Answer:
The area (probability) is: 0.6864.
Step-by-step explanation:
According to the statement, we are in front of a normal distribution with the following parameters:
µ (mean) = 0
σ (Standard deviation) = 1.
Then we need to find the area of the shaded region, which is the area between the points -1.21 < z < 0.84.
And the area (probability) is: 0.6864.
Answer:
Slope = ⅓ Y-intercept = -2
Step-by-step explanation:
by transforming the equation to y= ⅓x -2
then it becomes Y= ⅓x +(-2)
then you should get m= ⅓ and b = -2
Answer: 15:13
Step-by-step explanation: 7/7=3500
<h2>
1/7=3500÷7=500</h2><h2>
500x3=1500</h2><h2>
1500+700=2200</h2><h2>3500-2200=1300</h2><h2>1500:1300</h2><h2>15 : 13 (if there is a need to simplify the ratio)</h2><h2 />
Answer:
2 miles = 3,520 yards
first we need to find how many yards she's walked already :
400×5=2,000 yards
now subtract :
3,520-2,000= 1,520 yards
Keisha needs to walk 1,520 more yards to complete 2 miles
hope this helped
