Janet can make 1/2 of a necklace in 20 minutes. At this rate, how many necklaces can Janet make in 2 hours?

Answers

Answer:

3 necklaces

Step-by-step explanation:

2 hours = 120 minutes

1 necklace in 40 minutes

120/40 = 3

3 necklaces

Answer:

3 necklaces

Step-by-step explanation:

2 hours needs to be in the same units as the 20 minutes

2 hours = 2 * 60 minute = 120 minutes

Now we can use ratios to solve

1/2 necklace           x necklaces

-------------------- = ----------------

20 minutes              120 minutes

Using cross products

1/2 * 120 = 20x

60 = 20x

Divide by 20

60/20 = 20x/20

A movie theater is giving snack coupons with every ticket that is purchased. The table shows the type of snack coupon that was requested by 25 randomly selected customers during one day. Based on the date from the table, how many soda coupons will most likely be requested when 450 tickets are purchased? no links :(

Answers

Answer:

180

Step-by-step explanation:

[tex]\frac{10}{25\\}[/tex] = [tex]\frac{180}{450}[/tex]

It is mostly likely that 80 soda coupons will be requested when 450 tickets are purchased.

What is probability?

A number that reflects the chance.

From the table, we can see that out of 25 randomly selected customers, 10 requested a soda coupon.

The number of soda coupons that will most likely be requested when 450 tickets are purchased, we need to analyze the data in the table and calculate the probability of requesting a soda coupon.

Multiply the probability of requesting a soda coupon (0.4) by the number of tickets purchased (450): 0.4 * 450 = 180.

Therefore, it is most likely that 180 soda coupons will be requested when 450 tickets are purchased.

Step-by-step explanation:

PSR and PQR are right triangles.

First, you can find PR using the Pythagorean theorem.

[tex]PR = \sqrt{24^2+7^2} =\sqrt{625} = 25 cm[/tex]

Now let's do the same thing for the other triangle:

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

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

Her score will need to be 89

Here is a hanger that is in balance. We don’t know how much any of its shapes weigh. How could you change the number of shapes on it, but keep it in balance? Describe in words or draw a new diagram.

Answers

We can take away the two circles from both sides. We don't know the weight of each circle, but we know that the circles on each side balance each other out. Meaning that taking away those circles does not change the balance. Similarly, we can take away two squares from each side to keep things balanced as well.

After those subtractions, we're left with 2 squares on the left side and nothing else. On the right side, we have 4 triangles only.

2 squares balance with 4 triangles, which must mean 1 square balances with 2 triangles (divide both values by 2).

If you add a square to one side, you must add 2 triangles to the other side to keep things balanced.

-----------------------

Going back to the original diagram, we can have the following on the left side

2 circles4 squares2 triangles .... this is what we add

And on the right side we would have

2 circles3 squares  ... two squares initially but we added 1 extra square4 triangles

This new configuration is balanced. I added the 2 triangles to the left side while the right side got the square.

There are other configurations possible because we can add as many squares to each side, as long as we add 2 triangles per extra square. Also, the order of the shapes on either side doesn't matter. All that matters is the total weight pulling down.

Also, we could easily add the same shape to both sides as possibly the easiest way to change the configuration. For instance, if you add a circle to both sides, then things stay balanced. So again, there are many ways to answer this.

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 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.
