PLEASE HELP MEEEEE!!!! I WILL GIVE YOU BRAINLIST AND POINTS

Mathematics
1 answer:
Sloan [31]3 years ago
3 0

When you multiply numbers with the same base and exponents, you just add the exponents together. In the case of the first question:

11^{2} * 11^{7} = 11^{9}

When dividing, subtract the exponents instead, and when there's an exponent outside the parentheses the way it is on the 3rd question, multiply them together.

Hope this helps! :)

The are of a rectangular community the graden is 300 square feet. The length of a rectangular graden is three times its width. F
Keith_Richards [23]

Answer:

  • length: 30 ft
  • width: 10 ft

Step-by-step explanation:

The description of the garden fits that of 3 squares arranged side-by-side. The area of each of those would be 100 ft², so their side length would be ...

  s = √A= √(100 ft²) = 10 ft

This dimension is the width of the garden, whose length is 3 times this amount.

The length and width of the garden are 30 ft and 10 ft, respectively.

Find the missing side lengths
Mashcka [7]

Answer:

y = 9√3

x = 18

Step-by-step explanation:

taking 30 as reference angle

b = y

p = 9

h = x

so

tan30 = p/b

1/√3 = 9/b

or, b = 9√3

so

h^2 = p^2 + b^2\\x^2 = 9^2 + y^2\\or, x^2 = 81 + (9\sqrt{3} )^2\\or, x^2 = 81 + 243\\or, x ^2 = 324\\or, x =\sqrt{324} \\\\so x = 18

A researcher is interested in determining if the more than two thirds of students would support making the Tuesday before Thanks
klio [65]

Answer:

a. p = the population proportion of UF students who would support making the Tuesday before Thanksgiving break a holiday.

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they are in favor of making the Tuesday before Thanksgiving a holiday, or they are against. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

So, the binomial probability distribution has two parameters, n and p.

In this problem, we have that n = 1000 and p = \frac{700}{1000} = 0.7. So the parameter is

a. p = the population proportion of UF students who would support making the Tuesday before Thanksgiving break a holiday.

Describe how you would test a sample of food to show it contains protein.
harkovskaia [24]

Step-by-step explanation:

Iodine test for starch

Method:

Place one spatula of the food sample on a dish or 1 cm3 if the sample is liquid.

Using a dropper, place a few drops of iodine solution onto the food.

Record any change in the colour of the solution.

Starch is detected using iodine solution. This turns blue-black in the presence of starch.
