Find the percent of the total area under the standard normal curve between the given z-scores. z= -1.10 and z= -0.36
To find the percent between two z-scores under the standard normal curve, subtract the individual areas. In this case, the percentage between z = -1.10 and z = -0.36 is 1.72%.
To find the percent of the total area under the standard normal curve between z-scores, you need to first calculate the difference between the two areas to the left of each z-score. Given that the area to the left of z = -1.10 is 0.3446 and the area to the left of z = -0.36 is 0.3618, you can find the percent between them by subtracting these values: 0.3618 - 0.3446 = 0.0172 or 1.72%.
After a car is purchased, the value of a new car decreases $4000 each year. After 3 years, the car is worth $18000.
Write an equation that represents the value V (in dollars) of the car x years after it is purchased.
Answer:
Original - 4000x
so, after 3 years we have:
Original - 12000 = 18000
=> Original = $30,000

Round 0.955 inches to the nearest tenth of an inch
The nearest tenth is the first digit after the decimal point. The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.
Given 0.995 inches
round to the nearest tenth of an inch.
This means round to the nearest first decimal point and to include the actual first decimal point (and that decimal point only, the tenth place).
We are given the number 0.955. This is given to the nearest thousands.
We examine the tenth place at 0.9.
So we know our choices are
What is the nearest tenth?The nearest tenth is the first digit after the decimal point.
0.9 (round down to the nearest tenths place) or 1.0 (round up to the nearest tenths place).
We examine the number 0.955 and look to the next value, the hundredths place
If that digit is 5 or greater we round up and the correct answer is 1.0.
If that number is 4 or less (i.e. 0 to 4), we round down and the correct answer is 0.9.
In the case of our give value: 0.955.
The digit to the right of 9 is 5 so, as previously mentioned,
we round up to 1.0.
Therefore, The round 0.955 inches to the nearest tenth of an inch is 1.0 inches.
The answer is 1.0 inches.

The height of four boys measured 152.0 cm. 150.75 cm,149.5 cm, and 149.25 cm. Bradley is the tallest, Calvin is taller than Josh, but shorter than Mark. Josh is the shortest. What is Mark's height
Answer:
150.75 cm
Step-by-step explanation:
Given heights,
152.0 cm, 150.75 cm, 149.5 cm, and 149.25,
∵ Calvin is taller than Josh, but shorter than Mark,
The increasing order of heights,
Josh < Calvin < Mark,
Also, Bradley is the tallest,
That is, the height of Bradley is the greater than Josh, Calvin and Mark,
So, the final increasing order of heights,
Josh < Calvin < Mark < Bradley
∵ 149.25 < 149.5 < 150.75 < 152.0
Hence, the height of Mark is 150.75.

At 2:30 am the temperature in Joelle is 3 F. The temperature drops 3/4 of a degree in 30 min. What is the temperature on Joelle at 3:00am?
Answer: B. [tex]=2.25^{\circ}F[/tex]
Step-by-step explanation:
Given: At 2:30 am the temperature in Joelle is 3 F.
The temperature drops 3/4 of a degree in 30 min.
3/4 of a degree= [tex]\frac{3}{4}\times1^{\circ}F=\frac{3}{4}=0.75^{\circ}F[/tex]
Therefore, the temperature on Joelle after 30 min= [tex]3^{\circ}F-\frac{3}{4}\ of\ 1^{\circ}F[/tex]
[tex]=3^{\circ}F-0.75^{\circ}F[/tex]
[tex]=2.25^{\circ}F[/tex]
Thus, the temperature on Joelle at 3:00am=[tex]=2.25^{\circ}F[/tex]

Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4). Include your work in your final answer.
Answer:
y-5=-1/2(x+3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-5)/(-1-(-3))
m=-1/(-1+3)
m=-1/2
y-y1=m(x-x1)
y-5=-1/2(x-(-3))
y-5=-1/2(x+3)

B. 1521 in.
C. 78 in
D. 156 in
The circumference of the circle with radius [tex] r [/tex] is given by [tex] P=2\pi r [/tex]. When [tex] r=39\;in [/tex],
[tex] P=2\pi (39)\\
P=78\pi \;in [/tex]
Correct choice is (C).
Answer:
Option C is correct
78 π inches
Step-by-step explanation:
Circumference (C) of a circle is given by:
[tex]C = 2 \pi r[/tex] .....[1]
where, r is the radius of the circle.
As per the statement:
From the given figure;
radius of the circle(r) = 39 in.
Substitute this value in [1] we have;
[tex]C = 2 \cdot \pi \cdot 39 = 78 \pi[/tex]
Therefore, the value of circumference of the circle in terms of pi is, [tex]78 \pi in.[/tex]

Sam wants to know how long it will take to fill his baby pool that holds 24 gallons. After 1 minute, there are 2 gallons of water in the pool. He plots the points (0,0) and (1,2) on his coordinate plane. What is the x-value of the point (x, 24)?
Answer:
(12,24)Step-by-step explanation:
Givens
The pool holds 24 gallons.The rate is 2 gallons of water per minute.The line that represents the problem passes through points (0,0) and (1,2).We can deduct the equation that represents this problem using the point-slope formula
[tex]y-y_{1} =m(x-x_{1} )\\y-2=2(x-1)\\y=2x-2+2\\y=2x[/tex]
So, for [tex]y=24[/tex], we have
[tex]y=2x\\24=2x\\x=\frac{24}{2}\\ x=12[/tex]
Therefore, after 12 minutes there were 24 gallons of water in the pool. The right answer is (12,24).

Melanie prepared 7 1/2 tablespoons of her spice mixture she is 1/4 tablespoon to make a batch of barbecue sauce estimate the number of batches of barbecue sauce she can make by using the spice mixture
Answer: There are 30 batches of barbeque sauce that she can make by using the spice mixture.
Step-by-step explanation:
Since we have given that
Number of tablespoons of her spice mixture = [tex]7\dfrac{1}{2}=\dfrac{15}{2}[/tex]
Number of tablespoons to make a batch of barbeque sauce = [tex]\dfrac{1}{4}[/tex]
so, the number of batches of barbeque sauce would be
