Answer:
84.13% probability a particular tire of this brand will last longer than 57,100 miles
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:
What is the probability a particular tire of this brand will last longer than 57,100 miles
This is 1 subtracted by the pvalue of Z when X = 57100. So
has a pvalue of 0.1587
1 - 0.1587 = 0.8413
84.13% probability a particular tire of this brand will last longer than 57,100 miles
Answer:
5.7 liters
Step-by-step explanation:
The sum of 2 liters, 5 deciliters of lemon juice and 3 liters, 2 deciliters of water will be given as
2+3=5 liters
5+2=7 deciliters
Therefore, we get 5 liters, 7 deciliters of lemonade
Conversion
10 deciliters equal to 1 liter hence 7 deciliter will be 7/10=0.7 liters
5+0.7=5.7 liters
Slope intercept form is y=mx+b
to solve for m (slope) you must first subtract y2-y1 and x2-x1 then divide your answers
-1 - -5 = 4 (y)
2 - 4 = -2 (x)
4/-2 = -2
so your slope is -2
next plug in your slope and the point you choose
-1 = -2(2) + b
or
-5 = -2(5) +b
The product of multiplication of 16 × 9 gives us; 144
<h3>Multiplication</h3>
We want to find the product of 16 and 9.
Now, to solve this we can use a little illustration for example if I have a basket of oranges and I want to given 9 people each 16 oranges, it means that the total number of oranges I will give out is; 16 × 9 = 144
Thus, our question answer is 16 × 9 = 144

<u>Answer</u>:
Option 5: -4 ≤ 7x - 7 ≤ 4
<u>Step-by-step explanation:</u>
It is required to find which expression is equivalent to |7x-7| ≤ 4
So, at the beginning we should review the rules of absolute value inequalities.
1) If |x| ≤ a ⇒ -a ≤ x ≤ a
2) If |x| < a ⇒ -a < x < a
3) If |x| ≥ a ⇒ x ≤ -a or x ≥ a
4) If |x| > a ⇒ x < -a or x > a
Applying the first rule to the given absolute value inequality:
|7x-7| ≤ 4 ⇒ -4 ≤ 7x-7 ≤ 4
So, the answer is option 5
