Hector waters his lawn if it does not rain at least 1 1/2 inches each week. It has already rained 3/8 inch this week. Which inequality represents the number of inches of rain, r, still needed so Hector does not have to water his lawn this week?A. r ≥ 1 7/8
B. r > 1 7/8
C. r ≥ 1 1/8
D. r > 1 1/8
(The fractions are mixed numbers!!!!)

Answer:
the answer is C
Step-by-step explanation:
this is because he needs at least 1 1/2, it's already rained 3/8 inches, so to simplify the equation change 1 1/2 to 1 4/8 which is still equivalent to 1 1/2, then subtract 3/8 from 1 4/8 which will give you 1 1/8. now here is where it gets kind of tricky, both C and D seem to have 1 1/2, but the difference between them is the symbols > and ≥ are CRUCIAL!!!! (">" means that the number at the left is greater than the number at the right while "≥" means that the number at the left is greater than OR EQUAL TO the number at the right) so as you can see you also need to pay attention to what the text says, because it is mention quote on quote "Hector waters his lawn if it does not rain at least 1 1/2 inches each week," this means that if it's not at least (in other words the same as or more) 1 1/2 inches of rain a week, he will water his plants

56. 6x = 132
x = 22
57. 2/3 = -8x
-24x = 2
x = -2/24= -1/12
58. 5/11x = 55
5x = 605
x = 121
59. 4/5 = 10/16x
4/5 = 5/8x

for that two lines be parallel the condition is that two slope be equal m1 = m2
Now you must calculate with point givens both slope , with the following formula
m= y2-y1/ x2-x1, for the firsts two points P( -7,0) and Q( 6,-5)
m = -5-0/6-(-7) , m = -5/13
for the seconds points R (-1,-1) and S( 0,-4)
m = -4-(-1)/ 0-(-1) = -3/1 = -3
the lines are not parallel, m1 ≠ m2

Answer:
You need to Choose a 0.01 significance level , instead of 0.05 significance level.
Step-by-step explanation:
Consider the provided information.
It is given that type I error has been committed.
Type I error occur, if we rejected the null hypothesis even null hypothesis is true.
We reject the null hypothesis if p-value < α
Accept the null hypothesis if p-value ≥ α
According to given condition the value of α is 0.05 that means 95% chance that your assumption is correct and 5% chance that assumption is wrong.
In order to reduce the risk of this error you need to increase the significance level so that the value of α becomes lower than the p value.
lower α means you will be less likely to detect a true difference if one really exists.
Hence, you need to Choose a 0.01 significance level , instead of 0.05 significance level.

Answer:
The x -coordinate(s) of the point(s) of intersection of these two polynomials are
The sum of these x -coordinates is
Step-by-step explanation:
The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).
Thus, and we solve for x
Using Zero Factor Theorem: = 0 if and only if = 0 or = 0
The solutions are:
The sum of these x -coordinates is
We can check our work with the graph of the two polynomials.

Answer: m=50w
Step-by-step explanation:
When you divide 900 by 18, you get 50.
Since we are trying to find the amount of minerals per worker, m is the first variable. w is the second because that is the number of workers you can get with the minerals Scarlett has.
So you would do 900÷18 to get the amount each worker is worth, which would be 50 minerals.
