Answer:
8.5
Step-by-step explanation:
The median of the data in the dot plot for the score for each student in Mrs. Baker's class is 8.5.
What is the median of a data set?The median of the data is the middle value of the data set when it arrange in ascending or descending order.
The dot plot for the Mrs. Baker's class is is shown in the figure attached below.
In the increasing order, the data of the image is arranged below.
0,1,5,7,8,8,9,9,9,10,10,10
There are total 12 values in the is data which is even. The middle term is 8 and 9 in the arranged data. For the even values, the median is the average of both the values.
[tex]m=\dfrac{8+9}{2}\\m=8.5[/tex]
Thus, the median of the data in the dot plot for the score for each student in Mrs. Baker's class is 8.5.

The volume of a sphere is 5000pi m^3 What is the surface area of the sphere to the nearest square meter?
Answer:
2nd chioce
Step-by-step explanation:
The formula = () − applies to the demand of a product, where q is the number of units and P is the price of one unit. How many units will be demanded if the price is Rs. 18.00?
Answer:
4320 units quantities were demanded
Step-by-step explanation:
Given:
[tex]p = 90 (5) - \frac{q}{10}[/tex]
Required:
The units demanded when price = 18.00
This implies that:
[tex]p = 18.00[/tex]
So, we have:
[tex]p = 90 (5) - \frac{q}{10}[/tex]
[tex]18.00 = 90(5) - \frac{q}{10}[/tex]
Open bracket
[tex]18.00 = 450 - \frac{q}{10}[/tex]
Collect like terms
[tex]\frac{q}{10} = 450 - 18.00[/tex]
[tex]\frac{q}{10} = 432[/tex]
Solve for q
[tex]q = 432 *10[/tex]
[tex]q = 4320[/tex]

Use a formula to find the amount of wrapping paper you need to wrap a gift in the cylindrical box shown. You need to cover the top, bottom, and all the way around the box. Use 3.14 for .
Answer:
Total wrapping paper need = 960.84 inch²
Step-by-step explanation:
Given:
Height of cylinder box = 8 inch
Radius of cylinder box = 9 inch
Find:
Total wrapping paper need
Computation:
Total wrapping paper need = Total surface area of cylinder
Total surface area of cylinder = 2πr(h + r)
Total wrapping paper need = 2[3.14][9][8+9]
Total wrapping paper need = 2[3.14][9][17]
Total wrapping paper need = [6.28][9][17]
Total wrapping paper need = [56.52][17]
Total wrapping paper need = 960.84 inch²

If events A and B are independent, P(A) = 0.62, and P(
BA) = 0.93, what is P(B)?
O 0.41
O 0.93
O None of the other answers are correct
O 0.58
O 0.67
Answer:
Step-by-step explanation:
you’re given A=0.62 and B/A=0.93
you’re solving for B
substitute your A value of 0.62
B/0.62=0.93
same as B/0.62=0.93/1
now cross multiply
B= 0.62x0.93
B=0.5766
B=0.58
Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?
A) h(x) = 3x + 4
B) h(x) = -3x + 4
C) h(x) = 3x-4
D) h(x) = -3x+4
Answer:
B. h(x) = -3x + 4.
Step-by-step explanation:
I am assuming that the vertical shift is upwards,
A refection in the x axis gives -3x
Vertical shift upwards of 4 gives -3x + 4.

Question 1 options:
A 30°-60°-90° triangle has a shorter leg with a length of 14 cm. The hypotenuse of the triangle is ___ cm
From now on, remember that the smallest side in a triangle is always facing the smallest angle of the triangle.
_________________________________
The question told us that the shorter leg has a measure of 14 in which it is tha smallest side of the triangle thus 14 is the facing side to the 30 degrees angle .
As we know, in a right-angled triangle, the facing side to the angle of 30 degrees has half measure of hypotenuse. So :
1/2 × hypotenuse = 14
Multiply both sides by 2
hypotenuse = 28

Answer:
Step-by-step explanation:
use pythageran theorem
c=square root of a2+b2
but we are solving angle b
so
b2=c2-a2
b2=225-196
b2=29
b approximately = 5.39 Rounded up
Answer:
5.4
Step-by-step explanation:
c² = a² + b²
15² = 14² + b²
225 = 196 + b²
b² = 225 - 196
b² = 29
b = 5.4

A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Answer:
10344.827586 basketballs
Step-by-step explanation:
A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Step 1
We find the volume of the room
The room is rectangular in shape
Volume = Length × Width × Height
= 15ft × 20ft × 10ft
= 3000ft³
Step 2
Basket ball is spherical in shape
Volume of a sphere = 4/3πr³
Diameter = 9.6 inches
Radius = Diameter/2 = 9.6 /2 = 4.8 inches
Convert Radius from inches to ft
= 4.8inches/12
= 0.408333 feet
Volume of a sphere = 4/3 × π × 0.408333³
= 0.29 ft³
Step 3
3000 ÷ 0.29
10344.827586
