8. Which statement can be represented by the equation shown?<br> 9x-2=8x

Thepotemich [5.8K]

Answer:

A or the 1st one

Step-by-step explanation:

Angelo is making 9 dollars per hour but, loses 2 dollars due to the bus fee. So in math form that would be:

9x - 2

And the second part is Tom makes 8 dollars per hour but doesn't have to pay for bus fee. In math form that would be;

So put that together that would be

9x - 2 = 8x

Marina86 [1]

Answer:

36 fries

Step-by-step explanation:

Michael has a probability of 0.3.

Lidia has a probability of 0.1.

Alexandra has the probability of 0.32.

Catherine has the probability of 0.1.

Let the probability of Ronald be x

Sum of all the probabilities must be 1

So, $0.3+0.1+0.32+0.1+x=1$

$0.82+x=1$

$x=0.18$

So, probability of Ronald is 0.18

We are given that here are 200 fries in the basket.

So, the number of fries that Ronald will eat = $0.18 \times 200 =36$

Hence Ronald will eat 36 fries.

Umnica [9.8K]

Answer:

88.51 is the minimum score needed to receive a grade of A.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 73

Standard Deviation, σ = 11

We are given that the distribution of exam grades is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.0793.

$P( X \geq x) = P( z \geq \displaystyle\frac{x - 73}{11})=0.0793$

$= 1 -P( z \leq \displaystyle\frac{x - 73}{11})=0.0793$

$=P( z \leq \displaystyle\frac{x - 73}{11})=0.9207$

Calculation the value from standard normal z table, we have,

$P(z \leq 1.410) = 0.9207$

$\displaystyle\frac{x - 73}{11} = 1.410\\x =88.51$

Hence, 88.51 is the minimum score needed to receive a grade of A.

If a line slope of -1/2 contains the point (2,3), then it must also contain which of the following points?

tiny-mole [99]

Before the fraction: -1/2, i have a negative sign
use y=mx+b
3=-1/2(2)+b
3+1=-1+b+1
4=b
check your work
0=-1/2x+4
0+4=-1/2x
(4)÷(-1/2)=(-1/2x)÷(-1/2)
-2=x
another pair is (-2,0) use this to figure out the other points, and/or the points you have in the multiple choice.
