Draw a pick of 19 ÷4

Mars2501 [29]

Ill break it down for you so you can understand.

We use a method called "long division" to help us divide large numbers. But, if it does not go in, we need to make it into a decimal. Observe.

4 ⟌19

Four does not go into one. (Start with the first number then go right if it doesn't go in.) ((Also add a 0 up top)

4 ⟌19

4 does not go into 19 but it can go into 16. (Put a four at the top.)

4 ⟌19

-16

____

Now, if it can't go in, then put a point after the 4 and add a zero to the three.

04.75

4 ⟌19

-16

____ (4 x 7)

30 28

-28

____

2 (0) (5 x 4)

20 20

_____

Your answer is 04.75 OR 4.75.

Hope this helps. Also have a lovely day! ~Pooch ♥

A jar contains balls numbered 1 to 10. Two balls are drawn with replacement. What is the probability that both balls are numbere

Elenna [48]

Answer:

Step-by-step explanation:

The number of ways that you can draw 2 balls without restriction is 10 * 10 = 100

Two balls will give you 2 or less (meaning 1) or 2*2 = 4

Four ways are possible

2 and 2

2 and 1

1 and 2

1 and 1

4/100 = 1/25 is the probability of making this happen.

A student's grades in the three tests in College Algebra are 85, 60, and 69. a) How many points does the student need on the fin

Anastaziya [24]

Answer:

(a) The student need 82 points on the final to average 74.

(b) The student must score 41 points on the final, assuming that the final carries double the weight.

Step-by-step explanation:

We are given that a student's grades in the three tests in College Algebra are 85, 60, and 69.

As we know that the formula for calculating the average of numbers is given by;

Average (Mean) = $\frac{\text{Sum of all values}}{\text{Number of observations}}$

(a) Let the points student need on the final test to average 74 be ' $x$ '.

So, Average of all four test = $\frac{85+60+69+x}{4}$

$74 = \frac{85+60+69+x}{4}$

$74 = \frac{214+x}{4}$

$214+x =74 \times 4$

$x = 296-214$

$x=82$

Hence, the student needs 82 points on the final to average 74.

(b) It is given that the final carries double the weight, this means that let the points student need on the final test to average 74 be ' $2x$ '.

So, Average of all four test = $\frac{85+60+69+2x}{4}$

$74 = \frac{85+60+69+2x}{4}$

$74 = \frac{214+2x}{4}$

$214+2x =74 \times 4$

$2x = 296-214$

$x=\frac{82}{2}$ = 41

Hence, the student must score on the final 41 points, assuming that the final carries double the weight.
