Answer:
-1.28
Step-by-step explanation:
You would put these two equations into a graphing ccalculator:
y = -4x - 1
and
y= 5^x + 4
Wherver they intersect is your answer.
These two happen to intersect at (-1.28,4.13)
Since the equation has x-values, you would give the first number (x-coordinate) as your answer.
If y=10x+0.08

Hey! Hoped I helped Im Eve btw Have an amazing day and consider marking this brainliest please. If you do thank you in advanced.
Answer:
58 degrees
Step-by-step explanation:
A triangle is 180 degrees total. 60+62= 122. 180-122= 58. The last angle is 58

She needs a little less than 4 pounds to make 12 turkey burgers because 1/3 times 12 is about 3.99 pounds. But she only has 3 3/8 pounds which is about 3.375 pounds.
Answer:
10 burgers
Step-by-step explanation:
[tex]{3.375pounds}(\frac{12 burgers}{3.99pounds})=(\frac{xburgers}{3.375pounds}){3.375pounds}\\xburgers=10.15\\[/tex]
so you get 10 burgers
or you could approach it
[tex]\frac{3.375}{(1/3)} =[/tex]3.375×3=10.125

Answer:
y = 1/2x + 1.5
Step-by-step explanation:
first find the slope and then put it in y= x+b
you can see that to get from (-1,1) to (1,2) you must go up one and over two
slope is = rise over run --> rise 1 and run 2
the b is were it hit threw the y intercept
Part B: You can also find the standard deviation for the binomial probability distribution of a specific outcome in a binomial experiment. Use the formula to find the standard deviation. You've already identified n and p in Part A. Show your work, and round your answer to two decimal places.
Answer:
Mean = np + n(n-1)p²
Standard Deviation= √ σ² = √npq
Step-by-step explanation:
The m.g.f of the binomial probability distribution b(x;n,p) is derived as below.
M₀t = E (e)^tx
= ∑(e)^tx (nCx) (p)^x q^(n-x) { x varies from 0 to n}
= ∑(e)^tx (nCx) (pe^t)^x q^(n-x)
= (q +pe^t)^n
The expansion of this binomial is purely algebraic and need not to be interpreted in terms of probabilities.
WE get the moments by differentiating M₀(t) once, twice, etc. with respect to t and putting t=0
Thus
μ₁` = E(X) = [ d/dt (q +pe^t)^n] t=0
= [ npe^t (q +pe^t)^n-1] t=0
= np
And
μ₂` = E(X²) = [ d²/dt² (q +pe^t)^n] t=0
= [ npe^t (q +pe^t)^n-1] + [ n(n-1)p²e^²t (q +pe^t)^n-2] t=0
= np + n(n-1)p²
Variance= μ₂= μ₂` - μ₁`²
σ² =E(X²)- E(X)²
σ² =np + n(n-1)p²- (np )²
σ² =npq
Standard Deviation= √ σ² = √npq

Consider the probability distribution shown below. x 0 1 2 p(x) 0.15 0.60. 0.25 compute the expected value of the distribution.
Answer:
1.10
Step-by-step explanation:
Given the probability distribution :
x : ___ 0 ___ 1 ___ 2
p(x)__0.15 _0.60 __0.25
The expected value is obtained by:
Σ(X * p(x))
(0 * 0.15) + (1 * 0.60) + (2 * 0.25)
0 + 0.60 + 0.50
= 1.10
