Gerald buys a bag of 7,500 assorted beads online. A random sample of 150 beads contains 17 red beads. Predict the number of assorted beads that Gerald bought.

500 red beads

7,350 red beads

850 red beads

167 red beads

Answers

Answer 1

Answer:

C : 850 Red Beads

Step-by-step explanation:

you do 7500/150 which is 50.

you times 17 by 50 since you know in every 150 beads 17 are reds so you get 850 red beads and you times 150 by 50 and get 7500 so in 7500 you get 850 red beads.

Think of the decimals in the probability column as percentage. So Micheal has a 30% chance of eating the next fry, Lidia would have a 10% chance, so on and so forth.

The percentage will always go up to 100%.

You're given the other people's percentages, but not Ronald.

Domarina is making bracelets. she needs 62 cm of gold wire for each bracelet. A roll of wire has 3.10 meters. How many bracelets can she make from one roll of wire.

Answers

Answer:

5

Step-by-step explanation:

To figure this out you first need to find how many centimeters 3.10 meters is worth. 3.10m=310cm. Then, since each bracelet needs 62 cm, you just do 310/62. 310/62=5 So you can make 5 bracelets with one roll of wire.

Answer:

the answer is B : 7

Step-by-step explanation:

Answer:

B. 7

Step-by-step explanation:

According to the word problem, Muna is dividing a piece of string that 42 2/3 long into 2/3 pieces.

[tex]\frac{14}{3} /\frac{2}{3}[/tex] (changed to an improper fraction)

Whenever dividing fractions, remember this:

SAME, CHANGE, RECIPROCAL (FLIP)

KEEP THE FIRST FRACTION THE SAME

CHANGE THE DIVISION SIGN TO A MULTIPLICATION SIGN

FLIP THE SECOND FRACTION

[tex]\frac{14}{3} *\frac{3}{2} =\frac{42}{6}[/tex]

[tex]\frac{42}{6} =7[/tex]

I, therefore, believe Muna will have 7 pieces of string.

Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.

His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.

In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.

Assuming there are no outliers or skew, do the results support Garret's theory?

Select from the drop-down menus to correctly complete the statements.

Since the samples were large and randomly chosen, we can use the samples to understand the populations.

Angel decides to exceed the walking challenge goal. Describe two ways you might adjust the equation or inequality in Part A to represent Angel’s decision to exceed the goal. Give an example and explain.

Answers

Answer:

Step-by-step explanation:

The original distance that Angel wanted to walk will be represented as A

Since we don't know the additional distance Angel walked it'll be represented as B

A= the amount of distance Angel wanted to walk

B= the amount of distance Angel wanted to walk past his/her challenge goal

C= the amount of distance Angel walked originally from to past her/his challenge goal

A+B=C

Example:

I decide to work for A hours today as a challenge. Within this time I'm working I decided to extend my goal another B hours.
