Solve 3b−42=c, for b.
Answer:
b=1/3c+14
Step-by-step explanation:
Let's solve for b.
3b−42=c
Step 1: Add 42 to both sides.
3b−42+42=c+42
3b=c+42
Step 2: Divide both sides by 3.
3b
3
=
c+42

Answer:
b= 1 /3 c+14
Step-by-step explanation:
Add 42 to both sides.
3b−42+42=c+42
3b=c+42
Divide both sides by 3.
3b/3=c+42/3
b=1/3c+14

Answer:
BCD = 90˚
ABD = 16˚
CBE = 74˚
ADE = 74˚
AEB = 148˚
DEA = 32˚
Step-by-step explanation:
BCD: I suppose that’s a rectangle, and all rectangles have four right (90˚) angles.
ABD: alternate interior angles are congruent, so ABD is congruent to BDC (16˚).
CBE: Complementary angles add up to 90˚, so just subtract ABD (16˚) from 90˚ to equal 74˚.
ADE: Same this as CBE for same reason.
AEB: You need to find DEC first for this. To find DEC, add BDC and ACD together to get 32˚, then subtract that from 180˚ to find the answer (148˚). This is because all triangles have a 3 interior angle measure sum of 180˚. (And vertical angles are congruent).
DEA: Subtract AEB from 180˚ because they’re supplementary angles.

A study was designed to investigate the effects of two variables (1) a student's level of mathematical anxiety and (2) teaching method on a student's achievement in a mathematics course. Students who had a low level of mathematical anxiety were taught using the traditional expository method. These students obtained a mean score of with a standard deviation of on a standardized test. Assuming a mound-shaped and symmetric distribution, in what range would approximately % of the students score?
Answer:
Solution using the Empirical Rule, which is explained here.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
The question is incomplete, but you solve this using the Empirical Rule.

The time between arrivals of customers at an automatic teller machine is an exponential random variable with a mean of 4 minutes. Round yours answers to 4 decimal places. (a) What is the probability that more than three customers arrive in 10 minutes
Answer:
0.7788 = 77.88% probability that more than three customers arrive in 10 minutes
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability that x is lower or equal to a is given by:
[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]
Which has the following solution:
[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
In this question, we have that:
The time between arrivals of customers at an automatic teller machine is an exponential random variable with a mean of 4 minutes, and we have three customers, which means that [tex]m = 3*4 = 12, \mu = \frac{1}{12} = 0.0833[/tex]
(a) What is the probability that more than three customers arrive in 10 minutes
This is P(X > 3). So
[tex]P(X > 3) = e^{-0.0833*3} = 0.7788[/tex]
0.7788 = 77.88% probability that more than three customers arrive in 10 minutes

the equation of the line please
Answer:
x = 4
Step-by-step explanation:
The line is a vertical line. The equation of a vertical line is represented as x = k.
Where, k is the point at where the line intercepts the x-axis.
In the graph given, the line intercepts the x-axis at 4. k = 4.
Therefore the equation of the vertical line would be:
x = 4
The rectangular base of a 3-D printer East 4.5' by 3' in the Keogh's drawing the base of the printer is 3" by 2" of nicaea in larger drawing to 3 times its size would foot the scale of her events draw
Answer:
[tex]Scale = 1.5[/tex]
Step-by-step explanation:
Given
[tex]Printer = (4.5',3')[/tex]
[tex]Keogh = (3',2')[/tex]
Required
Determine the scale
This is calculated as:
[tex]Scale = \frac{Original}{Actual}[/tex]
[tex]Scale = \frac{(4.5,3)}{(3,2)}[/tex]
Factorize the numerator
[tex]Scale = \frac{1.5 * (3,2)}{(3,2)}[/tex]
Scale = \frac{1.5 * (3,2)}{(3,2)}[tex]Scale = 1.5 * \frac{(3,2)}{(3,2)}[/tex]
[tex]Scale = 1.5 * 1[/tex]
[tex]Scale = 1.5[/tex]

Write the expression 17 4/3 using radicals :)
The expression can be expressed as radicals in terms of [tex]\mathbf{\sqrt[3]{17^4} }[/tex]
A radical expression is an expression that can be written in square root form. It is an opposite form of an exponent and its power determines the root in which it is been evaluated.
Here, we are given:
[tex]\mathbf{\implies 17^{^\dfrac{4}{3}}}[/tex]
The denominator in the power will be the root of the expression given, since it is 3 it will be the cube root raised to the power of 4.

1.0 is what percent of 3.5
Answer:
28.57%
Step-by-step explanation:
Let the required percent be x
1.0 is what percent of 3.5 is written as;
1.0 = x% of 3.5
1.0 = 0.01x * 3.5
0.01x = 1/3.5
0.01x = 0.2857
x = 0.2857/0.01
x = 28.57%
Hence 1.0 is 28.57% of 3.5

(3) Median
Step-by-step explanation:
I would say median because it most likely wouldn't be any of the others. Mean would be thrown off with the outlier 0.80. Mode wouldn't really work for this. I don't think standard deviation would work because this isn't coninuous data.
