help me how to answer this please
Step-by-step explanation:
x^2 + 4x - 21 = 0
(x - 3)(x + 7) = 0
x = 3 or x = -7
x^2 - 14x = -24
x^2 - 14x + 24 = 0
(x - 12)(x - 2) = 0
x - 12 = 0 or x - 2 = 0
x = 12 or x = 2
2x^2 - 12 = 2x
x^2 - x - 6 = 0
(x - 3)(x + 2) = 0
x = 3 or x = -2

An oil company fills 1 over 12 of a tank in 1 over 3 hour. At this rate, which expression can be used to determine how long will it take for the tank to fill completely?
Answer:
4
Step-by-step explanation:
Don't let fractions fool you.
of a tank in an hour is equal to:
1/12 of a tank in 20 minutes.
Thus we know in an hour, an oil company can fill 3/12 of a tank (60 minutes in an hour).
3 x 4 = 12, and 12/12 = 1(a whole tank), so we multiply 1 (hour) by 4.
Our answer is that it takes 4 hours to fill a tank.
Answer:
it's 1/3 ⋅ 12 hours
or
3 ⋅ 12 hours

what is the rule for this table, IN -7,0,2,13,14,18. OUT -18,-11,-9,2,3,7
9514 1404 393
Answer:
y = x -11
Step-by-step explanation:
The table values don't have "nice" differences, so it is not easy to identify the pattern immediately. I found it worked to plot the points on a graph. This shows they are all on a line with a slope of 1. The point (0, -11) tells us that the y-intercept is -11.
A line with a slope of 1 and a y-intercept of -11 has the equation ...
y = x - 11
Which statement is true for all triangles with exterior angle 1 and remote interior angles 2 and 3?
Answer:
The answer is below
Step-by-step explanation:
The measure of the exterior angle 1 of a triangle is equal to the sum of the corresponding interior angles 2 and 3.
This is evident in the Theorem 3 of a triangle
For example
Given a hypothetical triangle, with the following angle QRS, ∠1, ∠2, and ∠3 are interior angles. And ∠4, ∠5, and ∠6 are the three exterior angles.
We have the following ∠4 = ∠2 + ∠3
∠5 = ∠1 + ∠3
∠6 = ∠1 + ∠2
Jackson is comparison shopping for orange juice. He created a table to help him decide which package was the best deal.Orange Juice Cost by PackagePackageCostCost per ounce10 oz bottle$1.99$0.19959 oz bottle$3.33$0.056489 oz bottle$4.99$0.0561Case of 2410 oz bottles$34.99$0.145864 oz carton$3.60$0.05625Jackson claims that the order of the best deal to the worst deal (based on cost/oz) is 10 oz bottle, 89 oz bottle, 59 oz bottle, case of 24 10 oz bottles, and 64 oz carton. Which statement about Jackson’s claim is true?Jackson is correct because he used the length of each decimal to compare the different costs. For example, 0.149 < 0.1457 < 0.05625.Jackson is correct because he compared values in equal place values to compare only the decimals with the same length. For example, 0.0561 < 0.0564 < 0.05625.Jackson is incorrect because he should compare the values in equal place values to compare all the decimals, not just those of the same length. For example, 0.0561 < 0.05625 < 0.0564.Jackson is incorrect because the case of 24 oz bottles is less per ounce than the 59 oz bottle and the 89 oz bottle. For example, 0.1457 < 0.0561 < 0.0564.

The starting salaries of individuals with an undergraduate degree from UC Riverside are normally distributed with a mean of $40,000 and a standard deviation of $5,000. What is the probability that a randomly selected individual with an undergraduate degree from UC Riverside will have a starting salary of $34,000 to $46,000?
Answer:
The probability that a randomly selected individual with an undergraduate degree from UC Riverside will have a starting salary of $34,000 to $46,000 is 0.7699.
Step-by-step explanation:
Let X denote the starting salaries of individuals with an undergraduate degree from UC Riverside.
It is provided that, [tex]X\sim N(\$40,000,\ \$5,000^{2})[/tex]
Compute the value of P (34000 < X < 46000) as follows:
[tex]P (34000 < X < 46000)=P(\frac{34000-40000}{5000}<\frac{X-\mu}{\sigma}<\frac{46000-40000}{5000})\\\\=P(-1.2<Z<1.2)\\\\=P(Z<1.2)-P(Z<-1.2)\\\\=0.88493-0.11507\\\\=0.76986\\\\\approx 0.7699[/tex]
Thus, the probability that a randomly selected individual with an undergraduate degree from UC Riverside will have a starting salary of $34,000 to $46,000 is 0.7699.

Which of the following quantities are continuous ?
Answer: A. only II
Step-by-step explanation:
Mathematics calculus differentiates things into discrete and continuous. Discrete things have indivisible units, the example will be how many dogs in a village. There is no half dog, it's either one, two, etc. But the distance covered by train can be written as half miles, it's the divisible unit.
The number of books and bracelets also discrete, thus the answer is A.
