-8 - 5 = -13
_____ ___

-5 + 5 = 0

So there is no slope because it’s a vertical line. It stays on the x-axis since there was no change in x-values.

The equation would simply be x=-5, and there is no slope.

The equation for slope formula is
(y2-y1)/(x2-x1)

I hope this helped its a little confusing yes

For 2 people, you can give 5 to one, and 5 to the other, equally split from 10

For 3 people, you can give each person 3 whole candies, and 1/3 of the remaining 1 candy that is left to split between three people (3 tiny pieces for the 3 people

And for 4 people, you can give each one 2 whole candies, and 1/2 of the remaining candies to all four people (2 candies, when split in half is 4 in total) !!

Steve makes the tree diagram shown to find the possible outcomes of tossing a penny, a nickel, and a dime. What is the probabili

stiks02 [169]

Hi there!

Since there is a 50% chance of any coin landing on heads and a 50% chance of any coin landing on tails, the chance that all 3 coins land on either heads or tails (the same side) is 50% * 50% * 50%.

50% * 50% * 50%
= 0.5 * 0.5 * 0.5
= 0.25 * 0.5
= 0.125

Now, we need to convert into a percentage:

0.125 = 12.5%

So, the answer is 12.5%.

Hope this helps!

National statistics show that 23% of men smoke and 18.5% of women smoke. A random sample of 175 men indicated that 45 were smoke

NeTakaya

Answer:

98% C.I. = [-0.1270, 0.0994]

Step-by-step explanation:

Here

p1= proportion of men smokers

p1= 45/175= 0.2571

p2= proportion of women smokers

p2= 42/155= 0.2709

1) Choose the significance level ∝= 0.02

2) The formula for confidence interval is

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

and

(p1^- p2^) z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

<u>3) The z value is 2.05</u>

<u>4) Calculations:</u>

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(-2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=-0.1270 ( using calculator)

And

(p1^- p2^)z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=0.0994 ( using calculator)

and Putting ± 2.05 in the confidence interval formula we get limits (-0.1270, 0.0994)

(-28)-(3) i dont itjhggh

Nitella [24]

Hey there! I'm happy to help!

We have the number -28 and we are subtracting 3 from it. This means we are going even further into the negatives, so it is -31.

Have a wonderful day! :D
