Answer:
(5,-3)
Step-by-step explanation:
Given that,
The coordinates of Q = (3,1)
The midpoint of QR = (4,-1)
We need to find the coordinates of point R.
We know that, according to mid-point theorem,
[tex](x_m,y_m)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
Let (x₂,y₂) be the coordinates of point R.
So,
[tex](4,-1)=(\dfrac{3+x_2}{2},\dfrac{1+y_2}{2})\\\\\dfrac{3+x_2}{2}=4\ and\ \dfrac{1+y_2}{2}=-1\\\\3+x_2=8\ and\ y_2+1=-2\\\\x_2=5\ and\ y_2=-3[/tex]
So, the coordinates of point R is (5,-3).

Answer:
[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:

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

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

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)

How many yards of fence does Raul need to
fence in a garden that is 12ą yards long and 9
yards wide?
Don’t tell me to “download the answer” that’s bs
Answer:
Raul needs 42 yards of fence.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w)
In this question:
The fence is rectangular.
12 yards long means that l = 12.
9 yards wide means that w = 9.
Perimeter:
P = 2(12 + 9) = 2(21) = 42
Raul needs 42 yards of fence.

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.
