Darius filled up his gas tank with 24 gallons of gas. For each mile that he drives, he uses 0.06 gallons of gas. How may gallons of gas are left in the tank after driving 240 miles?

Step-by-step explanation:

Confidence interval is:

CI = x ± CV · SE

where x is the mean, CV is the critical value, and SE is the standard error.

There is no difference between the population means, so x = 0.

The confidence level is 95%, so CV = 1.96.

SE = 0.69.

So the confidence interval is:

CI = 0 ± (1.96) (0.69)

CI = (-1.35, 1.35)

1.74 is outside of the confidence interval, so it is statistically significant.

Answer:

5/6 and -26/5

Step-by-step explanation:

-16 divide -2 = 8

Add 8 = 16

Remove absolute value

Positive 16 - 10 = 6

Divide 5 = 6/5

Negative -16 - 10 = -26

Divide 5 = -26/5

Step-by-step explanation:

I think it's a I am not sure

Answer:

(i) False. Let A = 30° and B = 60°, then sin (A + B) = sin (30° + 60°) = sin 90° = 1 and, sin A + sin B = sin 30° + sin 60° = 1/2 + √3/2 = 1+√3/2(ii) True. sin 0° = 0 sin 30° = 1/2 sin 45° = 1/√2 sin 60° = √3/2 sin  90° = 1 Thus the value of sin θ increases as θ increases.(iii) False. cos 0° = 1 cos 30° = √3/2 cos 45° = 1/√2 cos 60° = 1/2 cos 90° = 0 Thus the value of cos θ decreases as θ increases.(iv) True. cot A = cos A/sin A cot 0° = cos 0°/sin 0° = 1/0 = undefined.

She was driving 51 miles per hour.

Step-by-step explanation:

51 x 4 = 204

204 / 4 = 51

Answer:

0.12

Step-by-step explanation:

This is the answer because:

1) First, rewrite the expression including the x value

1.2(0.1)

2) Next, we know 1.2 x 1 is 1.2, but since we have one decimal point in 0.1, we have to move the decimal point in 1.2 once to the left. This will make the answer 0.12

Answer: Height = 14

Step-by-step explanation: 10.5 / 0.75 = 14

Answer:

The height is 14 inches

Answer:

It is $1.50 or $18 per dozen tennis balls

Step-by-step explanation:

1. Divide the total price by the number of tennis balls.

36/24= 1.50

So it cost $1.50 per tennis ball.

2. Then solve by dividing the total price by the number of tennis balls:

36/2= $18

"So it cost $18 per dozen tennis balls"

It is $1.50 or $18 per dozen tennis balls

Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the mean is above or below the raw score. If the z score is positive then the raw score is above the mean while if the z score is negative then the raw score is below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}\\ \\\mu=mean, \sigma=standard\ deviation[/tex]

a)

From the normal distribution, 0.5 corresponds to a z score of 0.

z = 0.

b) From the normal distribution, an area of 0.9826 to the left corresponds to a z score of 2.11.

c) An area to the right of 0.1423 = an area of 0.8577 ( 1- 0.1423) to the left.  From the normal distribution, an area of 0.8577 to the left corresponds to a z score of 1.07

This value is approximate because we used the approximation pi = 3.14

=================================================

Explanation:

For problems like this, a common approach is to break the figure into smaller pieces. Find the area of each small piece, then add up those individual areas to get the full area we're after.

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

A = area of triangle

A = 0.5*base*height

A = 0.5*6*8

A = 24 square feet

-----------

B = area of the semicircle with radius r

B = 0.5*(area of full circle with radius r)

B = 0.5*(pi*r^2)

B = 0.5*pi*r^2

B = 0.5*3.14*4^2 .... the diameter is 8, radius is half that

B = 25.12  square feet

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

C = area of the full figure

C = A+B

C = 24+25.12

C = 49.12 square feet

Answer:

7 ft per in

Step-by-step explanation:

If she has a scale where 49 feet is represented by 7 inches, then the ratio is:

49 feet to 7 inches  which can be written as:49 ft /7 in = 7 ft / in

So the scale is 7 feet per inch

Answer:

2x + 3 = 15

x = 6

2(6) + 3 = 15

Step-by-step explanation:

This is the answer because:

1) 2 x 6 = 12, 12 + 3 = 15

2) 2 + 6 + 3 = 11

Therefore, the answer is 2(6) + 3 = 15

Hope this helps!

Answer:

x=6

Step-by-step explanation:

2x+3=15

15-3=12

12/2=6

x=6

Answer:

[tex]y = \frac{4}{3}x[/tex]

Step-by-step explanation:

Given:

Variation: Direct Variation.

This can be represented as:

[tex]y\ \alpha\ x[/tex]

[tex]y = 16; x = 12[/tex]

Required

Write out the equation

First, the variation has to be converted to an equation

[tex]y\ \alpha\ x[/tex]

[tex]y = kx[/tex]

Where k represents constant of variation.

Substitute 16 for y and 12 for x

[tex]16 = k * 12[/tex]

Solve for k

[tex]k = \frac{16}{12}[/tex]

[tex]k = \frac{4}{3}[/tex]

To get the equation, we simply substitute 4/3 for k in [tex]y = kx[/tex]

[tex]y = \frac{4}{3}x[/tex]

Answer:

quotient less than the dividend​

Step-by-step explanation:

In this equation:

Dividend = 3/5

Divisor = 3 and

Quotient = 1/5

The question asks you to compare 3/5 to 1/5 and 3/5 is larger therefore the quotient less than the dividend​.
