Complete the equation of the line whose interpret is (9.0) and slope is -2. Remember to use y=mx+b format
kenny6666 [7]

Answer:

y = - 2x + 18

Step-by-step explanation:

Step 1:

y = mx + b          Slope Intercept Form

Step 2:

y = - 2x + b         Input Slope Value

Step 3:

0 = - 2 ( 9 ) + b           Input x and y values

Step 4:

0 = - 18 + b        Multiply

Step 5:

b = 18          Add 18 on both sides

Answer:

y = - 2x + 18

Hope This Helps :)

A random sample of 38 wheel chair users were asked whether they preferred cushion type A or B, and 28 of them preferred type A w
-BARSIC- [3]

Answer:

The statement that cushion A is twice as popular as cushion B cannot be verified

Step-by-step explanation:

From the question we are told that:

Sample size n=38

Type a size A X_a=28

Type a size B X_b=10  

Generally the probability of choosing cushion A P(a) is mathematically given by

P(a)=\frac{28}{38}

P(a)=0.73

Generally the equation for A to be twice as popular as B is mathematically given by

P(b)+2P(b)=3P

Therefore Hypothesis

Null H_0: p \leq \frac{2P}{3P} \\Altenative H_A:p>\frac{2P}{3P}

Generally the equation normal approx of p value is mathematically given by

z=\frac{x-np_0-0.5}{\sqrt{np_0(1-p_0)} }

z=\frac{28-(38*2/3)_0-0.5}{\sqrt{38*2/3*1/3} }

z=0.75

Therefore from distribution table

Pvalue=1-\theta (0.75)

Pvalue=0.227

Therefore there is no sufficient evidence to disagree with  the Null hypothesis H_0

Therefore the statement that cushion A is twice as popular as cushion B cannot be verified

PLEASE ANSWER WITH SOLUTION PLS
katen-ka-za [31]

Answer:

whatever% of anything, is just (whatever/100) * anything.

there were a total of 560000 votes, now, off those some are valid and some are invalid.

we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.

how many are the valid ones anyway?  well, 85% of 560000, which is just (85/100) * 560000.

we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?

well, (75/100) * [ (85/100) * 560000 ].

Step-by-step explanation:

First and foremost, we should not that:

1 yard = 3 feet

We are informed that Wyatt uses 200 feet of rope for each doormat and that he wants to make 25 doormats.

The expression that shows a correct way to find how many yards of rope he needs will be:

= (200 × 25) / 3

= 5000/3

= 1666.67 yards
