Answer:
Height is 1 1/24 unit.
Step-by-step explanation:
Given:
volume = 5/24 unit³
base area = 1/5 unit²
Rectangular prism:
volume = length * width * height
base area = length * width
Volume = base area * height
height = volume / base area
h = 5/24 ÷ 1/5
h = 5/24 * 5/1 = 5*5 /24*1 = 25/24 = 1 1/24 unit

A shoe store donated a percent of every sale to hospitals. The total sales were $8900 so the store donated $356. What percent of $8900 was donated
Answer:
4%
Step-by-step explanation:
Given data
The total sales= $8900
Donated amount=$356
Hence the percent donated is
=Donated amount/Total Sales *100
= 356/8900*100
=0.04*100
=4%
Hence the donated percent is 4%
En un parque de forma circular de 700 m de radio hay situada una fuente,
tambien de forma circular, de 5 m de radio. Calcula el área de la zona de
paseo.
área del parque
A=Pi . R^2
A=Pi (700m^2)
A=3.1416 x 490000m^2
A= 1539380.4 m ^2
área de la fuente
a= Pi. r^2
a=Pi (5cm^2)
a=3.1416 x 25cm^2
a= 78.54 cm^2
Luego lo que hacemos que al area grande le restamos la pequeña.
pero antes que nada convertiremos los metros a centimetros.
A= 1539380.4 m^2
1539380.4 m^2 (100cm/1m)
eliminaras los metros y te quedara asi
1539380.4 ( 100 cm/ 1)
153,938,040 cm^2
luego restamos A-a
153,938,040 cm^2 - 78.54cm^2
R/ el area de la zona de paseo es de 153937961.5 cm^2 !!

Look at the Example. How do you know that (-3/4)(-8a)+(-3/4)(-12) is equivalent to both -3/4(-8a-12) and 6a+9?
PLEASE HELP I WILL GIVE BRAINLIEST.
Step-by-step explanation:
To solve the problem [tex]-\frac{3}{4} (-8a-12)[/tex]
we first use the distributive property, which means to multiply everything on the inside with the outside number on the left.
so [tex]-\frac{3}{4} * -8a, -\frac{3}{4} *-12[/tex]
This would equal
[tex]6a+9[/tex]
its pretty simple.
what may be confusing is the fraciton multiplication
to solve this we convert the -8 and -12 into a fraction. This would be
[tex]-\frac{8}{1} and-\frac{12}{1}[/tex]
and multiplying fractions is easy, u just do it straight across.
so 3 times 8 is 24 so this would be 24/4
and 24/4 simplified is 6
and 3 times 12 is 36
so it would be 36/4
this would equal 9 simplified
and since we are just multiplying all negative numbers here they all turn out to be positive numbers because you should know. a negative times a negative equals a positive.
11. One term, about 700 Statistics 2 students at the University of California, Berkeley, were asked how many college mathematics courses they had taken, other than Statistics 2. The average number of courses was about 1.1; the SD was about 1.5. Would the histogram for the data look like (i), (ii), or (iii)? Why?
Answer:
(i)
Step-by-step explanation:
Given that the mean value of the distribution is 1.1, then we can safely assume that the peak value will be reside around one with a variability measure, standard (1.5) represents changes in distribution away from the mean value. The could be to either side of the distribution. However, the cannot be a negative value for the number of courses taken, hence, the maximum value we can have to the left is 0. (figures to the far left of the distribution are negative). This means that the curve will fall towards the right, (positive direction hence giving a right skewed distribution.

Find the area of a circle with a circumference of 31.4 units.
Answer:
area = 78.46
Step-by-step explanation:
31.4 = 2pi * r
divide 31.4 by 2 and get 15.7
15.7 = pi * r
divide 15.7 by pi and get
4.997 = r
(4.997^2) * pi = 78.46

2. The mean weight of the students on the
Trail Middle School wrestling team is 150
pounds with a mean absolute deviation of
10 pounds. The mean weight of the
students on the Burlington Middle School
wrestling team is 130 pounds with a mean
absolute deviation of 10 pounds. By how
many pounds is the mean weight of the
students on Trail's team greater than the
mean weight of the students on
Burlington's team?
Answer:
The mean of Trail Middle School wrestling team is greater by 20 pounds as compared to that of Burlington Middle School wrestling team
Step-by-step explanation:
Since the value of absolute deviation in case of Trail Middle School wrestling team and Burlington Middle School wrestling team is same. Hence, there will be no impact of it while determining the difference in mean deviation of both the team.
Thus, the difference in mean deviation is [tex]150-130 = 20[/tex]
The mean of Trail Middle School wrestling team is greater by 20 pounds as compared to that of Burlington Middle School wrestling team

The set of life spans of an appliance is normally distributed with a mean Mu = 48 months and a standard deviation Sigma = 8 months. What is the z-score of an appliance that stopped working at 64 months?
Group of answer choices
-2

Answer:
D.2
Step-by-step explanation:
The z-score of an appliance that stopped working at 64 months is 2
What is z score?Standard score or z score in statistics is defined as the number of standard deviations by which that the value of a score is above or below the mean value.
The formula to find the z score of a data is,
z = (x - μ) / σ
Here x is the observed value, μ is the mean and σ is the standard deviation.
Given that,
Mean = 48 months
Standard deviation = 8 months
x = 64 months
Substituting in the formula,
z = (64 - 48) / 8 = 2
Hence the z score of the appliance is 2.

Step-by-step explanation:
m<A=m<B
Congruent angles and they are vertical angles. The other two are also the same because the angles given have the same degrees.
m<A is supplementary to 83 degrees
Supplementary angles are two angles that sum up to 180 degrees.
180-83=97
97 degrees is the answer for each missing angles.

Answer:
Boys: 2/17
Girls: 4/17
Step-by-step explanation:
2 + 15 = 17 (to get the total number of boys in Sapphire's class)
4 + 13 = 17 (to get the total number of girls in the class)
The proportion is how many who are left handed over the total number of girls/boys. ^^
So, left-handed for boys = 2, which makes the proportion 2/17
And there are 4 left-handed girls, so the proportion is 4/17

How many hamburgers were sold on Saturday?
Answer:
542
Step-by-step explanation:
I believe it is 542, because 596 and 54 are the only numbers available in this equation, so you would subtract 54 from 596
596-54=542
