Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red. The other half were black. Josh predicted that he would choose a red card in 4 out of 8 trials. When he conducted the experiment, he actually chose a red card 6 out of 8 times. Which explains the most likely reason for the discrepancy between Josh’s predicted and actual results?He incorrectly predicted the number of times he would choose a red card.
He incorrectly determined the actual number of times he chose a red card.
He used too few trials for the sample space.
He used too many trials for the sample space.

Answers

Answer 1

Answer:

Step-by-step explanation:

He used too few trials for the sample space.

If he conducts a lot more trials, his results will be closer to 50% red

What are the coordinates of point A?
A. (0,-4)
B. (-4,0)
C. (4,0)
D. (0,4)

Answers

Answer:

(0,-4)

Step-by-step explanation:

The x coordinate comes first in the ordered pair

We do not move left or right from the origin so the x coordinate is zero

The y coordinate is second, we move 4 units down so the y coordinate is negative 4

The ordered pair is (0,-4)

0,-4 coordinates of point A

A 10 miles per hour
b 15 miles per hour
c 30 miles per hour
d 65 miles per hour

Answers

Answer: B) 15 mph

====================================================

Explanation:

The equation d = 65t means that the rate is r = 65. So Malcolm's family travels at an average rate of 65 mph. Note this is the slope of the line.

The graph has a slope of 50 because each time we go up 50, we move to the right 1. Ie, slope = rise/run = 50/1 = 50. You could use the slope formula to get the same result.

Since the graph has a slope of 50, this means Theo's family is going at an average speed of 50 mph.

Subtract the two speeds to get 65-50 = 15 mph

Given f(x) = x – 10, what is f(–7)?A.
–17

B.
–10

C.
–7

D.
–3

Answers

Answer: A. $-17$

Step-by-step explanation:

Here, the given function is,

$f(x) = - x - 10$

By substituting x = -7

We get,

$f(-7) = -7 - 10$

$\implies f(-7) = - (7+10)$

$\implies f(-7) = -17$

Thus, the value of $f(-7)$ is $17$ .

⇒ Option A is correct.

easy
put -7 for every x
f(x)=x-10
f(-7)=-7-10
f(-7)=-17
