Y are independently and identically distributed. Thus, the sum of their variances is equal to the variance of their sum. This is expressed as;

Var[X + Y] = 9/2 + 9/2

Var[X + Y] = 9

Now,we know that square root of variance is standard deviation. Thus;

SD[X + Y] = √9

SD[X + Y] = 3

Pigeonhole Principle

Step-by-step explanation:

From series {1,2......2n} ; we need to select 'n + 1' integers.

Even integers series from above series = {2,4,6..........2(n-1), 2n}

Odd integers series from above series = {1,3,5........2(n-2), 2n-1}

So, we can choose only n odd integers from the series. Hence, if we choose n+1 integers, atleast one of them have to be even integer.

The percentage of oil that has leaked​ from the tank is 14.29%.

Given the following data:

To determine the percentage of oil that has leaked​ from the tank:

Mathematically, the percentage for the amount of oil leakage in this tank is given by this formula:

[tex]Percentage = \frac{Oil\;leakage}{Tank\;capacity} \times 100\\\\[/tex]

Substituting the given parameters into the formula, we have;

[tex]Percentage = \frac{7}{49} \times 100\\\\Percentage = 0.1429 \times 100[/tex]

Percentage = 14.29%.

Answer:

A. 57m   B. 130m

Step-by-step explanation:

For problem A:

87m up a cliff - 30m up a cliff = 57m up a cliff

These are all positive values

For problem B:

100m above is talking about a positive value, making this a positive number

30m below is talking about a negative value, making this number -30

0 meters represents the surface

As you can see, this is forming a number line as of which

below the surface------------------------0m-------------------------above the surface

by substitution,

-30-----------------------------------------------0-------------------------------100

therefore, 100 - -30 = 130 meters

=> we know that sum of both angle is equal

180°

=> because both angle are co-interior angle

=> let the unknown angle be x

=> so, X + 135° = 180°

=> x= 180 - 135

=> 45°
