290 is 10 times as much as?

katrin2010 [14]

I'm pretty sure it's 29 . . . A way to remember is that when you multiply a number by ten, add a zero. For example, 34 x 10 is 340. Just add the zero!

A marketing research consultant hired by Coca-Cola is interested in determining if the proportion of customers who prefer Coke t

wlad13 [49]

Answer:

A one-tailed hypothesis will be used to perform the test.

Step-by-step explanation:

The purpose of the marketing research consultant hired by Coca-Cola is to determine whether the the proportion of customers who prefer Coke to other brands is over 50%.

The marketing research consultant selected a random sample of n = 200 customers. The sample proportion of people who favored Coca-Cola over other brands was 55%.

The marketing research consultant can perform a single proportion hypothesis test to determine whether greater than 50% of customers prefer Coca-Cola to other brands.

Since we need to determine whether the population percentage is greater than a null value, the hypothesis is not two-tailed.

The hypothesis can be defined as:

H₀: The proportion of people who favor Coca-Cola over other brands was 55%, i.e. p = 0.50.

Hₐ: The proportion of people who favor Coca-Cola over other brands was more than 55%, i.e. p > 0.50.

Thus, a one-tailed hypothesis will be used to perform the test.

Hailey is scuba diving in the ocean. Her boat is anchored 300 feet away at a 30° angle of depression. If her diving partner is 2

Marianna [84]

Answer:

the answer is actually 313 ft not a single person has answered the correct answer... smh

Explanation:

313 ft

sinΘ = opp/hyp

Hailey's depth: x = 300sin30 = 150

partner's depth = 150 + 25 = 175

then, find horizontal distance

300^2 = 150^2 + b^2

b = 150 x square root of 3

then,

c^2 = (150 x square root of 3)^2 + (175)^2

c = 313.25

Relate a vertical line test to understanding functions.

timofeeve [1]

Answer:

Hello,

I am not sure if you are still having an issue with this problem but for future reference for you or anyone else the answer is

d. Each vertical line drawn through the graph will intersect a function in only one location.

I thought of it this way:

"Each vertical line" which tells me only one line per "one location" now I could be completely off but this was just my logic and it helped me personally.

Zane received a quote to move his belongings to his new house. The estimate from

erik [133]

9514 1404 393

Answer:

packing: $50 per hour
loading: $75 per hour
packing LCM: 12; loading LCM: 15

Step-by-step explanation:

We can let P and L represent the hourly costs of packing and loading, respectively. The two estimates can be represented by the equations ...

6P +5L = 675

4P +3L = 425

The LCM of the coefficients of P is LCM(6, 4) = 12.

The LCM of the coefficients of L is LCM(5, 3) = 15.

Each LCM is the product of the numbers, divided by their greatest common factor. For 4 and 6, the product is 24, and both even numbers have a factor of 2, so the LCM of 4 and 6 is 24/2 = 12. The numbers 3 and 5 have no common factors, so the LCM is simply their product.

_____

The LCM is useful if you're going to solve the equations by "elimination". Here, the LCM of 12 means we can eliminate P by making its coefficient be 12 in both equations. Multiplying the first equation by 2, we can subtract 3 times the second equation to eliminate P:

2(6P +5L) -3(4P +3L) = 2(675) -3(425)

12P +10L -12P -9L = 1350 -1275

L = 75 . . . . . simplify

Similarly, we can eliminate L by making its coefficients be 15.

5(4P +3L) -3(6P +5L) = 5(425) -3(675)

20P +15L -18P -15L = 2125 -2025

2P = 100 . . . . simplify

P = 50 . . . . . . divide by 2

The hourly rates are ...

$50 per hour for packing

$75 per hour for loading
