Answer:

y = 3x -5

Explanation:

Since it's parallel, it will have the same slope: 3.

So you'll have y = 3x + a, and we need to find a.

Plug in the values for the point we are given:

7 = 3(4) + a

7 = 12 + a

a = -5

<h3>So there you have it: y = 3x - 5</h3>

Answer:

y=3x-5

Step-by-step explanation:

y=3x+6

since the line is parallel, the slope will be the same (but y int is still unsolved)

so plug in x,y from (4,7) in y=mx+b or y-y1=m(x-x1)

i used y=mx+b

7=3(4)+b

7=12+b

b=(-5)

so the final answer is y=3x-5

Answer:

Probability of stopping the machine when $X < 9$ is 0.0002

Probability of stopping the machine when $X < 10$ is 0.0013

Probability of stopping the machine when $X < 11$ is 0.0082

Probability of stopping the machine when $X < 12$ is 0.0399

Step-by-step explanation:

There is a random binomial variable $X$ that represents the number of units come off the line within product specifications in a review of $n$ Bernoulli-type trials with probability of success $0.91$ . Therefore, the model is ${15 \choose x} (0.91) ^ {x} (0.09) ^ {(15-x)}$ . So:

$P (X < 9) = 1 - P (X \geq 9) = 1 - [{15 \choose 9} (0.91)^{9}(0.09)^{6}+...+{ 15 \choose 15}(0.91)^{15}(0.09)^{0}] = 0.0002$

$P (X < 10) = 1 - P (X \geq 10) = 1 - [{15 \choose 10}(0.91)^{10}(0.09)^{5}+...+{15 \choose 15} (0.91)^{15}(0.09)^{0}] = 0.0013$

$P (X < 11) = 1 - P (X \geq 11) = 1 - [{15 \choose 11}(0.91)^{11}(0.09)^{4}+...+{15 \choose 15} (0.91)^{15}(0.09)^{0}] = 0.0082$

$P (X < 12) = 1- P (X \geq 12) = 1 - [{15 \choose 12}(0.91)^{12}(0.09)^{3}+...+{15 \choose 15} (0.91)^{15}(0.09)^{0}] = 0.0399$

Probability of stopping the machine when $X < 9$ is 0.0002

Probability of stopping the machine when $X < 10$ is 0.0013

Probability of stopping the machine when $X < 11$ is 0.0082

Probability of stopping the machine when $X < 12$ is 0.0399

Jonathon paid $237 for 15 pizzas, which included the $12 delivery charge. How much will he pay for 22 pizzas

RUDIKE [14]

237-12=225=cost of 15 pizzas without delivery charge
225/15=15=cost per pizza
15*22=$330=cost of 22 pizzas

Tresset [83]

A) 0.2076
B) 0.6786
C) 0.3214

Explanation:
A) $P(X=5)=_8C_5(0.75)^5 \times(1-0.75)^{8-5}
\\
\\=_8C_5(0.75)^5 \times (0.25)^3=0.2076$
B) We find the probability that X=6, 7, or 8:
$P(X=6)=_8C_6(0.75)^6(0.25)^2=0.3115
\\
\\P(X=7)=_8C_7(0.75)^7(0.25)^1=0.267
\\
\\P(X=8)=_8C_8(0.75)^8(0.25)^0=0.1001
\\
\\0.3115+0.267+0.1001=0.6786$
C) P(X≤5) = 1-P(X>5) = 1-0.6786 = 0.3214

Can anyone help and show work

Romashka [77]

Answer:

x=88⁰

Step-by-step explanation:

Since the value of that angle is 44⁰ and the angle is located on the circle, the measure of the arch x is twice the angle value.

So x=2×44⁰=88⁰
