Work out the ages of Ayesha, Bennie and Chloe.

Answers

Answer 1


Answer: Ayesha = 9. Bennie = 16. Chloe = 32
Explanation: (A stands for Ayesha, B stands for Bennie and C stands for Chloe) B = A + 7
C = 2(A + 7)
A + A + 7 + 2(A+7) = 57
A + A + 7 + 2A + 14 = 57
4A + 21 = 57
4A = 36
A= 9

Answers

Answer:

Step-by-step explanation:

Given is an isosceles triangle,

Measures of base angles of an isosceles triangle are equal.

Therefore,

Measure of central angle

= 180° - ( 76° + 76°)

= 180° - 152°

= 28°

Measure of shaded angle

= 360° - 28°

= 332°

In a quiz contest, Mary answers 90% of the questions correctly without any additional clues from the quiz coordinator. The randomly generated numbers below simulate this situation.

The numbers 0 to 8 represent questions answered correctly without additional clues, and the number 9 represents questions that needed additional clues.

44 51 99 66 23
68 72 20 20 59

99 10 55 10 35
36 78 92 37 96
The estimated probability that it would take at least three questions for Mary to need additional clues is (_____)

The estimated probability that Mary needed additional clues to answer two consecutive questions is (_____)

Answers

To solve this problem, we should note that there are:

total questions = 100

questions answered correctly = 90

questions that needed additional clues = 10

1. The first question is to find the probability that in the third question, Mary would need additional clue. Therefore this implies that in the first and second questions, Mary would answer it correctly. Therefore:

Probability = (question 1 answered correctly) * (question 2 answered correctly) * (question 3 needed clue)

Probability = (90/100)*(89/99)*(10/98)

Probability = 0.08256 = 8.26%

2. The second question finds for the probability that two consecutive needs additional clue, therefore:

Probability = (question 1 needed clue) * (question 2 needed clue)

Probability = (10/100)*(9/99)

Probability = 9.1*10^-3 = 0.91%

Answer:

1. The estimated probability that it would take at least three questions for Mary to need additional clues is 0.24

2. The estimated probability that Mary needed additional clues to answer two consecutive questions is 0.06

A triangle has an area of 230.86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?

I'll give brainlist!! Pls help

Answers

Answer:

Length of the base of the triangle = 19.37 inch (Approx.)

Step-by-step explanation:

Given:

Area of given triangle = 230.56 square inches

Height of the triangle = 23.8 inches

Find:

Length of the base of the triangle

Computation:

Area of triangle = (1/2)(b)(h)

Area of given triangle = (1/2)(Length of the base of the triangle)(Height of the triangle)

230.56 = (1/2)(Length of the base of the triangle)(23.8)

461.12 = (Length of the base of the triangle)(23.8)

(Length of the base of the triangle)(23.8) = 461.12

Length of the base of the triangle = 19.37 inch (Approx.)

Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find each probability

Answers

Complete question is;

Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find the probability that a randomly selected student scored less than 218.

Answer:

0.93

Step-by-step explanation:

We are given;

Mean; μ = 200

Standard deviation; σ = 12

Random value; x¯ = 218

Z-score formula is;

z = (x¯ - μ)/σ

z = (218 - 200)/12

z = 18/12

z = 1.5

From z-table, attached, probability = 0.93

Step-by-step explanation:

To find x we have to basically do pythagoream theorem twice. Both the traingles share the same long side. The find the long side of the top traingle do, [tex]a^{2} +16^{2} =25^{2}[/tex], and we find the long side to be [tex]\sqrt{369}[/tex]. Using this we now plug it into the pythagoream theorem for the bottom triangle. [tex]\sqrt{369} ^{2} +x^{2} =22^{2}[/tex], and doing this out we find that x=[tex]\sqrt{115}[/tex] or about 10.7.

In one sentence summarize this passage. The truth about pigs is that their reputation for being dull and dirty is undeserved. The pig is actually a curious and intelligent animal. For instance, a pig will not take anything for granted; it will poke, and prod something until it arrives at a conclusion. A pigs intelligence is so keen that the animal needs to do something only once such as turn on an automatic drinking fountain to know how to do it again. Furthermore, pigs are basically no dirtier than any other farm animal. Because pigs dont sweat, they seek out water in order to cool off. On a farm, the water that a pig finds is usually in a mud puddle. However, the pig would be just as happy splashing in a bathtub since it is water, not dirt that pigs enjoy. look at pic 10 pts will mark brainilest [GT.03]A majority of scientists worldwide agree with a new theory of evolution proposed by a group of students.
