Answer:
The point is [tex]\mu - 98[/tex], in which [tex]\mu[/tex] is the average per month.
Step-by-step explanation:
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.
Normal distribution with an average of per month and a standard deviation of $50 per month.
Average of [tex]\mu[/tex], standard deviation [tex]\sigma = 50[/tex]
Find the point in the distribution below which 2.5% of the PCE's fell.
This is below the 2.5th percentile, which is the X when Z has a pvalue of 0.025, so X when Z = -1.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.96 = \frac{X - \mu}{50}[/tex]
[tex]X - \mu = -1.96*50[/tex]
[tex]X = \mu - 98[/tex]
The point is [tex]\mu - 98[/tex], in which [tex]\mu[/tex] is the average per month.

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:
[tex] \displaystyle x = \log_{3}(78) [/tex]
by using calculator
[tex] \displaystyle x = 3.97[/tex]

A probability model includes p(red)=2/7 and P(blue)=3/14. Select all the probabilities that could complete the model.
Answer Key:
A: P(green)= 2/7, P(yellow)=2/7
B: P(green)=3/8, P(yellow)=1/8
C: P(green)=1/4 P(yellow)=1/4
D: P(green)= 5/21 Pyellow)= 11/21 E. P(green)= 3/7 P(yellow)=1/14
Answer:
The answer is "Option D".
Step-by-step explanation:
In this question, the shape of the model is not declared that why we assume that it has four sides in which two sides are given that is:
[tex]\to P(red)=\frac{2}{7} \\\\\to P(blue)=\frac{3}{14}[/tex]
other probabilities are:
[tex]\to P(green)= \frac{5}{21} \\\\\to P(yellow)= \frac{11}{21}[/tex]

after simplifying, what will x be equivalent to? (a^4)^6=a^x
Answer:
x will be equivalent to 24
Step-by-step explanation:
apply the multiplication rule to the exponents in (a^4)^6
4 times 6= 24, so (a^4)^6 is equivalent to a^24
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

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

Answer:
66 cm²
Step-by-step explanation:
The area of the polygon is the sum of the areas of the triangle and the rectangle it sits on. The dimensions of the triangle can be found by examining the top/bottom dimensions shown and the left/right dimensions shown.
The width (base) of the triangle is the difference between the lengths of the bottom and top horizontal lines: (12 -9) cm = 3 cm.
The height of the triangle is the difference between the lengths of the left and right sides of the figure: (9 -5) cm = 4 cm.
The dimensions of the rectangle are shown a the bottom and the left sides of the figure.
triangle area = 1/2bh = 1/2(3 cm)(4 cm) = 6 cm²
rectangle area = LW = (12 cm)(5 cm) = 60 cm²
Total polygon area = 6 cm² + 60 cm² = 66 cm²
