HELP PLZ!!! Michelle owns a clothing store that designs T-shirts and shorts. She sells

Mathematics

bixtya [17]3 years ago

Answer: B

Step by Step: If it takes 2 hours to design shorts to get $15 and 1 hours to make shirts for $8 you can multiply 8 by 2 and get 16 which is more than 15. The reason you multiply 8 by 2 is because it takes 2 hours to make 1 pair of shorts. With this you then multiply 16 by 9 which gives you 144.

Hope this helps

Determine parallel, perpendicular, or neither!
Leviafan [203]
Rearrange Line 1 and Line 3’s equations in the form of y = mx + c for easier comparison.

Lines 1 and 2 are parallel, because they have the same gradient.

Lines 1 and 3, and 2 and 3 are neither, because their gradients do not multiply to form -1.
(Gradients of perpendicular lines multiply to form -1.) c

LabTech is a company that manufactures microscopes and other laboratory instruments . On occasion, one of the microscopes is def
Scrat [10]

Answer:

0.0782 (7.82%)

Step-by-step explanation:

The required probability will be found by using the Binomial Distribution which fits the case of n independent events each with a probability of success equal to p with k successes.

The PMF (Probability Mass Function) is

f(k,n,p)=\binom{n}{k}p^kq^{n-k}

Where q = 1-p

LabTech states that the probability that a microscope is defective is 0.17%, p=0.0017, q=0.9983. We need to know the probability that k=1 microscope is defective out of a set of n=50 of them. We now apply the formula

f(1,50,0.0017)=\binom{50}{1}0.0017^10.9983^{49}=0,0782

Which means that there is a 7.82% of probability to get 1 defective microscope out of the first 50

Yasmin purchased 6 heads of cabbage that each weighed  pounds. How much did the cabbage weigh all together?
MakcuM [25]
The weight of each cabbage is not given.
I'll assume that each cabbage weighs p pounds.

Now, we know that Yasmin bought 6 cabbage each weighing p pounds. To know the total weight, we will simply multiply the number of cabbages by the weight of each as follows:
Total weight = 6 * p = 6p pounds

Hope this helps :)
