Answer:

42

Step-by-step explanation:

Given that:

Sample space = {1, 2, 3, 4, 5,6}

Probability of obtaining an odd number in a single roll :

Probability = required outcome / Total possible outcomes

Required outcome = {1,3,5} = 3

Total possible outcomes = 6

P(odd number) = 3/6 = 1/2

Number of odds on 84 die rolls :

1/2 * 84 = 42 times

Answer:

y < 28

Step-by-step explanation:

get the y on its own

y/2 - 6 < 8

y/2 - 6 + 6 = y/2

8 + 6 = 14

y/2 < 14

y/2 x 2 = y

14 x 2 = 28

y < 28

What is the division?

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.

Here given that,

A lion weighs [tex]7[/tex] times as much as a leopard. The combined weight of the cats is [tex]480[/tex] pounds.

So, the weight of each cat is [tex]\frac{480}{7}=68.57[/tex].

Hence, the weight of each cat is [tex]68.57[/tex].

Answer:

11 ft

Step-by-step explanation:

The formula for the area of a rectangle of length L and width W is

A = L * W.  

Represent the length, L, by 2W + 1 ("1 more than twice the width").  Then the area formula (above) becomes:

A = 55 ft^2 = (2W + 1)(W), which, when simplified, results in:

2W^2 + W - 55 = 0, whose coefficients are {2, 1, -55}.  Let's use the quadratic formula to solve this for W:

The discriminant, b^2 - 4ac, is 1^2 - 4(2)(-55), or 441.  The square root of 441 is 21.  Thus, the quadratic formula gives us:

        -1 ± 21

W = ------------- = (1/4)(-1 + 21), or W = 5 and W = -22/4 = -11/2

            2(2)

A measure of length can't be negative, so we reject W = -11/2 in favor of W = 5.

Then, according to the formula for L that we found earlier, L  = 2W + 1, or

L = 2(5) + 1, or L = 11.

Check:  Does L * W result in an area of 55 ft²?  Yes

The length dimension of the rectangle is 11 ft

total degree inside pentagon is (n - 2) x 180 = 540

180-62 = 118

180-66 = 114

180-77 = 103

180-59 = 121

118+114+103+121 = 456

540 - 456 = 84

84 + 12x = 180

12x = 180-84

x = 96/12

x = 8

The value of x in the given pentagon is 8.

Option D is the correct answer.

A pentagon is a polygon that has five sides and five angles.

The sides and angles of a pentagon are not all equal unless it is a regular pentagon.

A regular pentagon has five equal sides and five equal angles.

We have,

For a pentagon, n = 5, so we have:

total degree = (5 - 2) × 180 degrees

total degree = 3 × 180 degrees

total degree = 540 degrees

Now,

Each angle makes a straight angle.

So,

77 + a = 180

a = 180 - 77 = 103

59 + b = 180

b = 180 - 59 = 121

c + 66 = 180

c = 180 - 66 = 114

d + 62 = 180

d = 180 - 62 = 118

Now,

a + b + c + d + e = 540

103 + 121 + 114 + 118 + e = 540

e = 540 - 456

e = 84

Now,

12x + 84 = 180

So,

12x = 180 - 84

12x = 96

x = 8

Thus,

The value of x is 8.

Answer:

g(n) = 18 - 4n

Step-by-step explanation:

Given the recursive formula

g(n) = g(n - 1) - 4 with common difference d = - 4 and g(1) = 14

The explicit formula for an arithmetic sequence is

g(n) = g(1) + (n - 1)d , then

g(n) = 14 - 4(n - 1)

       = 14 - 4n + 4

       = 18 - 4n

Answer:

Step 4.

Step-by-step explanation:

Given that Kayla uses mental math to find the product of $ 11.97x5, but she made a mistake, and knowing that her steps were the following:

Step 1: Round $ 11.97 to $ 12.

Step 2: multiply $ 12.00x $ 5 = 60

Step 3: subtract $ 12.00- $ 11.97

Step 4: subtract $ 60.00- $ 3.00 = 57.00.

To determine in which one is where Kayla made her first mistake, the following reasoning must be performed:

Rounding from 11.97 to 12 implies a difference of 0.03 that must be multiplied by 5, the result of which is 0.15.

Thus, from the result of 12 x 5 (60), 0.15 must be subtracted, and not 3, as was subtracted in Step 4. Therefore, Step 4 is the one where the error occurred.
