Vaselesa [24]3 years ago

Answer:

No, the probability of choosing a red marble is not the complement of choosing a blue marble.

P(red) + P(blue) = 3/5, not 1.

The number of blue and red marbles does not add to the total number of outcomes.

There are other marbles besides red ones and blue ones.

Answer:

Below is the sample response

Step-by-step explanation:

The complementary event for choosing a red marble is choosing a blue or purple. The total number of marbles is 5. The probability of choosing a red marble is 1/5, and the complement would be 4/5. That is not the same as choosing a blue marble.

If F(x)=4x-1 and g(x)=x^2+7, what is g(f(x))
VashaNatasha [74]
Answer

g(f(x)) = = 16 {x}^{2} - 8x + 8

step by step Explanation

The functions given are

f (x)= 4x- 1

g(x)= {x}^{2} + 7

We want to find:

g(f (x))= g( 4x- 1)

This implies that

g(f (x))= ( (4x- 1)^{2} + 7)

Let us now simplify

( {a - b)}^{2} = {a}^{2} -2ab + {b}^{2}

This implies that

( (4x- 1)^{2} + 7) =( {(4x)}^{2} - 2(4x) \times 1 + 1

Combine the terms to get,

= 16 {x}^{2} - 8x + 1 + 7

= 16 {x}^{2} - 8x + 8

You are looking at two area rugs for your bedroom. One is a square with a side length of 6.3 feet. The other is a rectangle that
Dmitry [639]
-----------------------------------------------------------------
Square Rug
-----------------------------------------------------------------
Area = Length x Length
Area = 6.3 x 6.3
Area = 39.69 ft²

-----------------------------------------------------------------
Rectangle Rug
-----------------------------------------------------------------
Area = Length x Width
Area = 4.8 x 8.2
Area = 39.36 ft²


39.69 ft²  is bigger than 29.36 ft², so the square rug is bigger.

-----------------------------------------------------------------
Ans: The Square Rug covers a greater area

Jason's two test scores in English are 87 and 91. What must he score on the third test to get an average test score of 92 or bet
irga5000 [103]

You first find the average of the first two test scores. When you find the average, you add the two numbers together and then divide by two which gives you 89. You then plug in different scores above the number 89 and find the average of those (89 and x) to see which gives you an average of 92. It’s mostly a guess and check type of problem.
