Answer:
$9.35
Step-by-step explanation:
Find the sale price by multiplying 13.35 by 0.7, since this will be 70% of the original price
13.35(0.7)
= 9.345
This rounds to approximately 9.35
So, you will pay $9.35
Answer:
9.35 would be the answer!

23. The mean weight of trucks traveling on a particular section of 1-475 is not known. A state highway inspector needs an estimate of the mean. He selects a random sample of 49 trucks passing the weighing station and finds the mean is 15.8 tons, with a standard deviation of the sample of 4.2 tons. What is probability that a truck will weigh less than 14.3 tons
Answer:
0.3594 = 35.94% probability that a truck will weigh less than 14.3 tons
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
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 p-value, we get the probability that the value of the measure is greater than X.
Mean is 15.8 tons, with a standard deviation of the sample of 4.2 tons.
This means that [tex]\mu = 15.8, \sigma = 4.2[/tex]
What is probability that a truck will weigh less than 14.3 tons?
This is the pvalue of Z when X = 14.3. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{14.3 - 15.8}{4.2}[/tex]
[tex]Z = -0.36[/tex]
[tex]Z = -0.36[/tex] has a pvalue of 0.3594
0.3594 = 35.94% probability that a truck will weigh less than 14.3 tons

What would be the volume of this solid if the height were halved and the other dimensions were reduced proportionally? Round to the nearest whole number.
A. 13 cm3
B. 26 cm3
C. 15 cm3
D. 21 cm3
no dam links
Answer:
The height for the original part is 10 cm
Never mind that the solid is standing at the angle of 60 degrees.
If you cut the bottom of the solid at the angle of 30 degrees, and put that part on the top of the solid,
the height is going to be exactly 10 cm.
So, we have... V = (10 * 4 * 3) / 8
or V = 5 * 2 * 1.5

What are some advantages of different ways to solve an equation?
Answer:
When you have different forms of equations you can then see equivalencies. the different forms of equations can then be solved, each in its own manner. meaning sometimes you can not solve one way because the equation is nested within another, a function in a function. F(x)=f(g(x)) Then you can work the problem around to different forms until you get your solution

A. 81
B. 19
C. (45,8,28)
D. (-40,-16,-8)
Answer:
81
Step-by-step explanation:
Evaluating v • w
Recall: Given vectors a and B in Cartesian plane, x, y and z
vector a = [ax ay az] and b = [bx by bz]
The dot product is :
a•b = axbx + ayby + azbz
Using the relation above,
v • w = (5*9) + (-4*-2) + (4*7)
v • w = 45 + 8 + 28
v • w = 81
Hence, v • w = 81

[tex] \displaystyle x = 3.97[/tex]
Step-by-step explanation:
we are given a exponential equation
[tex] \displaystyle {3}^{x} = 78[/tex]
we want to figure out x
remember that,
[tex] \displaystyle \log_{a}( {a}^{c} ) = c[/tex]
thus
take [tex]\log_3[/tex] both sides:
[tex] \displaystyle \log_{3}( {3}^{x} ) = \log_{3}(78) [/tex]
use the formula:
