A consumer organization estimates that over a 1-year period 17% of cars will need to be repaired once, 7% will need repairs twice, and 4% will require three or more repairs. What is the probability that a car chosen at random will need
Answers
The probability that a car chosen at random will need no repairs = 72%; no more than one repair = 91%; some repairs = 9%
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty.
28% of all vehicles will require some sort of repair; of these, 19% will require one repair, 7% will require two repairs, and 2% will require more than two repairs.
The number of vehicles that would not require any form of repairs is equal to the entire number of vehicles less the proportion that requires repairs; for example, 100% - 28% = 72%. The total number of automobiles minus the percentage that require more than one repair equals the percentage of vehicles that will require no repairs or just one
; hence, 100% - (7% + 2%) = 91%. The total number of vehicles in need of repairs is equal to the product of those with two repairs and those with three or more.

A line passes through the points (-2,8) and (5,-20)
Answers
The linear equation that passes through these two points is:
y = -4x
How to find the equation for the line?A general linear equation can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that the line passes through two known points (x₁, y₁) and (x₂, y₂), then we can write the slope as:
a = (y₂ - y₁)/(x₂ - x₁)
Here we know the two points (-2, 8) and (5, -20), so the slope is:
a = (-20 - 8)/(5 + 2) = -28/7 = -4
So the line is:
y = -4*x + b
To find the value of b, we can replace the values of the point (-2, 8), so we will get:
8 = -4*(-2) + b
Now we can solve this for b.
8 = -4*(-2) + b
8 = 4*2 + b
8 = 8 + b
8 - 8 = b
0 = b
Then the linear equation is:
y = -4*x

A farmer sells eggs at a market. She offers three different sizes.
For any size, the weight of each egg can vary up to 8%.
Calculate the missing values in the table.
Is it possible for an egg to be both large and extra large?
Yes
Answers
The missing values in the table can be calculated by multiplying the given weights by 0.92 and 0.88 to get the maximum and minimum weights for each size.
Small egg:
Minimum weight = 1.2 * 0.92 = 1.104 ounces;
Maximum weight = 1.2 * 1.08 = 1.296 ounces
Medium egg:
Minimum weight = 1.6 * 0.92 = 1.472 ounces;
Maximum weight = 1.6 * 1.08 = 1.728 ounces
Large egg: Minimum weight = 2 * 0.92 = 1.84 ounces; Maximum weight = 2 * 1.08 = 2.16 ounces
Extra Large egg: Minimum weight = 2.4 * 0.92 = 2.208 ounces; Maximum weight = 2.4 * 1.08 = 2.592 ounces
Yes, it is possible for an egg to be both large and extra large, as long as the weight of the egg is between 1.84 and 2.592 ounces.

Here the 10th term of this arithmetic sequence is 999.
What is an arithmetic sequence in math?An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k. In a geometric sequence, each term rises by dividing by or multiplying by a certain constant k.A series of integers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15.Using the method for locating the nth term, we may locate a particular term in an arithmetic series. Step 1: An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d. Therefore, enter the numbers a = 2 and d = 3 into the formula to determine the nth term.Given data :
an = n³ - 1
a1 = 1³ - 1 = 1 - 1 = 0
a2 = 2³ - 1 = 8 - 1 = 7
a3 = 3³ - 1 = 27 - 1 = 26
a4 = 4³ - 1 = 64 - 1 = 63
a5 = 5³ - 1 = 125 - 1 = 124
a10 = 10³ - 1 = 1000 - 1 = 999
I saw that these numbers were one less than the cubes. So the answer is

Answer:
e This die appears to be fair because the proportion of sixes fluctuates greatly.
Step-by-step explanation:
For a fair die, we would expect the proportion of sixes to be approximately 1/6 = 0.167. Because the observed proportion is not the same as 0.167, we have reason to suspect that the die is not fair.

We can automatically eliminate C and D, since we have determined going down. We know it's also not A because if the correlation is constant, then all the dots would be lined up, and not scattered around.

Answers
The ratio of spice A to spice B is : 49/87
Here, 2 1/3 grams of spice A was mixed with 4 1/7 grams of spice B.
First we convert the improper fraction into a proper fraction.
For improper fraction2 1/3,
2 1/3
= (2 × 3)/3 + 1/3
= 6/3 + 1/3
= (6 + 1)/3
= 7/3 which is a proper fraction.
and for 4 1/7
= (4 × 7)/7 + 1/7
= 28/7 + 1/7
= (28 + 1)/7
= 29/7
The ratio of spice A to spice B would be,
(2 1/3) / (4 1/7 )
= (7/3) / (29/7)
= (7/3) × (7/29)
= (7 × 7)/(3 × 29)
