Answer:

y=x+3

Step-by-step explanation:

1.) Find slope

slope = (-1-3)/(-4-0)

= -4/-4

= 1

2.) Use point slope form

y-y1= m (x-x1)

both x1 and y1 are the points

m is the slope

3.) Plug in the numbers

for the points I chose (0,3) to plug in

y-3= 1 (x1-0)

y-3= x

y= x+3

Yolanda watches a carnival game in which a paper cup is tossed. It costs $1 to play the game. If the cup lands upright, the play

trapecia [35]

Answer:

Step-by-step explanation:

a. Yolanda only wins if the cup lands upright.

From the experimental data we see that the probability of winning is 5 out of 50, or

10%. Therefore, if Yolanda plays 10 times she can expect to win 10% of 10 times = 1

time. She will lose 9 times. (Note: Ten trials is a very small number of trials, so we should not be surprised if Yolanda’s results are very different from the percentages

produced by the longer experiment.)

b. If Yolanda wins 1 time and plays 10 times, she will have spent $10 to play and won

back only $5, so she would have less money at the end of 10 games.

Fatima earned an 85 average in her science class. The average is based on 6 tests that she takes over the span of the marking pe

LenaWriter [7]

Answer:

Fifth Score = 87

Sixth Score = 95

Step-by-step explanation:

Given

$Average = 85$

$Scores = 83, 78, 87, 80$

$Fifth\ score = x$

$Sixth\ Score = 8 + x$

Required

Set up an equation

Solve for the fifth and sixth score

Average is calculated as thus:

$Average = \frac{\sum x}{n}$

$Average = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}$

Substitute 85 for Average

$85 = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}$

$85 = \frac{83 +78 + 87 + 80 + 8+ x + x}{6}$

$85 = \frac{336+ 2x}{6}$

Multiply both sides by 6

$85 * 6 = 336 + 2x$

$510= 336 + 2x$

Solve for 2x

$2x = 510 - 336$

$2x = 174$

Solve for x

$x = 174/2$

$x = 87$

Hence:

$Fifth\ Score = 87$

$Sixth\ Score = 87 + 8$

$Sixth\ Score = 95$
