Answer:
y=0.5x-1
Step-by-step explanation:
First you need to find the gradient of the line. Since x goes up by 0.5 every time y goes up by 1, the gradient is 0.5. Then you need to find the y intercept which is what x equals when y is equal to 0. When y equals zero x equals negative 1. If ylu use the equation y=mx+c where m=gradient and c=y intercept you get y=0.5x-1
Answer:
The answer is A 41.9 feet.
Answer:
Step-by-step explanation:
Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test reults
µ = mean score
σ = standard deviation
From the information given,
µ = 1700 points
σ = 75 points
We want to the probability that a student will score more than 1700 points. This is expressed as
P(x > 1700) = 1 - P(x ≤ 1700)
For x = 1700,
z = (1700 - 1700)/75 = 0/75 = 0
Looking at the normal distribution table, the probability corresponding to the z score is 0.5
P(x > 1700) = 1 - 0.5 = 0.5
Answer:10
Step-by-step explanation:
Divide 12.75 by 1.25
you get 10.2
She can cut 10 strings but has 0.2 string leftover
Answer:
4 3/8 yards.
Step-by-step explanation:
2 5/8 = (2*8 + 5)/8 = 21/8.
1 3/4 = (1*4 + 3) / 4 = 7/4.
21/ 8 + 7/4
= 21/8 + (7*2) / (4*2)
= 21/8 + 14/8
= 35/8
= 4 3/8.
