Katja would be the straight line and joels line would show sections that stop going up it would intersect at some point because katja is constantly moving while joel takes breaks in-between

Answer:

Jerry would be the purple line on the graph.

We can see that he goes faster than Katja as the gradient is greater than katja's until he stops for a period of time and that's why we see that as time passes, the distance doesn't go up until he starts running at a faster pace than Katja.

Katja is the orange line on the graph, where she is moving at a slower constant pace and that's why the gradient of the line is less steep. However, she never stops as the distance always goes up as the time increases.

The intersection point is the moment and distance where Katja surpasses Jerry.

Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items wit
weeeeeb [17]

Answer:

Change = \$8.82

Step-by-step explanation:

Given

Basketball = \$25.57

Air\ Pump = \$15.61

Amount = \$50

Required

Determine the change received

First, we need to calculate the total amount spent

Total = \$25.57 + \$15.61

Total = \$41.18

This implies that Natalie pays a total of $41.18

Next, we calculate the change as thus:

Change = Amount - Total

Change = \$50 - \$41.18

Change = \$8.82

<em>Hence, the change is $8.82</em>

From past results, a professor knows that the test score of a student taking her final examination is a random variable with mea
umka2103 [35]

Answer:

option B

Step-by-step explanation:

Given,

mean result (μ) = 65

standard deviation (σ)= 15

probability that student will score between 50 and 80

= P(50< x

= P(50< x

= P(50< x

 = P(Z < 1) - P(Z < -1)

Using z table,  

= 0.8413 - 0.1587

= 0.6826

the correct answer is option B

Step-by-step explanation:

3x - 4y = 15

-2x + 3y = 10

Add the two equations together

 3x - 4y = 15

-2x + 3y = 10

----------------------

x - y = 25
