Manuel wants to earn at least $44 trimming trees. He charges $6 per hour and pays $4 in equipment fees. What are the possible numbers of hours Manuel could trim trees? Use (t) for the number of hours. Write your answer as an inequality solved for (t).
Given:
Manuel wants to earn at least $44 trimming trees.
He charges $6 per hour and pays $4 in equipment fees.
To find:
The possible numbers of hours Manuel could trim trees.
Solution:
Let t be the numbers of hours Manuel could trim trees.
Earnings of Manuel in one hour = $6
Earnings of Manuel in t hour = $6t
He pays $4 in equipment fees. So, we will subtract this from the income.
[tex]\text{Total earnings}=6t-4[/tex]
Manuel wants to earn at least $44 trimming trees. It means, total earnings must be greater than or equal to 44.
[tex]6t-4\geq 44[/tex]
[tex]6t\geq 44+4[/tex]
[tex]6t\geq 48[/tex]
Divide both sides by 6.
[tex]t\geq \dfrac{48}{6}[/tex]
[tex]t\geq 8[/tex]
Therefore, the required number of hours must be greater than or equal to 8 hours.

A student has a business selling snowballs during the summer. For each snowball the student sells, they makes a profit of $1.50. On the hottest day of the summer, the student sold 125 snowballs and made a profit of $187.50. Create a model in point slope form to represent the profit the student makes, y, based on the number of snowballs sold, x. Use mathematics to justify your answer.
Answer:
y = $1.25x
Step-by-step explanation:
Given that :
Profit made per sale = $1.50
Number of sales made on hottest day of summer = 125 ; Profit made = $187. 50
Let profit Made = y
Number of snowballs sold = x
Profit made = profit made per snowball sold * Number of snowballs sold
y = $1.25x
$187.50 = $1.25(125)
The weight of laboratory grasshoppers follows a Normal distribution, with a mean of 90 grams and a standard deviation of 2 grams. What percentage of the grasshoppers weigh between 86 grams and 94 grams?
A. 99.7%
B. 95%
C. 68%
D. 47.5%
E. 34%
Answer:
95%
Step-by-step explanation:
Do the math it's pretty easy.
When the weight of laboratory grasshoppers follows a normal distribution, with a mean of 90 grams and a standard deviation of 2 grams, 95% of grasshoppers weigh between 86 and 94 grams.
What is normal distribution?Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Let W be the sample of weight of laboratory grasshoppers.
W follows N(90, 2)
To calculate P(86 < W < 94)
[tex]P ( 86 < W < 94 ) \\\\P ( \frac{86 - 90}{2} < \frac{W - 90}{2} < \frac{94 - 90}{2} )\\\\P(-2 < Z < 2)\\[/tex]
= 95% (approximately)

The amount of snow on the ground when the storm started is the y- intercept of graph which is 5 inches.
The y- intercept of a graph gives the value y when the value of x = 0.
The y - intercept is the point where the plotted line intersects the y - axis. This is a reasonable value because, the point 0 depicts the time the snow started to fall. The y - axis represents the amount of snow on the ground in inches, therefore, the value on the y-axis when x = 0, should give the appropriate answer. Hence, amount of snow when the snow started was 5 inches.Learn more : https://brainly.com/question/1354826?referrer=searchResults

The national percentage of automobile accident fatalities that are alcohol related is 39%. In a random sample of 96 automobile accident fatalities in the state of Connecticut, 44 were alcohol related. Is this sufficient evidence to say that Connecticut has a higher percentage of alcohol related automobile fatalities?
Answer:
Step-by-step explanation:
Given that:
There are 96 automobile accident fatalities in Connecticut and 44 were alcohol related.
The null hypothesis and the alternative hypothesis for this study can be computed as:
[tex]H_o: P =0.39 \\ \\ H_1:P> 0.39[/tex]
The sample proportion [tex]\hat p[/tex]= 44/96 = 0.45833
Using the Z formula for a single proportion test, we get;
[tex]Z = \dfrac{\hat p - P }{\sqrt\dfrac{{P(1-P)}}{{n}}}[/tex]
[tex]Z = \dfrac{0.45833 - 0.39 }{\sqrt\dfrac{{0.39(1-0.39)}}{{96}}}[/tex]
[tex]Z = \dfrac{0.06833 }{\sqrt\dfrac{{0.39(0.61)}}{{96}}}[/tex]
[tex]Z =1.37[/tex]
The p-value = 1 -P(Z< 1.37)
The p-value = 1 - 0.9147
The p-value = 0.0853
At the level of significance (∝) 0.05 ;
Since p-value is greater than level of significance (∝); we accept the null hypothesis and conclude that there is no sufficient evidence to say that higher percentage of alcohol is related to automobile fatalities.
