$p(x)=2x^4-3x^2+x-1\\\\
Substitude\ p=-1\ into\ equation\\\\
p(-1)=2x^4-3x^2+x-1=2*(-1)^4-3(-1)^2-1-1=\\2*1-3*1-2=2-3-2=-3\\Answer\ p(-1)=-3$

the calorie cafe is known for their hotdogs and burgers. the number of calories in a burger is 220 more than the number of calor

meriva

Answer:

Number of calories in burger = 620 calories

Number of calories in hotdog = 400 calories

Step-by-step explanation:

Number of calories in burger = x

Number of calories in hotdog = y

y = x - 220

x + 2y = 1,420

Substitution:

x + 2 * (x - 220) = 1,420

x + 2x - 440 = 1,420

3x = 1,420 + 440

x = 1,860 / 3

x = 620 calories

y = x - 220

= 620 - 220

= 400 calories

the employees of a company were surveyed on questions regarding their educational background ( college degree) and marital statu

Llana [10]

Number employees N = 600

Then

Probability of Single + College degree = ?

Probability of single S = 100/600 = 1/6

Probability of College graduate G = 400/600 = 2/3

So then probability of both S and G is

Prob Single or Graduate = 1/6 + 2/3 = 1/6 + 4/6 = 5/6

. = 0.833

Then answer is

Probability of Single or Graduate = 5/6= 0.8333

Is also 83.33%

1a. Split the larger piece(1/3) into half to show the two pieces
1b. Both are 3/6 or 1/2
2a. It shows 1/2 +1/4
2b.cut it so there are 3 1/4 pieces, so cut the 1/2 piece horizontally in the middle
2c. 2/4 + 1/4 = 3/4. 1/2 + 1/4 = 3/4
