You have a bag of marbles that has 3 blue marbles and 4 red ones. What is the chance that you pick a blue OR a red marble?

nikdorinn [45]

Answer:

7/7

Step-by-step explanation:

Add up the amount of the marbles in total and read what color the marble they ask for the chances of. The color of marble should go first then the total of the marbles. (they could ask for more than one color so just add up both the colors given.)

The function t(x) = 3x + 1 determines how many cans of green beans a food truck needs to stock on board, where x is the number o

mash [69]

Answer: The amount of money he must be spent when the crew is going to work 2 shifts is $11.

Step-by-step explanation:

Since we have given that

the function t(x)=3x+1 determines how many cans of green beans a food truck needs to stock on board , where x is the number of shifts the crew is going to work in the truck.

And the function c(x)= x+4

Since the crew uses c(t(x)) to find the amount of money to spend on green beans .

So, we will use "Composition of functions ":

$c(t(x))=(3x+1)+4\\\\c(t(x))=3x+5$

Since the crew is going to work 2 shifts , so our answer will be

$c(t(2))=3(2)+5\\\\c(t(2))=6+5\\\\c(t(2))=11$

Hence, the amount of money he must be spent when the crew is going to work 2 shifts is $11.

For which pair of functions is (gºf)(a) =la|-2

nikklg [1K]

Answer:

<h2> The third</h2>

Step-by-step explanation:

$(g\circ f)(x) = g\big(f(x)\big)$

so:

$I.\quad (g\circ f)(a)=\sqrt{f(a)}=\sqrt{a^2-4}=\sqrt{(a+2)(a-2)}\\\\II.\quad (g\circ f)(a)=2f(a)-2=2(\frac12a-1)-2=a-2-2=a-4\\\\ \bold{III.\quad (g\circ f)(a)=\sqrt{f(a)-5}-2=\sqrt{5+a^2-5}-2=\sqrt{a^2}-2=|a|-2}\\\\ IV.\quad (g\circ f)(a)=4f(a)-5=4(3-3a)-5 = 12-12a-5=-12a+7$

If the equation of a circle is (x + 5)2 + (y - 7)2 = 36, its center point is

Trava [24]

Answer:

B

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 5)² + (y - 7)² = 36 ← is in standard form

with (h, k ) = (- 5, 7 ) → B

Mario is making dinner for 9 people. Mario buys 6 containers of soup. each container is 18 ounces. if everyone gets the same amo

Olenka [21]

First you multiply 6 and 18 to find the total servings: 6*18= 108. Then you divide 108 by 9 to see how many servings each person gets: 108/9= 12. Therefore, each person get 12 ounces of soup.
