Answer:
y = 3x + 5
Step-by-step explanation:
The equation in slope- intercept form is
y = mx + c
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (2, 11) ← 2 ordered pairs from the table
m =
=
= 3, thus
y = 3x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (2, 11 ), then
11 = 6 + c ⇒ c = 11 - 6 = 5
y = 3x + 5 ← equation of linear function
Answer:
Meridith doesn't get hit 65% of the time.
Step-by-step explanation:
If you take the 35% that she does get hit and subtract that from 100% then you will get 65%. (100-35=65)
Answer:
gives the solution
.
gives the solution
.
Step-by-step explanation:
I will solve both interpretations.
If we assume the equation is
, then the following is the process:

Add 5 on both sides:

Simplify:

Now write an equivalent logarithm form:


Now using the change of base:
.
If we assume the equation is
, then we use the following process:

Write an equivalent logarithm form:


Add 5 on both sides:

Use change of base formula:

Answer:
4.75% probability that the line pressure will exceed 1000 kPa during any measurement
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What is the probability that the line pressure will exceed 1000 kPa during any measurement
This is 1 subtracted by the pvalue of Z when X = 1000. So



has a pvalue of 0.9525
1 - 0.9525 = 0.0475
4.75% probability that the line pressure will exceed 1000 kPa during any measurement
