Answer:
Number of cheesecakes local bakery expects to sell in a day = 14 (Approx.)
Step-by-step explanation:
Given:
Number sold Probability xP(x)
0 0.1 0
5 0.19 0.95
10 0.05 0.5
15 0.14 2.1
20 0.52 10.4
Find:
Number of cheesecakes local bakery expects to sell in a day
Computation:
Number of cheesecakes local bakery expects to sell in a day = Sum of xP(x)
Number of cheesecakes local bakery expects to sell in a day = 0 + 0.95 + 0.5 + 2.1 + 10.4
Number of cheesecakes local bakery expects to sell in a day = 13.95
Number of cheesecakes local bakery expects to sell in a day = 14 (Approx.)

Aaron bought 7 packs of balloons for the party. There were 50 balloons in each bag. 40 of the total number of balloons were yellow. How many balloons were not yellow?
Answer:
[tex]total \: balloons = (50 \times 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons[/tex]
Answer:
310
Step-by-step explanation:
The equation that we would use to solve this problem is 7 × 50 - 40 = b
(b is the number of non-yellow balloons)
Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.
7 × 50 = 350.
Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.
350 - 40 = 310

An experimenter conducted a study of the relation of size in a particular species of bird to behavioral displays of dominance. The results for the first four birds observed were as follows:
Bird Size: 14 18 14 10
Bird Behavior: 74 82 74 70
Required:
a. Change the variable names to Bird Size and Bird Behavior
b. Make a scatter plot.
c. Compute the correlation
Answer:
Scatterplot is attached below
Correlation Coefficient = 0.0973
Step-by-step explanation:
Bird Size: 14 18 14 10
Bird Behavior: 74 82 74 70
The Correlation Coefficient, R = 0.973 ; which gives a very strong positive correlation between variable, x bird size and y, Bird Behavior.
Which equation represents the relationship between X and Y shown in the table?
Answer:
y= 2x-3
Step-by-step explanation:
to find the slope you use rise over run to get 2. to check to see the correct equation replace x with any of the x values in the chart and if you get the same y values as the chart then your equation is correct.
Find the lateral and surface area of the figure.
Answer:
A.
Lateral area (LA) = 324 cm²
Surface area = 432 cm²
Step-by-step explanation:
✔️Lateral area of the triangular prism = perimeter of the base (P) × height of prism (L)
Perimeter (P) = 9 + 12 + 15
Perimeter (P) = 36 cm
height of prism (L) = 9 cm
Lateral area (LA) = 36 × 9 = 324 cm²
✔️Surface area = bh + LA
b = 9 cm
h = 12 cm
LA = 324 cm²
Surface area = 9*12 + 324
= 108 + 324
Surface area = 432 cm²

A point is chosen at random in the circle.
What percent of the time will the point be in
the square?
Round to the nearest tenth of a percent.
1 in.
[ ? ]%
Enter
Answer:
78.5%
Step-by-step explanation:
the percent of time the point will land in the square can be determined by dividing the area of the square by the area of the circle
A(circle) = 3.14(1)²
A(circle) = 3.14
A(square) = side squared
if radius of square is 1 inch then each side is 2 inches
A(square) = 2²
A(square) = 4 inches
3.14/4 = 78.5%

Step-by-step explanation:
20 men can complete a piece of work in 24 days how many men should be subtracted to finish the work in 32 days?
Answer:
5 men should be subtracted.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.
How many men should be working to complete the work in 32 days?
20 men - 24 days
x men - 32 days
Then
[tex]32x = 20*24[/tex]
[tex]x = \frac{20*24}{32}[/tex]
[tex]x = 15[/tex]
How many men should be subtracted?
There are 20 to complete in 24 days.
15 are needed to complete in 32 days.
20 - 15 = 5
5 men should be subtracted.

In the following triangle, find the values of the angles Band B, which are the best approximations to the solutions to this ambiguous case?
Answer:
B. B = 70.5° or B' = 109.5°
Step-by-step explanation:
(sin 45°)/13.5 = (sin B)/18
sin B = (18 * sin 45°)/13.5
sin B = 0.9428
B = sin^-1 0.9428
B = 70.5°
B' = 180° - 70.5°
B' = 109.5°
idhi has cut out a semi-circular piece from a plastic sheet and divided it into 8 equal parts as shown: She wants to use this to measure angles. Which of the following angles will she be able to measure accurately using this semi-circular piece?
a. 30⁰
b. 45⁰
c. 60⁰
d. 100⁰
Answer:
[tex]c)\ 45^\circ[/tex]
Step-by-step explanation:
Given
A semicircle divided into 8 parts
Required
Angle that can be measured with the piece
First, we calculate the minimum angle that can be calculated.
[tex]\theta =\frac{Semi\ circle}{8}[/tex]
[tex]Semicircle = 180^\circ[/tex]
So, we have:
[tex]\theta =\frac{180^\circ}{8}[/tex]
[tex]\theta =22.5^\circ[/tex]
This implies that all angles that can be measured using the piece must be a multiple of 22.5 not greater than 180 degrees (i.e. not greater than the semicircle)
So, we have:
[tex]\theta =22.5^\circ,\ 45^\circ,\ 67.5^\circ,\ 90^\circ,\ 112.5^\circ,\ 135^\circ,\ 157.5^\circ,\ 180^\circ[/tex]
From the list of options, only 45 degrees appear in the possible values of [tex]\theta[/tex]
Hence:
[tex]\theta = 45^\circ[/tex]
