Answer:
8
Step-by-step explanation:
We start by getting the coordinate of the dilated point
what we simply have to do
here is to multiply the coordinates of the initial given point by the dilation factor
Mathematically, we have this as ;
(4,1) to (8,2)
So the x-coordinate of the endpoint is 8

Trevor is interested in purchasing the local hardware/electronic goods store in a small town in South Ohio. After examining accounting records for the past several years, he found that the store has been grossing over $850 per day about 60% of the business days it is open. Estimate the probability that the store will gross over $850 at least 6 out of 10 business day
Answer:
P( at least 6 out of 10 business days ) = 0.6312
Step-by-step explanation:
Given the data in the question;
p = 60% = 0.6
q = 1 - p = 1 - 0.6 = 0.4
Using Binomial distribution;
P( X = r ) =
where
we substitute
P( at leas 6 ) = P(6) + P(7) + P(8) + P(9) + P(10)
= [¹⁰C₆ × 0.6⁶ × 0.4⁴] + [¹⁰C₇ × 0.6⁷ × 0.4³] + [¹⁰C₈ × 0.6⁸ × 0.4²] + [¹⁰C₉ × 0.6⁹ × 0.4¹] + [¹⁰C₁₀ × 0.6¹⁰ × 0.4⁰]
= [0.250] + [0.214] + [0.1209] + [ 0.0403] + [ 0.00604 ]
= 0.6312
Therefore, P( at least 6 out of 10 business days ) = 0.6312
Given:
The regression equation is:
The given point is (17,3.8).
To find:
The residual for the given point.
Solution:
We have,
Substituting , we get
The predicted value at is 11.
The given point is (17,3.8). It means the observed value at is 3.8.
Formula for residual:
Residual = Observed value - Predicted value
Residual =
Residual =
Therefore, the residual for the given point is -7.2.
Answer: The answer is y = -1/2184
Answer:
10 years
Step-by-step explanation:
Find 5% of $1200 and then divide that number by 600
1200 x 0.05 = 60
600/60 = 10
