The percentage of the automobiles that have an average miles per gallon between 38.7 miles per gallon and 48.9 miles per gallon is 68%

1 std above mean = M + d = 43.8  + 5.1 = 48.9

1 std below the mean, = M - d = 43.8 - 5.1 = 38.7

The probability between one standard deviation below the mean and one standard above the mean = 34% + 34% = 68%

Thus, the percentage of the automobiles that have an average miles per gallon between 38.7 miles per gallon and 48.9 miles per gallon is 68%.

To find the average number of pages the student read from day 2 to day 6, add the total pages in these days and divide by 5 days.

This is a very common word used in mathematics and stadistics to refer to the mean value in a set of values.

Add the pages the person read these days and then divide by 5 (total of days).

For example:

35 + 45 + 10 +25 + 20 = 135 / 5 = 27 pages

%70

Step-by-step explanation:

percentage can be found by dividing the values than multiplying the values by 100

Formula: (value/totalvalue)100

plug in the formula with what we have;

28/40(100)

→ First step; dividing our value by total value (28/40)

28/40 = 0.7

  → Second step; multiplying our value by 100 (0.7)

0.7 * 100 = 70

Therefore cora got %70 correct on her grammar sheet

Answer:

Answer:

X = 10

Step-by-step explanation:

Since 2x = 20

we can divide 2 from both sides giving us x = 20/2

Therefore , x = 10 because 20 divided by 2 is 10

Answer:

X= 10

Step-by-step explanation:

2X=20

Then Divide both sides by 2 in order to find the value of X

2X/2=20/2

Answer:

67.5 kg

Step-by-step explanation:

To determine the weight of 45 books, we need to determine the weight of one book, using the equation (30 books = 45 kg). This can be done by dividing 30 to both sides of the equation. Therefore,

We obtained the following equation;

Now, multiply both sides by 45 to determine the weight of 45 books.

Therefore, the weight of 45 books is 67.5 kg.

Answer:

[tex]\huge\boxed{\bf{45books = 67.5kg}} [/tex]

Step-by-step explanation:

Given:-

To find:-

Ans:-

30books = 45kg

45books = y kg

Let's find 45 books (y)

[tex]\sf \to \frac{30}{45} = \frac{45}{y}[/tex]

[tex]\sf \to 45*45 = 30*y[/tex]

[tex]\sf \to 2,025 = 30*y[/tex]

[tex]\sf \to y = \frac{2,025}{30}[/tex]

[tex]\sf \to y = 67.5kg[/tex]

The true statement regarding the facts provided in the table is given by: Option D:  the payment amount each month stays the same.

Amount whose value increases from its past value is called increasing amount.

The missing table is attached below.

Checking the validity of each option:

We see from the table that interest in each previous month is bigger than next month, for example, in first month, it was $56.33, and in next month, it was $54.99, so interest is decreasing.

Thus, this option is not correct.

The principal amount in any previous month is smaller than the next month principal amount. For example, in first month, the principal amount was $184.96 and in next month, it became $186.33, so the principal amount is increasing.

Thus,  this option is not correct.

Option C is false and option D is true. It is because the payment is constant $241.32(iie, it doesn't change, and therefore stays the same) in each of the months.

Thus, the true statement regarding the facts provided in the table is given by: Option D:  the payment amount each month stays the same.

The Probability of red light is 0.3

P(red) = 0.3

The probability that out of the next eight eastbound cars that arrive randomly at the light, exactly three will be stopped by a red light be 0.25.

P(exactly three get stopped by red light)=0.25

The correct option is (d) P(red)=.3,P(exactly 3 get stopped)=.25

A binomial distribution can be thought of as simply the probability of a SUCCESS or FAILURE outcome in an experiment or survey that is repeated multiple times.

The occurrence,

p= probability of a red light

 =[tex]\frac{15}{15+5+30}[/tex]

 = [tex]\frac{15}{50}[/tex]

 = 0.3

Hence, Probability of getting red light be,

P (red)= 0.3

Now, the Binomial distribution formula,

Probability=( [tex]_r^nC[/tex])[tex]\;p^{r} \;q^{n-r}[/tex]

where, r = number of times for a specific outcome within n trials

[tex]_r^nC[/tex]   = number of combinations

p = probability of success on a single trial

q = probability of failure on a single trial

n = number of trial

According to question,

          = 1- 0.3

          = 0.7

Now using the formula, ( [tex]_r^nC[/tex])[tex]\;p^{r} \;q^{n-r}[/tex]

P( exactly 3  get stopped) = ( [tex]_3^8C[/tex])[tex]\;(0.3)^{3} \;(0.7)^{8-3}[/tex]

                                            = [tex]\frac{8!}{3!(8-3)!}[/tex] [tex](0.027) \; (0.7)^{5}[/tex]

                                           =  [tex]\frac{8!}{3!(5)!}[/tex][tex](0.027) \; (0.16807)[/tex]

                                           = [tex]\frac{8 * 7 * 6 }{3 * 2}[/tex] x 0.027 x 0.16807

                                           = 56 x 0.00453789

                                           = 0.25412184

                                          ≈ 0.25

Hence, Probability of next eight eastbound so that exactly three will stopped by a red light be 0.25.
