Step-by-step explanation:

to do something like this, you could just multiply both sides by 2. So now, you have 18/10, and 20/10. The one in between that would be 19/10

Answer:

In 25% of the games at least 55 points were scored.

Step-by-step explanation:

Percentage:

Number of desired outcomes multiplied by 100 and divided by the number of total outcomes.

In this question:

8 total games

In 2 at least 55 were scores.

100*2/8 = 100/4 = 25%

In 25% of the games at least 55 points were scored.

Answer:

The milk to water ratio in the new mixture is 3:2.

Step-by-step explanation:

Given that in a mixture of one hundred liters of milk and water the ratio of milk and water was 4: 1, to determine what is the ratio of milk to water in the new mixture when 25% of the mixture is removed and the same amount of water is added, the following calculation must be performed:

(100/5) x 4 = 80

80 liters of milk

20 liters of water

80 x 0.75 = 60

20 x 0.75 = 15

15 + 25 = 40

60 + 40 = 100

Thus, the milk to water ratio in the new mixture is 3:2.

Answer:

Step-by-step explanation:

From L to M,

change in x-coordinates = 8-2 = 6

change in y-coordinates = 3-7 = -4

Extrapolate from M(8,3) to find the other end of the segment:

8 + 6 = 14

3 - 4 = -1

Endpoint of segment: (14,-1)

Answer:

= 1.156 × 10^9

(scientific notation)

= 1.156e9

(scientific e notation)

= 1.156 × 10^9

(engineering notation)

(billion; prefix giga- (G))

= 1156000000

Step-by-step explanation:

Simply subtract A from B = 1,156,000,000 and convert the answer to scientific notation.

Answer:

D. 1.156 times 10^9

First we subtract the difference,

1,300,000,000 - 144,000,000 = 1156000000

Next, we find the number 1156000000 written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 115,600,000

New Number: 1.15600000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 1 5 6 0 0 0 0 0

Decimal Count:   1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.156 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.156 x 108

Step 4

Check your work:

108 = 100,000,000 x 1.156 = 115,600,000

Thus, 115,600,000 written in scientific notation is 1.156 times 10^9 estimated.

What is your question

Step-by-step explanation:

Answer:

x < -10

Step-by-step explanation:

Given the inequality 5 - 3x > 35

Subtract 5 from both sides

5 - 3x - 5> 35 -5

-3x > 30

Divide both sides by -3

-3x/-3 < 30/-3

x < -10 (note the change is sign)

hence the correct solution is x < -10

Answer:

C=12.5

Step-by-step explanation:

you do 4x2 for 8 then you do 100/8 getting you 12.5

Answer:

1) m = 5

2) c = 12.5

Step-by-step explanation:

1) T = 2m + 30

T = 40

substitute for T

2m + 30 = 40

2m = 10

m = 5

2) A = 4bc

A = 100

b = 2

100 = 4(2)c

100 = 8c

c = 12.5

Answer:

0.25±0.095

Step-by-step explanation:

sample size n= 80

z*=1.96

p^± sqr(p^(1-p^)/n)

=0.095

Step-by-step explanation:

The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is 0.25 +0.080.

Fatimah wants to estimate the proportion of students at her school who ate breakfast every day last week.

She takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.

Based on this sample, which of the following is a 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week?

She takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.

[tex]\rm P = \dfrac{Sample \ space}{Total \ SRS}\\ \\ P = \dfrac{20}{80}\\ \\ P = \dfrac{1}{4}\\ \\ P = 0.25[/tex]

Therefore,

The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is

=[tex] = 1.96 \times \sqrt{\dfrac{0.25(1-0.25)}{80}}\\ \\ = 1.96 \times \sqrt{\dfrac{0.25\times 0.75}{80}}\\\\ = 1.96 \times 0.40\\\\ = 0.080[/tex]

Hence, The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is 0.25 +0.080.
