The grocery store makes a 32% profit on deli foods. The profit for the
deli last month was $640. What was the total sales for the deli last
month?
Answer:
$2000
Step-by-step explanation:
The profit is the money earned by the store, meaning in this case, it's 32%. 32 percent of an amount is equal to 640. Set up an equation: 0.32(x) = 640, where x is the total money earned including the profit. x is solved to be 2000 dollars.
someone please help I’ll make you BRAINLIST
Answer: x=2√3
sin θ= opposite side ÷ hypotenuse
sin 30°= √3÷ x
sin 30°= 1/2
Therefore,
1/2= √3÷x
1/2×x=√3÷x×x
x is cancelled off on the right hand side,
1/2×x=√3
1/2× x ×2=√3×2
1/2 and 2 cancel off on the left hand side,
x= 2√3

Honey is a technology company that provides online coupons to its subscribers. Honey's analytics staff has developed a classification method to predict whether a customer who has been sent a coupon will apply the coupon toward a purchase. For a sample of customers, the following table lists the classification model's estimated coupon usage probability for a customer. For this particular campaign, suppose that when a customer uses a coupon, Honey receives $1 in revenue from the product sponsor. To target the customer with the coupon offer, Honey incurs a cost of $0.05. Honey will offer a customer a coupon as long as the expected profit of doing so is positive. Using the equation
Expected Profit of Coupon Offer = P(coupon used) × Profit if coupon used + (1 - P(coupon used)) × Profit if coupon not used
determine which customers should be sent the coupon.
Customer Probability of Using Coupon
1 0.47
2 0.35
3 0.27
4 0.03
5 0.08
Determine the expected profit for each customer. Round your answers to the nearest cent. Enter negative value as negative number, if any.

, so these customers

the coupon
Based on the expected profit to Honey, and the probability of the various customers using the coupons, all customers except customer 4 should be sent coupons.
What is the expected profit for all customers?The profit to Honey if people use the coupons is:
= Revenue - Cost
= 1 - 0.05
= $0.95
The profit if the coupon is not used is the cost of $0.05.
Customer 1 expected profit:
= P(coupon used) × Profit if coupon used + (1 - P(coupon used)) × Profit if coupon not used
= (0.47 x 0.95) + ( (1 - 0.47) x -0.05)
= $0.42
Customer 2 expected profit:
= (0.35 x 0.95) + ( (1 - 0.35) x -0.05)
= $0.30
Customer 3 expected profit:
= (0.27 x 0.95) + ( (1 - 0.27) x -0.05)
= $0.22
Customer 4 expected profit:
= (0.03 x 0.95) + ( (1 - 0.03) x -0.05)
= -$0.02
Customer 5 expected profit:
= (0.08 x 0.95) + ( (1 - 0.08) x -0.05)
= $0.03
In conclusion, all customers expect customer 4 should be sent the coupons as they result in profits.

A $1250 TV is on sale for $200 off the regular price. The tax is 5.5%. What is the total
cost of the TV with tax?
Answer: Multiply 950 by 5.5
1250 - 200 = 950
950 x 5.5 = answer.
I am not sure though.
Answer:
1107.75
Step-by-step explanation:
1250-200=1050
10%x1050=105
5%=52.5
1%=10.5
0.5%=5.25
1050+52.5+5.25=1107.75

It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minutes per day that people spend standing or walking. Among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately Normally distributed with 376 minutes and standard deviation 70 minutes. The mean number of minutes of daily activity for lean people is approximately Normally distributed with 526 minutes and standard deviation 106 minutes. A researcher records the minutes of activity for an SRS of 6 mildly obese people and an SRS of 6 lean people.
Required:
a. What is the probability that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 410 minutes?
b. What is the probability that the mean number of minutes of daily activity of the 6 lean people exceeds 410 minutes?
Answer:
0.9963 is the probabilities that mean number of daily activity of 6 lean people exceed 410 minutes.
Step-by-step explanation:
Solution:
6 Mildly obese people exceed 410 minutes.
Given:
Mean = µ = 376
Standard deviation = ∂ = 70
n = 6
p (x> 410) = p (z > x - µ/ ∂ / √n)
= p (z > 410 – 376 / 70 /√6 )
= p (z > 1.185)
= 1 – p (z < 1.185)
= 1 – 0.38199
= 0.618
0.618 is the probability that the mean number of minutes of daily activity of 6 mildly obese people exceed 410 minutes.
6 lean people exceed 410 minutes:
Given:
Mean = µ = 526
Standard deviation = ∂ = 106
n = 6
=p(x > 410)
= p (z > x - µ/ ∂ /√n)
=p (z > (410 – 526 ) / 106 / √ 6 )
= p (z > - 2.67)
= p (z <2.68)
= 0.9963
0.9963 is the probabilities that mean number of daily activity of 6 lean people exceed 410 minutes.
