x?+6x^2+12x-136
I think this is the answer
Answer:
6x2−11x−136
Step-by-step explanation:
Let's simplify step-by-step.
6x2−12x+48−(−x+247−63)
Distribute the Negative Sign:
=6x2−12x+48+−1(−x+247−63)
=6x2+−12x+48+−1(−x)+(−1)(247)+(−1)(−63)
=6x2+−12x+48+x+−247+63
Combine Like Terms:
=6x2+−12x+48+x+−247+63
=(6x2)+(−12x+x)+(48+−247+63)
=6x2+−11x+−136

Step-by-step explanation:
Given that v = (5,-4,4) and w = (9,-2,7) evaluate v • w.
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

The value of q is 36 in the equation q+9=45
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is q+9=45
q plus nine equal to forty five
We have to find the value of q
Plus is the operator
q is the variable
Subtract 9 from both sides
q=45-9
q=36

Add one set of parentheses to the expression 2x² + 4 - 5 so that the value of the expression is 75 when x = 6
Answer:
answer is +4...
Step-by-step explanation:
when x=6, the expression becomes
2(6)^2+ 4-5
2(36)+(-1)
72-1=71
therefore 71+4 gives 75
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 is the approximate area, in square units, of the circle shown below?
