The correct answer would be 30%
Hope this helps!
Mark me brainliest if I'm right :)
The required percentage of the class to receive by A or a B is 40%. Option D is correct.
What is the percentage?A percentage is a number or ratio expressed as a fraction of 100. It represents a proportion or share of a whole that is divided into 100 equal parts. Percentages are often used to express changes, comparisons, or proportions in various fields such as finance, economics, and statistics.
Following the table,
The total tally is = 30
Total tally of A or B = 7 + 5 = 12
The percentage of A or B in the tally is given as,
= 12/30 * 100%
= 40%
Thus, the required percentage of the class to receive by A or a B is 40%. Option D is correct.

Two dice, a red and a blue, are rolled. Find the probability that both dice show sixes
Answers
Answer:
2.78%
Step-by-step explanation:
So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.

Given P(A)=0.64P(A)=0.64, P(B)=0.4P(B)=0.4 and P(A\cap B)=0.356P(A∩B)=0.356, find the value of P(A\cup B)P(A∪B), rounding to the nearest thousandth, if necessary.
Answers
Answer:
Step-by-step explanation:
P(A U B) = P (A) + P (B) - P (A and B)
= 0.64 + 0.4 - 0.356
= 0.684
The value of P(A∪B) is 0.684
What is probability?Probabilities are used to determine the chances of events
The given parameters are:
P(A)=0.64,
P(B)=0.4
P(A∩B)=0.356
To find the value of P(A∪B), we make use of the following formula
P(A∪B) = P(A) + P(B) - P(A∩B)
So, we have:
P(A∪B) = 0.64 + 0.4 - 0.356
Evaluate the expression
P(A∪B) = 0.684
Hence, the value of P(A∪B) is 0.684

15.92 = LA2
sqrt 15.92 = LA
So, LA= 3.98 cm
LS: a2 + b2 = c2
(3.98)2 + (b)2 = (6.93)2
b = sqrt (6.93)2 - (3.98)2

Create a histogram of this data.
To create a histogram, hover over each age range on the x-axis. Then click and drag up to plot the data.
Answers
Answer:
Refer to image
Step-by-step explanation:
When creating a histogram it is best to create a range for the different variables that are available.
So for the sake of covering all the possible ranges from 1 - 22, let's divide it into 5 categories.
0 - 5
6 - 10
11 - 15
16 - 20
21 - 25
Now that we have set ranges for the different variables, we then find the frequencies.
0 - 5 : 3
6 - 10 : 2
11 - 15 : 3
16 - 20 : 1
21 - 25 : 3
Now that we have all the values we can then create our histogram

x= 8
Step-by-step explanation:
Half of a circle or a straight line is equal an angle of 180 degrees. Therefore, both the measurements of angles RPS and QPR are equal to 180 degrees.
3x + 12 + 7x + 88 = 180
Add like terms
10x + 100 = 180
-100. -100
10x = 80
/10. /10
x = 8
The angles combined should be 180
So, 180= 10x +100
Subtract 100 from both sides to cancel it out
80= 10x
Divide by 10 on both sides
8 = X
