Markene would be able to buy the dress because 180-20% is 148 and 148<150 meaning that her mom would pay the taxes
First what you need to do is 4.2 x 0.6 and that will be you answer.
A = 1
b = -5
c = -4
x1 = 5.70
x2 = -0.70
<span>Therefore, the negative real number is -0.70.</span>
Answer:
y^(-5/4)
Step-by-step explanation:
because
1/ (y^(5/4) = (1/y) ^(5/4) = y^(-5/4)
The correct option is (B).24 miles.
Z-score is basically another term for the specific number of standard deviations. I suppose we can assume normality here, even though it isn't given, so I'd make a rough sketch.
Otherwise, just use the basic formula:
Given that,
(statistic for a mean) and
(statistic for a standard deviation).
Since z-score must be Less than 1.5, So
![1.5> \dfrac{x-29}{3.6}\\](https://tex.z-dn.net/?f=1.5%3E%20%5Cdfrac%7Bx-29%7D%7B3.6%7D%5C%5C)
![1.5 \times3.6 > x-29\\5.4+29> x\\34.4> x](https://tex.z-dn.net/?f=1.5%20%5Ctimes3.6%20%3E%20x-29%5C%5C5.4%2B29%3E%20x%5C%5C34.4%3E%20x)
I just used normal cdf and got
.
Hence the correct option is (B).24 miles.
