Answer:

y + 13 = 4(x - 7)

Step-by-step explanation:

Point-slope: y - y1 = m(x - x1)

Using (7,-13) and m = 4

y - -13 = 4(x - 7)

y + 13 = 4(x - 7)

OLEGan [10]

Answer: 1 : 1.48

Step-by-step explanation:

400 : 592

1       : x

Cross multiply:

400x = 592

x = 592/400

x = 1.48

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 p
Alchen [17]

Answer:

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

                       125

Step-by-step explanation:

It is given that:

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
