Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. Wh

en he starts his shift, the water level shows 4 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups?

Answer: 158.331 minutes.

Step-by-step explanation: To solve this problem we need to replace the given level of water (64 cups) in the equation, and isolate and calculate the time (t):

W=-0.414t+129.549

isolating t:

W-129.549=-0.414t

t=(W-129.549)/-0.414

replacing W=64

t=(64-129.549)/-0.414

t=-65.549/-0.414

t=158.331 minutes.

A plant is already 55 centimeters tall, and it will grow one centimeter every month. The plant's height, (in centimeters), after
monitta

The plant's height after 34 months will be 89cm if the plant is already 55 centimeters tall.

<h3>What is meant by height?</h3>

Height is defined in mathematics as the vertical distance from the object's top to its base. It is occasionally referred to as 'altitude.' The term height in geometry refers to the measurement of an object along the y-axis in coordinate geometry.

Height and elevation all refer to the vertical distance between the top and bottom of something or between a base and anything above it. Height refers to something measured vertically, whether it be high or low.

Given, the relation between the height and the months is:

H(m)=55+m

Now, we have to find the height of the plant after 34 months.

So, we substitute m=34 in the expression to obtain height,

H(m)=55+m

H(34)=55+34

H(34)=89cm

Hence the height will be 89cm

Life tests performed on a sample of 13 batteries of a new model indicated: (1) an average life of 75 months, and (2) a standard
Alja [10]

Answer:

The lower limit of the 90% confidence interval for the population mean life of the new model is 72.53 months.

Step-by-step explanation:

Our sample size is 13.

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

df = 13-1 = 12

Then, we need to subtract one by the confidence level \alpha and divide by 2. So:

\frac{1-0.90}{2} = \frac{0.10}{2} = 0.05

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 12 and 0.05 in the t-distribution table, we have T = 1.782.

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

s = \frac{5}{\sqrt{13}} = 1.3868

Now, we multiply T and s

M = T*s = 1.782*1.3868 = 2.47

The lower end of the interval is the mean subtracted by M. So it is 75 - 2.47 = 72.53

The lower limit of the 90% confidence interval for the population mean life of the new model is 72.53 months.
