The slope of the line with the coordinate points (-3, 9) and (1, 3) is -1.5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).
The given coordinate points are (-3, 9) and (1, 3).
Substitute, (x₁, y₁)=(-3, 9) and (x₂, y₂)=(1, 3) in the slope formula, we get
Slope = (3-9)/(1-(-3))
= -6/4
= -3/2
= -1.5
Therefore, the slope is -1.5.

A quality-control engineer samples 100 items manufactured by a certain process, and finds that 15 of them are defective. True or False:
a) The probability that an item produced by this process is defective is 0.15.
b) The probability that an item produced by this process is defective is likely to be close to 0.15, but not exactly equal to 0.15.
Answer: b) The probability that an item produced by this process is defective is likely to be close to 0.15, but not exactly equal to 0.15.
Step-by-step explanation:
Given that:
Number of samples = 100
Number of defective samples = 15
Proportion =number defective samples / total samples
P = 15 / 100 = 0.15
Hence, the probability that an item produces is defective is 0.15.
However, due to sampling Variations, the probability will be corrected for these variations. Hence, probability that an item produced by this process is defective is likely to be close to 0.15, but not exactly equal to 0.15.
Find the value of X. Round to the nearest 10th
Answer:
Step-by-step explanation:
You have to use the tangent.
Tan(y) = opposite / adjacent
tan(10) = x / 500
tan(10) = 0.1763
0.1763 = x / 500
500 * 0.1763 = x
x = 88.1635
x = 88.2
The Bayesian statistician Bruno de Finetti (1906–1985) began his 1973 book on probability theory with the declaration: "PROBABILITY DOES NOT EXIST." The capitals appeared in the original, so I imagine de Finetti wanted us to shout this statement. What he meant is that probability is a device for describing uncertainty from the perspective of an observer with limited knowledge; it has no objective reality. Discuss the globe tossing example from the chapter, in light of this statement. What does it mean to say "the probability of water is 0.7"?
Answer:
It means that if we select a random point around the globe, there is a 70% = 0.7 probability that it represents water.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
We know, that the planet Earth is formed 70% by water, and the globe represents this. This means, as the statement says, the if we select a random point around the globe, there is a 70% = 0.7 probability that it represents water.

The sum of two natural numbers is 17402. One of the two numbers is divisible by 10. If the units digit of that number is erased, the other number is obtained. What is the difference of these two numbers?
a) 10,272
b) 11,700
c) 13, 362
d) 14, 238
e) 15426
9514 1404 393
Answer:
d) 14,238
Step-by-step explanation:
Suppose the smaller number is n. If the larger number gives the smaller when it is divided by 10, then the larger number is 10n. The sum of the two numbers is ...
n + 10n = 11n = 17402 ⇒ n = 17402/11
The difference of the two numbers is ...
10n -n = 9n = (9)(17402/11)
This means the difference of the two numbers is 9/11 of the sum, so is ...
(9/11)(17402) = 14,238 . . . . matches D

two balls are chosen randomly from an urn containing 5 white, 3 black, and 2 orange balls. suppose that you win $2 for each black ball selected and you lose $1 for each white ball selected. what is the expected amount you will win from this game
Answer:
2.601
Step-by-step explanation:
Given that:
White balls, W = 5
Black balls, B = 3
Orange balls, O = 2
Total = (5 + 3 + 2) = 10
Winning = $2 for each black ball chosen
Winning = - $1 for each white ball
Sample space for making 2 selections ; order does not matter :
{WW, WO, WB, OO, OB, BB}
WW __WO __WB __OO ___OB __BB
-2 ____ - 1 __ 1 ____ 0 ____ 2 ___ 4
WW = 5C2 / 10C2 = 0.2222
WO = (5C1 * 2C1) / 10C2) = 0.222
WB = (5C1 * 3C1) / 10C2) = 0.3333
OO = (2C2) / (10C2) = 0.0222
OB = ((2C1) * (3C1)) / 10C2 = 0.1333
BB = 3C2 / 10C2 = 0.0667
Expected winning = Σx * p(x)
(-2 * 0.222) + (-1 * 0.222) + (1 * 0.333) + (0 * 0.022) + (2 * 0.133) + (4 * 0.667)
= 2.601

What is the area of the shaded region?
Answer:
66ft^2
Step-by-step explanation:
The lengths of plate glass parts are measured to the nearest tenth of a millimeter. The lengths are uniformly distributed with values at every tenth of a millimeter starting at 590.1, and continuing through 590.8. Determine the mean of the lengths. Mean (in tenths of millimeters) Round your answer to two decimal places (e.g. 98.76).
Answer:
The mean of the lengths is 0.35 tenths of millimeters
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and it's mean is given by:
[tex]M = \frac{a+b}{2}[/tex]
The lengths are uniformly distributed with values at every tenth of a millimeter starting at 590.1, and continuing through 590.8.
This means that [tex]a = 0, b = 590.8 - 590.1 = 0.7[/tex]
So, the mean is:
[tex]M = \frac{a+b}{2} = \frac{0 + 0.7}{2} = 0.35[/tex]
The mean of the lengths is 0.35 tenths of millimeters

The answer to this question depends on you understanding that both girls will be side by side when the second one catches the first. So the distances will be equal
That means that
.44t = 35t + 7.2 Subtract 0.35t from both sides
0.44t - .35t = 7.2
0.09 t = 7.2 Divide
t = 7.2/0.09
t = 80 minutes
How far apart are they from the starting point?
d = 0.44t
d = 0.44 * 80
d = 35.2 km from the starting point.
