Michelle has a bag with marbles in it. Some of the marbles are blue, some are green, and some are yellow. She draws one marble a

t random, records the color, and returns it to the bag.
Here is her data after 500 trials:
blue: 120
green:119
yellow:261

She wants to know the probability of drawing a blue marble from the bag. Which of these probabilities is most likely?

3 0

Answer:

24% (0.24)

Step-by-step explanation:

Using the data from her 500 trials, we can predict the probability of her drawing a blue marble from the bag by dividing the number of times she drew a blue marble (120) by the total of trials she performed (500).

120 ÷ 500 = 0.24

0.24 = 24%

~Hope this helps!~

3. A cone has a heighth and a base with radius r. You want to change the cone so its volume is tripled. What is the new height i
Sphinxa [80]

Answer:

Hence the new height  is 3 times the original height .(h1=3h)

Step-by-step explanation:

Given:

A cone with  has height and base with radius r .

To Find:

What is new height

Solution:

Consider as cone with height h base radius r, and volume v

Here given that only height changes for the cone  i.e. r remains the unchanged or same or constant

The volume for a regular cone is given by ,

V=pie*r^2*h/3

Here V is directly proportional to h i.ee pie ,3 and r being constant

V=K*h

i.e V/h=constant

V1 and h1 are new dimensions for new cone

V/h=V1/h1

Here V1=3V

So V/h=3V/h1

1/h=3/h1

i.e  h1=3h

Hence the height  is 3 times the original height .

Kalsom answers 25 questions in math tests. He scored 81% to 93%. Calculate all possible number of questions successfully answere
cricket20 [7]

Answer:

21 and 22

Step-by-step explanation:

Let's work backward from that 81%:  x/25 = 0.81 yields x = 20.25.  Nominally, 20.25 / 25 = 0.81, but x must be an integer.  Let's round 20.25 off to 20.

Thus, if Kalsom got 81%, it was a result of his having done 20 questions correctly.

81% corresponds to 20 questions correct;

82% to 20.5 questions correct, or, rounding up, to 21 questions correct;

83% to 20.75, or 21;

84% to 21 questions correct; this is the only result that makes sense (whole number of questions answered correctly)

85% to 21.25;

86% to 21.5;

87% to 21.75;

88% to 22 questions correct (this makes sense, unlike the last three)

89% to 22.25;

90% to 22.5;

91% to 22.75;

Assuming that the number of questions correct MUST be integer, then the possible number correct are 21 and 22, corresponding to 84% and 88% respectively.

The baseball coach is 70 inches tall. How tall is the child?
tankabanditka [31]

The child is <u>59.4 inches tall</u>, assuming the length from the coach's shoulder to his head cap is approximately 10 inches.

<h3>What is Heigth?</h3>

Height refers to the vertical distance between the top and bottom of something.

Height measures the length of some objects or persons vertically to determine whether it is high or low, according to some ascertained criteria.

<h3>Data and Calculations:</h3>

Baseball coach's height = 70 inches

Coach's shoulder to head = 10.6 inches

Height of the child standing slightly below the coach's shoulder = 59.4 inches (70 - 10.6)

Thus, the child standing slightly below the coach's shoulder is 59.4 inches tall.
