When a molding is randomly selected from the early morning run of a random day, what is the probability that it is defective is 0.1051
How to calculate the probability?A probability is a numerical representation of the likelihood or chance that a specific event will take place. Probabilities can be written as percentages with values between 0 and 1.
From the information, the foreman for an injection-molding firm admits that on 29% of his shifts, he forgets to shut off the injection machine on his line.
The probability that the selected molding is defective will be:
= P(forgets to shut off and defective molding) + P(not fingers to shut off)
= 29% × 24% + (1 - 29%) × 5%
= 0.29 × 0.24 + 0.71 × 0.05
= 0.0696 + 0.0355
= 0.1051
The probability is 0.1051.

f a 10 percent reduction in price leads to a 20 percent increase in quantity demanded, the coefficient of elasticity of demand would be equal to _______
The coefficient of elasticity of demand would be equal to 2 .
The price elasticity of demand for a good determines how responsive the desired amount is to the price (PED).
When prices rise, demand declines for almost all products, but some products are more negatively impacted than others. When a price increases by 1% while all other factors remain constant, the price elasticity provides the percentage change in quantity required. If the elasticity is 2, a 1% increase in price results in a 2% drop in the amount sought. The effect of changes in other variables on the necessary quantity is measured by various elasticities.We know that the coefficient of elasticity of demand is given by
ED = Change in demand(percent) ÷ change in price (percent)
ED = 20% ÷ 10% = 2
Hence the coefficient of elasticity of demand would be equal to 2 .

Consider the equation 6 – x = 3 – x. The picture shows the graphs of y = 6 – x and y = 3 – x. Which statement is true?
The two lines never intersect (are parallel lines) thus the equation:
6 - x = 3 - x
Has no solutions.
What can we say about the equation?
Here we have the equation:
6 - x = 3 - x
And (supposedly) a graph of the two lines:
y = 6 - x
y = 3 - x
Notice that the part on the linear equations that depens of x is equal to the ones in the equation above.
So basically we have a system of equations:
y = 6 - x
y = 3 - x
Because "y" is the same thing in both equations, we can rewrite:
6 - x = y = 3 - x
If we remove the part in the middle, we return to the original equation:
6 - x = 3 - x
Now, the solution of that equation is given by the point where the two graphs of the linear equations intersect, it will never happen, because both linear equations are parallel (have the same slope) which means that the equation:
6 - x = 3 - x
Has no solutions.

Find the equation of the linear function represented by the table below in slope-intercept form.X1234y-3-7-11-15
Answer:
The equation of the linear function represented in the table is y = -4x + 1.
Explanation:
Since the values in the x-variable are consecutive, let's take a look at the y-values.
Let's determine the common difference of the y-values.
[tex]\begin{gathered} -15-(-11)=-4 \\ -11-(-7)=-4 \\ -7-(-3)=-4 \end{gathered}[/tex]As we can see, the common difference between the y-values is -4. Therefore, the slope of the equation is -4.
To determine the y-intercept, let's subtract -4 from -3 to determine the y-value at x = 0.
[tex]-3-(-4)=1[/tex]Hence, the y-intercept is 1.
Therefore, the equation is y = -4x + 1.

A) What is the unit rate of 1 candy bar?
B)How many bars must Annie sell to make $75?
Answer:
A) $1.5
B)50 bars
Step-by-step explanation:
A) First find out how much money one bar costs: 18/12= 1.5
$1.5 is how much one costs
B) Now that you know how much one bar costs, divide 75 by 1.5 to determine how many bars you need to get to $75.
75/1.5=50
50 bars to get to $75

the digits 3,4,5,6,7 and 8 are randomly arranged to form a three-digit number. (Digits are not repeated.) Find the probability that the number is even and greater than 800.
The probability of getting an even number greater than 800 is 0.08
Total outcomes possible when a three-digit number is formed without repetition:
Using the digits 3,4,5,6,7 and 8:
The first digit can be filled in using any of the 6 options
The second digit can be filled using the remaining 5 options
The third digit can be filled in using the remaining 4 options
So, total outcomes possible = 6*5*4 = 120 possibilities
Now, finding even number greater than 800:
The first digit can only be filled by 8 for a number to be greater than 800 which means there is only one option for the first digit
The second digit can be filled using any of the remaining options except 8 which means there are 5 options
The last digit can be filled using 4 and 6 because these are the only even numbers which mean 2 options
Total possible outcomes = 1*5*2 = 10 possibilities
The probability that the number is even and greater than 800:
= 10/120 = 0.08

The sum of the angles on a straight line is 180 degrees. This means that
angle MJO + angle NJO = 180
From the information given,
angle MJO = 131
angle NJO = 15x + 4
Thus,
131 + 15x + 4 = 180
135 + 15x = 180
15x = 180 - 135 = 45
x = 45/15
x = 3
We would substitute x = 3 into angle NJO = 15x + 4
angle NJO = 15 * 3 + 4 = 45 + 4
angle NJO = 49
