Lovely Lawns, Inc., intends to use sales of lawn fertilizer to predict lawn mower sales. The store manager estimates a probable six-week lag between fertilizer sales and mower sales. The pertinent data are:
Period Fertilizer Sales Number of Mowers Sold
1 1.6 12.0
2 1.3 10.0
3 1.8 13.0
4 2.0 15.0
5 2.2 15.0
6 1.5 11.0
7 1.6 12.0
8 1.4 10.0
9 1.8 13.0
10 1.4 10.0
11 1.9 15.0
12 1.4 11.0
13 1.7 14.0
14 1.4 13.0
a. Determine the correlation between the two variables. Does it appear that a relationship between these variables will yield reasonable predictions?Explain.
b. Obtain a linear regression line for the data.
c. Predict expected lawn mower sales for the first week in August, given fertilizer sales six weeks earlier of 2 tons.
Answer:
R = 0.8815 ;
y = 6.14679X + 2.33028 ;
14.624
Step-by-step explanation:
Using an online correlation Coefficient calculator, the correlation Coefficient, R between the number of lawn fertilizer sold and the number of lawn mowers sold is 0.8815. This R value depicts a strong positive correlation between both variables.
The regression line equation obtained by Plotting the values to generate a linear model is :
y = 6.147X + 2.330
With ;
Slope or gradient being 6.147
Intercept = 2.330
C.)
x = 2
y = 6.147X + 2.330
y = 6.147(2) + 2.330
y = 14.624
You deposit $10,000 in an account that pays 5.88% annual interest. Find the balance after 2 years when the interest is compounded monthly
Answer:
The above calculator compounds interest monthly after each deposit is made. Deposits are applied at the beginning of each month. If you want to make deposits at the end of each month, then please subtract the first deposit from the initial savings amount.

You are estimating the cost of optical sensors based on the resolution of the sensor. You decide to calculate the coefficient of determination (R2) as part of determining the goodness of fit of an equation. Using the preliminary calculations below, calculate the R2 and determine its meaning.
Summation of (Yi - Ybar)2 = 147172
Summation of (Yhat - Ybar)2 = 130542
Summation of (Y - Yhat)2 = 16630
a. 88.70% of the variation in the cost is being explained by the resolution.
b. 88.70% of the variation in the resolution is being explained by the cost.
c. 11.30% of the variation in the resolution is being explained by the cost.
d. 11.30% of the variation in the cost is being explained by the resolution.
Answer:
a. 88.70% of the variation in the cost is being explained by the resolution.
Step-by-step explanation:
Given :
Summation of (Yi - Ybar)2 = 147172
Summation of (Yhat - Ybar)2 = 130542
Summation of (Y - Yhat)2 = 16630
The Coefficient of determination (R²) :
Sum of Square regression (SSR) / sum of square TOTAL (SST). It gives the percentage of the dependent variable which can be explained by the regression line.
Cost is the dependent variable in this scenario.
SSR = Summation of (Yhat - Ybar)2 = 130542
SST = Summation of (Yi - Ybar)2 = 147172
Hence,
SSR / SST = 130542 / 147172
R² = 130542 / 147172
R² = 0.8870029 = (0.8870029 * 100%) = 88.7%
Which multiplication problem does the model represent?
Answer:
2/3 * 1/3 = 2/9
Step-by-step explanation:
You see the top 2 lines being shaded which is 2/3's of the whole square.
The second shaded part only covers 1/3 of the whole square.
Thus, you multiply both parts to figure out the darkest shaded part!
Subjective probability has little use in the real world.

Step-by-step explanation:
The value of a certain stock has decrease 5% per day for the past 10 days. The initial price of the stock was $30 per share. Which equation describes the value of the share price of the stock as a function of n the number of days elapsed during the 10 days period?
Your answer is:
V(n) = 30(0.95)^n
Why?
Well here is why!
Rate of decrease = 5%
Period, n = 10 days
Initial stock price = $30
Value of share price as a function of n:
Value, V(n)
Initial price = A
V(n) = Initial price(1 - rate)^n
V(n) = 30(1 - 0.05)^n
V(n) = 30(0.95)^n

Write an equation for the nth term of the arithmetic sequence. Then find a 30
-9, -6, - 3,0, ...
Answer:
The nth term is given by: [tex]a_n = -9 + 3(n-1)[/tex]
The 30th term is 78.
Step-by-step explanation:
Arithmetic sequence:
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term and d is the common difference between terms.
-9, -6, - 3,0
This means that [tex]a_1 = -9, r = -6 - (-9) = -6 + 9 = 3[/tex]. So
[tex]a_n = -9 + 3(n-1)[/tex]
30th term:
[tex]a_30 = -9 + 3(30-1) = -9 + 87 = 78[/tex]
The 30th term is 78.

Evaluate 4x+2 when x=6 .please answer I'm being timed
Answer:
26
Step-by-step explanation:
first, substitute the value for x into the expression. since x = 6, you will be plugging in 6 for x.
4x + 2 ⇒ 4(6) + 2
simplify the expression, starting with 4 · 6.
4(6) + 2 ⇒ 24 + 2
then add 24 + 2.
24 + 2 ⇒ 26

Answer:
a = 0.3
b = 0.4
c = 40%
d = 15%
Step-by-step explanation:
There are a total of 10 tick marks. So we know that 1 tick mark = 10%
a has 3 tick marks so you can say it's 0.3
b has 4 tick marks so you can say it's 0.4
c also has 4 tick marks, but it's asking for the percentage, so you get 40%
d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%
a chord subtends an angle of 34 at the center of a circle of radius 4cm find the length of the chord (take =22/7)
Answer:
2.34 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle at the centre (θ) = 34°
Radius (r) = 4 cm
Length of chord (C) =?
The length of the chord can be obtained as follow:
C = 2rSine(θ/2)
C = 2 × 4 × Sine(34/2)
C = 8 × Sine 17
C = 8 × 0.2924
C = 2.34 cm
Therefore, the lenght of the chord is 2.34 cm.
Given m ||n, find the value of x.
+
(x+18)
(5x-6)°
Answer:
x = 28
Step-by-step explanation:
(x + 18)° + (5x - 6)° = 180° (supplementary angles)
Solve for x
x + 18 + 5x - 6 = 180
Add like terms
6x + 12 = 180
6x = 180 - 12 (subtraction property of equality)
6x = 168
x = 168/6 (division property of equality)
x = 28

Two professors are applying for grants. Professor Jane has a probability of 0.61 of being funded. Professor Joe has probability 0.29 of being funded. Since the grants are submitted to two different federal agencies, assume the outcomes for each grant are independent. Give your answer to four decimal places.
Required:
a. What is the probability that both professors get their grantsfunded? Give your answer to four decimal places.
b. What is the probability that at least one of the professors will befunded? Give your answer to four decimal places.
c. What is the probability that Professor Jane is funded but ProfessorJoe is not? Give your answer to four decimal places.
d. Given at least one of the professors is funded, what is theprobability that Professor Jane is funded but Professor Joe is not?
Answer:
a) 0.1769 = 17.69% probability that both professors get their grants funded.
b) 0.7231 = 72.31% probability that at least one of the professors will be funded.
c) 0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.
d) 0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not
Step-by-step explanation:
a. What is the probability that both professors get their grants funded?
Jane has a 0.61 probability of being funded.
Joe has a 0.29 probability of being funded.
So
[tex]p = 0.61*0.29 = 0.1769[/tex]
0.1769 = 17.69% probability that both professors get their grants funded.
b. What is the probability that at least one of the professors will be funded?
None:
Jane has a 1 - 0.61 = 0.39 probability of not being funded.
Joe has a 1 - 0.29 = 0.71 probability of not being funded.
0.39*0.71 = 0.2769
At least one:
1 - 0.2769 = 0.7231
0.7231 = 72.31% probability that at least one of the professors will be funded.
c. What is the probability that Professor Jane is funded but Professor Joe is not?
Jane has a 0.61 probability of being funded.
Joe has a 1 - 0.29 = 0.71 probability of not being funded.
0.61*0.71 = 0.4331
0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.
d. Given at least one of the professors is funded, what is the probability that Professor Jane is funded but Professor Joe is not?
0.4331/0.7231 = 0.5989
0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not
