You have a 1/2 chance of spinning an even number on the spinner, and a 1/2 chance of rolling an odd number on the die, 1/2 times 1/2 give you a 1/4 chance of doing both of those tasks.

Okay, The spinner had 8 equal parts, and there are 4 numbers -2,4,6,8, and the probability of spinning an odd number is 4/8 or 1/2. Also, the probability of rolling an odd number s 1/2. As a result, the probability of spinning an even number AND rolling an odd number is 1/4 or B. Hope it help!

Fill in the table using this function rule

stich3 [128]

1 = 20 (24-4(1)=20)
2 = 16 (24-4(2)=16)
5 = 4 (24-4(5)=4)
6 = 0 (24-4(6)=0)

I REALLY NEED HELP PLEASE

Nezavi [6.7K]

Answer:

Step-by-step explanation:

given

$\frac{s + ( - 7)}{ - 1}$

we first need to simplify the expression before we find it's value when s=-3

positive times negative=negative

so the equation becomes

$\frac{s - 7}{ - 1}$

substituting s=-3 into the equation.

$\frac{ - 3 - 7}{ - 1}$

$\frac{ - 10}{ - 1}$

=the negatives cancel out leaving

$= 10$

Dude is making 12 pounds of nut mixture with macadamia nuts and almonds. Macadamia nuts cost $9 per pound and almonds cost $5.25

pshichka [43]

Number of pounds of macadamia nuts is 8 pounds and number of pounds of almonds is 4 pounds.

<u>Step-by-step explanation:</u>

Step 1:

Given total pounds of mixture = 12 pounds, cost of macadamia nuts per pound = $9, cost of almonds per pound = $5.25, total cost of mixture per pound = $7.75.

Let number of pounds of macadamia nuts be x and number of pounds of almonds be 12-x.

Step 2:

Form an equation using the above information.

⇒ 9x + 5.25 (12-x) = 12 × 7.75

⇒ 9x + 63 - 5.25x = 93

⇒ 9x - 5.25x = 30

⇒ 3.75x = 30

⇒ x = 8

Number of macadamia nuts is 8 pounds.

Step 3:

Calculate number pounds of almonds

⇒ Number of pounds of almonds = 12 - x = 4 pounds.
