When Sally went bowling, her average scores were 108, 72, and 95 If she bowls a 4th game, what will her score need to be to give her and average of 91?


Pls hurry! I need a full explanation!!

Answers

Answer 1

An average is the sum of the scores divided by the number of games played.

For her average to be 91 after 4 games the total of the scores needs to be 91 x 4 = 364

To find what her 4th score needs to be subtract her first 3 scores from 364

364 - 108 - 72 - 95 = 89

Her 4th game needs to be 89

Answer 2
Her score will need to be 89

Step-by-step explanation:

8x (the babysitter gets paid 8 dollars an hour, and x represents number of hours)

3 (this is the additional tip the babysitter gets; it's not dependent on the number of hours she/he works)

The babysitter will get paid the same despite babysitting two kids- no variable here is dependent on the amount of kids the babysitter babysits.

Answer:

A) 8x + 3

Step-by-step explanation:

The babysitter gets 8 dollars per hours, and x is the hours, so 8x, 8 dollars per hour. She also gets 3 dollars if she gets the children to sleep on time, so add 3. The equation is 8x + 3.

Mr. Mendel likes breeding different flowers in his garden. He noticed that when he breeds a white flower with a purple flower, most of the offspring are purple. To check that, he bred them again and obtained 181818 offspring, and 151515 of them were purple. Let's test the hypothesis that the offspring have equal chances of 50\%50%50, percent of being either white or purple versus the alternative that the chance of a purple offspring is greater. The table below sums up the results of 100010001000 simulations, each simulating 181818 offspring with a 50\%50%50, percent chance of being white or purple. According to the simulations, what is the probability of having 151515 purple offspring or more out of 181818? \qquad Let's agree that if the observed outcome has a probability less than 1\%1%1, percent under the tested hypothesis, we will reject the hypothesis. What should we conclude regarding the hypothesis? Choose 1 answer: Choose 1 answer: (Choice A) A We cannot reject the hypothesis.

What is blended inheritance?

Blended inheritance is a form of inheritance which combines characteristics from both parents. It occurs when the genetic contribution from each parent is not distinct, and instead, the traits of both parents are combined in the offspring. It is also known as "mosaic inheritance" or "mixed inheritance". It can occur in both plants and animals. Blended inheritance is different from Mendelian inheritance, which involves the segregation of individual traits from each parent.

here, we have,

This result showed that the traits for flower color were inherited in a non-blended manner, with one dominant trait (purple flower color) masking the recessive trait (white flower color).This experiment contradicts the idea of blended inheritance, which states that the traits of offspring are a blend of the traits of the parents. Mendel’s experiments showed that traits were passed on in a discrete and non-blended manner, with the dominant trait being fully expressed in the offspring and the recessive trait not being expressed at all.

Therefore, purple flowers are obtained when Mendel cross-pollinated.

Raven is baking cookies. It takes 15 of an hour to bake each pan of cookies, and she can only fit 1 pan of cookies at a time in the oven. How many pans of cookies can she bake in 2 hours? Write and solve an equation to represent this problem.

Answers

Answer:

she can put 8 pans in the oven in 2 hours.

Step-by-step explanation:

there is 120 minutes in 2 hours. 120 ÷ 15 = 8. so then the 8 equals how many pans she can put in the oven

she can put 8 pans in the oven in the time span of 2 hours.

step by step:
15min/1hr = 1 pan
15 x 4 = 60 (1 hour)
multiply 4 by two (for two hours)
4 x 2 = 8

Answer: A


Explanation: if you combine like terms (first do the x’s, so 7x, 9x, 9x)
7x + 9x + 9x
25
(Then you combine the second like terms, -3, -3, -4)
-3 - 3 - 4

Explain how to decompose a triangle into congruent triangles. How does the area of those decomposed triangles relate to the area of the rectangle?

Answers

So for any triangle, you can divide it into four congruent triangles by connecting the midpoints of each side. You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

What is the area of the shaded region?

Answer:

if pi is 3.14: 163.52 [tex]m^2[/tex]

if pi is just π: 264 - 32π [tex]m^2[/tex]

Step-by-step explanation:

22 x 12 = 264

4 x 4 = 16

16 x 2 = 32

16 x 3.14 = 50.24

264 - 50.24 x 2 = 163.52

Answer:

163.47

Step-by-step explanation:

We know the area of the whole rectangle by multiplying 12 by 22 to get 264. Now we just have to find the area of the circles and subtract it from the rectangle.

The area of a circle is πr^2. These circles' radii is 4, so 4^2π = 16π

Since there are 2 circles, double 16π to get 32π, 32π is equal to 100.53096491, rounded to 100.531. 264 - 100.531 = 163.469, rounded to 163.47
