Liam has a summer job mowing lawns and shoveling. He earns $12 per hour mowing lawns and $18 per hour shoveling. Liam would like to earn at least $500 this summer. Write an inequality to model this situation.
The inequality is 12x + 18y ≥ 500 and , where x is the number of hours mowing lawns and y is the number of hours shoveling field
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the number of hours mowing lawns be x
Let the number of hours shoveling field be y
And , the amount earned per hour for mowing lawns = $ 12
So , for x hours , the amount earned = 12x
The amount earned per hour for shoveling = $ 18
And , for y hours , the amount earned = 18y
The minimum amount Liam should earn = $ 500
And , the inequality is
12x + 18y ≥ 500
Therefore , the value of A is 12x + 18y ≥ 500
Hence , the inequality equation is 12x + 18y ≥ 500

Answer:
B
Step-by-step explanation:
Step one: 1/2 * 2 = 1
The reason for this step is to make it 1 full cup of tomatoes like it says in the problem.
Step two: 1/8 * 2 = 2/8 = 1/4
The reason for this step is because you doubled the cup of tomatoes so you have to double the cup of onions.

Answer:
[tex]\frac{6}{4}[/tex]
Step-by-step explanation:
Use the following formula:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
([tex]x_1, y_1[/tex]) = (-4 , -4)
([tex]x_2 , y_2[/tex]) = (0 , 2)
Plug in the corresponding numbers to the corresponding variables:
(m) = [tex]\frac{2 - (-4)}{0 - (-4)} = \frac{2 + 4}{0 + 4} = \frac{6}{4}[/tex]
Your slope is [tex]\frac{6}{4}[/tex]. (Rise 6, Run 4)
~
Answer:
This means our slope is equal to [tex]\frac{6}{4}[/tex].
Step-by-step explanation:
Your ordered pairs are:
(-4, -4) and (0, 2)
To solve for the slope, we must use slope formula.
[tex]\frac{y2-y1}{x2-x1}[/tex]
Substitute:
[tex]\frac{2+4}{0+4}[/tex]
Solve:
[tex]\frac{6}{4}[/tex]
This means our slope is equal to [tex]\frac{6}{4}[/tex].

Wildlife biologists inspect 153 deer taken by hunters and found 42 of them carrying Lyme disease ticks. Calculate and interpret a 90% confidence interval for the proportion of deer that carry Lyme disease ticks.
Answer:
90 Confidence Interval for the proportion = [ 0.216,0.334]
Step-by-step explanation:
The confidence interval for proportion formula =
p ± z × √p(1 - p)/n
Where p = x/n
x = 42
n = number of samples = 153
p = 42/153
p = 0.2745098039 ≈ 0.275
z = z score of 90% confidence interval = 1.645
Confidence interval =
0.275 ± 1.645 × √0.275 - ( 1 - 0.275)/153
= 0.275 ± 1.645 × √0.0013031046
= 0.275 ± 0.0593820985
Confidence Interval
= 0.275 - 0.0593820985
= 0.2156179015
≈ 0.216
= 0.275 + 0.0593820985
= 0.3343820985
≈ 0.334
90 Confidence Interval for the proportion = [ 0.216,0.334]

y^0
Step-by-step explanation:
First simplify x^8y/x^-39
Which then gets you
x^47 y^-26'/x^14 y^-5 y^-21
Then you simplify x^47/x^14
Which gets you
x^33 y^26/y^-5 v^-21
Then simplify y^-26/y^-5
Which gets you afterwards
x^33/y^21 y^-21
Then you just simplify the numbers that are left x^33/y^21 y^-21
Then you get
X^33
(and since x^33 equals y^0 then)
Y^0

A student bought 3 boxes of pencils and 2 boxes of pens for $6. He then bought 2 boxes of pencils and 4 boxes of pens for $8. Find the cost of each box of pencils and each box of pens.
Answer:
.
Step-by-step explanation:
Each box of pens are valued at $1.50, thus for 2 boxers it would be 1.50 x 2 = $3. Thus, 2 boxes of pens = $3. Each box of pencils cost $1. therefore 3 boxes of pencils valued at $1 each = to $3. Final equation $3 + $3 = $6 for the first purchase. Using the same numbers we valued the 2 boxes of pencils at $1 each = $1 pencil box + $1 pencil box = $2 for 2 boxes. Then 4 pen boxes valued at $1.50 each = to $1.50 x 4 = $6 Final equation $6pen + $2pencil = $8 final

Published an article about a study in which researchers subjected laboratory gloves to stress. Among 216 vinyl gloves, 68% leaked viruses. Among 216 latex gloves, 6% leaked viruses. Using the accompanying display of the technology results, and using a .05 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1.
Answer:
The decision rule is
Reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the claim that the vinyl gloves have a greater virus leak rate than latex gloves
Step-by-step explanation:
From the question we are told that
The sample size of vinyl gloves [tex]n_1 = 216[/tex]
The sample size of latex gloves is [tex]n_2 = 216[/tex]
The sample proportion of vinyl gloves that leaked virus is [tex]\^ p_1 = 0.68[/tex]
The sample proportion of latex gloves that leaked virus is [tex]\^ p_2 = 0.06[/tex]
The significance level is [tex]\alpha =0.05[/tex]
The null hypothesis is [tex]H_o : p_1 = p_2[/tex]
The alternative hypothesis is [tex]H_a: p_1 > p_2[/tex]
Generally the number of vinyl gloves that leaked virus is
[tex]x_1 = \^ p_1 * n_1[/tex]
=> [tex]x_1 = 0.68 * 216[/tex]
=> [tex]x_1 = 146.88[/tex]
Generally the number of latex gloves that leaked virus is
[tex]x_2 = \^ p_2 * n_2[/tex]
=> [tex]x_2 = 0.06 * 216[/tex]
=> [tex]x_2 = 12.96[/tex]
Generally the pooled population proportion is mathematically represented as
[tex]\^ p = \frac{x_1 + x_2}{ n_1 + n_2}[/tex]
=> [tex]\^ p = \frac{146.88 +12.96 }{ 216 + 216}[/tex]
=> [tex]\^ p = 0.37[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \^ p_1 - \^ p_2}{ \sqrt{\^ p (1- \^ p ) [\frac{1}{n_1} + \frac{1}{n_2} ]} }[/tex]
=> [tex]z = \frac{ 0.68 - 0.06}{ \sqrt{0.37 (1- 0.37 ) [\frac{1}{216} + \frac{1}{216} ]} }[/tex]
=> [tex]z =13.35[/tex]
From the z table the area under the normal curve to the right corresponding to 13.35 is
[tex]P( Z > 13.35) = 0.00[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > 13.35)[/tex]
=> [tex]p-value = 2 * 0.00[/tex]
=> [tex]p-value = 0.00[/tex]
From the value obtained we see that [tex]p-value < \alpha[/tex] hence we have that
The decision rule is
Reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the claim that the vinyl gloves have a greater virus leak rate than latex gloves
