The circle graph below shows the scores of the latest math test. It represents 32 students. Approximately how many students earned a B or higher on the math test? 32 20 8 12
Answer:
20
Step-by-step explanation:
The circle graph below shows the scores of the latest math test. It represents 32 students. The 12 students earned a B or higher on the math test.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b percent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
The circle graph below shows the scores of the latest math test. It represents 32 students.

An important problem in industry is shipment damage. A pottery producing company ships its product by truck and determines that it can meet its profit expectations if, on average, the number of damaged items per truckload is fewer than 11. A random sample of 19 departing truckloads is selected at the delivery point and the average number of damaged items per truckload is calculated to be 9.4 with a calculated sample of variance of 0.49. Select a 95% confidence interval for the true mean of damaged items.
Answer:
The 95% confidence interval for the mean is approximately;
(9.063, 9.737)
Step-by-step explanation:
The given parameters are;
The mean of the sample, [tex]\overline x[/tex] = 9.4
The sample variance, s² = 0.49
The sample size, n = 19
The confidence level = 95%
Therefore, we get;
[tex]CI=\bar{x}\pm t_{\alpha/2} \dfrac{s}{\sqrt{n}}[/tex]
The degrees of freedom, df = n - 1
∴ df = 19 - 1 = 18
From the t-table, the critical-t = 2.101
Therefore, we have;
[tex]CI=9.4\pm 2.101 \times \dfrac{\sqrt{0.49} }{\sqrt{19}}[/tex]
Therefore, we have;
9.4 - 2.101×√(0.49/19) < μ < 9.4 + 2.101×√(0.49/19)
9.0626 < μ < 9.737
∴ The 95% confidence interval for the mean ≈ (9.063, 9.737)

Answer:
551.8 feet
Step-by-step explanation:
We are given
Adjacent = 1300 feet
Opposite = x
Angle = 23°
We solve using the trigonometric function Tangent
tan θ = Opposite/Adjacent
tan 23 = x/1300 feet
Cross Multiply
x = tan 23 × 1300 feet
x = 551.81726107 feet
Approximately = 551.8 feet
The Length of the building = 551.8 feet
HELP ASAP TIMED!!!!!!!!!!!!!!!
Answer:
x = 12.3
y = 15.9
Step-by-step explanation:
Apply trigonometric ratio to find x and Reference angle = 51°
Opposite side length = x
Adjacent side length = 10
Hypotensive length = y
✔️To find x, apply TOA:
Tan 51° = Opp/Adj
Tan 51° = x/10
x = Tan 51° × 10
x = 12.3 (nearest tenth)
✔️To find y, apply CAH:
Cos 51° = Adj/Hyp
Cos 51° = 10/y
y × Cos 51° = 10
Divide both sides by Cos 51
y = 10/Cos 51
y = 15.9 (nearest tenth)

the first one is 2. we replace x with 2. now we have 1+3*2. We would have to multiply 3 and 2 which is 6. Now we have 1+6. which equals 7. Next one is 4 times 3 equals 12. 12 + 1 =13. Next one 6 times 3 equals 18. 18 + 1 = 19. The same thing for the next one
In a park, a sidewalk is built around the edge of a circular garden as shown. The sidewalk is 5 feet wide, and the garden measures 10 feet across. Which measurement is closest to the circumference of the outer edge of the sidewalk?
Answer:
63 feet.
Step-by-step explanation:
The total diameter of the circular garden is given by 5ft+ 10 ft + 5 ft= 20 feet
As the circumference of the circle = 2πr where r = radius obtained by dividing the diameter by 2. Here the diameter = 20 feet and r= d/2 = 20/2 = 10 feet
Putting the values in the circumference formula
Then C= 2(22/7) (10)= 62.85 feet
Rounding gives almost 63 feet .
The number of customers that come to a certain clothing store each day follows a normal distribution. The mean number of customers is 428, and the standard deviation is 32. What is the probability that more than 524 customers will come to the store on a given day?
A.
0.15%
B.
0.3%
C.
2.5%
D.
5%
Answer: the true answer is A
Step-by-step explanation:
Good luck, give Brainliest
Using the normal distribution, it is found that the probability that more than 524 customers will come to the store on a given day is given by:
A. 0.15%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 428, \sigma = 32[/tex].
The probability that more than 524 customers will come to the store on a given day is one subtracted by the p-value of Z when X = 524, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{524 - 428}{32}[/tex]
Z = 3
Z = 3 has a p-value of 0.9985.
1 - 0.9985 = 0.0015 = 0.15%.
Hence option A is correct.

If the surface areas of two spheres are in ratio 16:9, then their volumes will be in the ratio
Answer:
64 : 27
Step-by-step explanation:
If linear ratio is a : b , then
area ratio = a² : b²
volume ratio = a³ : b³
Given area ratio = 16 : 9 , then
linear ratio = [tex]\sqrt{16}[/tex] : [tex]\sqrt{9}[/tex] = 4 : 3
volume ratio = 4³ : 3³ = 64 : 27

Give two reasons why this shape is a square when x = 5.
(3x - 2)
(x + 8) cm
Step-by-step explanation:
If we put 5 in X we get:
1. 3x-2 = 3(5)-2 = 15-2 = 13
2. x+8 = 5+8 = 13
So: 3x-2=x+8.

Find the area of the following composite figure: A circle with a area of 50 inches, a rectangle with an area of 75 inches, and a square with an area of 20 inches. ***HINT: since we have the areas, all we have to do is add the areas of each shape to find the composite area.
Answer:
145 inches
Step-by-step explanation:
Area of the circle = 50 inches
Area of the rectangle = 75 inches
Area of the square = 20 inches
Composite area = Area of the circle + Area of the rectangle + Area of the square
= 50 inches + 75 inches + 20 inches
= 145 inches
Composite area = 145 inches
