Answer: It will take her more than 9 weeks.
Step-by-step explanation:
If she already has $150 that will be constant and if she can save $45 per week the we will have the expression 45w where w is the number of weeks.
Together it will be 150 + 45w
Now the money has to be at least $560 so it will be
150 + 45w ≥ 560 Now solve for w
-150 -150
45w ≥ 410
w ≥ 9.1
Which means it will take 10 or more weeks t
The correct answer is A. Hope this helps.
16 × 35 = 560
560 + 960 = 1,520
1,520 / 19 = 80
80 / 16 = 5
Answer = 5
Hope this helped☺☺
Answer:
y=-3/4x-1
Step-by-step explanation:
y=mx+b; y is the y coordinate; m is the slope; x is the x coordinate; you have to find b. So you replace all the numbers out which is given to you;
-4=-3/4(4)+b (you multiply -3/4 by 4 and get -3)
-4=-3+b (you add 3 to both sides and get -1)
-1=b (you now found b so plug it into the equation)
y=-3/4x-1
By formula we know that:
z (x) = (x - m) / [sd / sqrt (n)]
where x is the value we want to know (6.7), m is the mean (5), sd is the standard deviation (7.1) and n is the sample size (29).
Replacing we have:
z (6.7) = (6.7 - 5) / [7.1 / sqrt (29)]
z = 1.289
If we look in the normal distribution table (attached), we have that the probability is 0.8997, therefore:
1 - 0.8897 = 0.1003
So the conditional probability of a herd sample earning at least 6.7 pounds per steer is 10.03%.
Now the hypothesis tells me:
m> 5
The probability is somewhat low, therefore, the most correct thing is to reject the hypothesis even though it is a fact that can occur.
