A set of cards contains cards numbered 1 – 8. Mrs. Jacob’s class is conducting an experiment in which a card is drawn from the pile, the number is recorded, and then the card is returned to the set. The class will conduct 1,000 trials. Based on the theoretical probability, which is the best prediction for the number of times a 4 will be drawn from the pile?

Answers

Answer 1

Answer: 125

The best prediction for the number of times a 4 will be drawn from the pile is:

A set of cards contains cards numbered 1 – 8.

So, the theoretical probability that 4 comes up is:

Ratio of Number of favorable outcome( outcome of 4) to the total umber outcome(i.e. 8 )

Hence, Theoretical Probability that 4 is drawn=1/8

Now, out of 1000 trials the best prediction of number of times 4 is drawn is:

(The probability of drawing 4)×(Number of experiments or trials)

=(1/8)×1000

=125

What is the intercept of

Answers

Answer:  The y-intercept of y = -1/2x -1  is (0,-1)

The y-intercept of y = 1/4x -4  is (0,-4)

The attachment shows the graph of these equations.

Step-by-step explanation:

Both equations are in slope-intercept form. y = mx + b

The constant, b, is the y-intercept.

The y-intercept of y = 1/2x -1  is (0,-1)

The y-intercept of y = 1/4x -4  is (0,-4)

What is y- intercept?

On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

Given:

y=-1/2x-1 and y=1/4x-4

For Finding the y- intercept put x= 0 we get

y = -1/2(0) -1

y= 0- 1

y= -1.

For Finding the y- intercept put x= 0 we get

y=1/4(0)-4

y= 0- 4

y= -4

segment AE and segment BD bisect each other

Which means :

∠BCA and ∠DCE are equal because they are vertically opposite angles. Segment AC = segment CE because the bisector BD divides the segment AE into two equal parts which are segment AC and segment CE.segment BC and segment CD will be equal because bisector AE divides the segment BD into two equal parts which are segment BC and segment CD.

The sum of an equation is 45/100

One addend is 4/10
What is the missing addend?

Answers

Answer:

The missing addend is 1/20

Step-by-step explanation:

Variable x: missing addend

4/10 + x = 45/100

When adding or subtracting fractions, the denominators must be the same number.

To convert 10 to 100, we must multiply 10 by 10.

If we multiply 10 to the denominator, we must do the same to the numerator (multiply by 10).

4 × 10 / 10 × 10

40/100

Use this fraction in the equation now

40/100 + x = 45/100

Now isolate the variable, x, by subtracting 40/100 from both sides

40/100 - 40/100 + x = 45/100 - 40/100

When subtracting fractions, only subtract the numerators. The denominators remain the same

x = 5/100

Simplify 5/100

Both numbers can be divided by 5

5 ÷ 5 / 100 ÷ 5

1/20
