The x intercept is the x value when y is 0.
So,
0 = 2/5x + 5
-5 = 2/5x
-25 = 2x
The x intercept is -25/2.
<h3><u>It's called a difference.</u></h3>
When you're subtracting one quantity from another, the answer is known as the difference.
There's a different name depending on the symbol.
In addition, it's the sum.
In multiplication, it's the product.
In division, it's the quotient.
Answer:
Step-by-step explanation:
standard deviation σ =5000
Mean μ = 36500
X = 30000
Probability that tire fails to reach 30000 miles
P(< 30000) = P( z < (30000-36500) / 5000 )
= P ( z < - 1.3 )
= .0968 ( from z table )
refund per mile = .01
refund for 30000 mile = .01 x 30000 = 300
expected cost of promotion
= 300 x .0968
= 29.04
b )
refund of $50 is equivalent to shortage of milage by 50 / .01 = 5000 miles
Probability of miles less than 30000 - 5000 = 25000
P ( X < 25000 ) = P ( z < (25000 - 36500) / 5000 )
P ( z < - 2.3 )
= 0.0107 Answer .
To solve for d, it is important to remember that we can only add or subtract like terms. Also, that we have to isolate the variable should be solved to one side and all others to the other side. We do as follows:
<span>−2/3x 3/8x = −7/12−1/4x
</span><span>−2/3x 3/8x = −7/12−1/4x
1/4x = </span> −7/12−1/4x
1/2x = -7/12
x = -7/6
