Given: AB=BC, D is the midpoint of AB, and E is the midpoint BC. Prove: AD=BE

Answers

Answer:

Using mid point theorem, A line segment joining the mid points of the two sides of the triangle, is equal to half the length of the third side.

D and E are the mid points. Hence,

DE=

(6.4)

DE=3.2cm

Answer:

AD=BE

Step-by-step explanation:

Because AB and BC are equal, their lengths are also equal and also it is an Isosceles triangle. Therefore the midpoint of AB or the half of AB which is either AD or DE are equal. Vice versa for BC. So AD=BE

In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate. On election day, 51% of voters actually voted for the Republican presidential candidate. (a) Identify the value of the sample proportion.

Answers

Answer: 0.48 .

Step-by-step explanation:

The sample proportion is a ratio of number of successes in a sample to the sample size.

Let p be the proportion of voters actually voted for the Republican presidential candidate.

Given: In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate.

Sample proportion: [tex]\hat{p}=\dfrac{48}{100}=0.48[/tex]

Elliot collects miniature toy cars. He wants to fill 4 display cases.each display case holds 15 cars. He has 28 cars now, and he is able to buy 3 more every month with the money he saves from his allowance. How many more months will it be until elliot has enough cars to fill all 4 display cases?

Answers

Answer:

Elliot has to wait 11 months before he has enough cars

Step-by-step explanation:

Elliot has 4 display cases with each case being able to hold 15 cars. Thus we know

total # of cars Elliot can place in his display case = 4 * 15 = 60 cars

From this, we can figure out how many more cars Elliot needs by subtracting the amount of cars he already has

# of cars Elliot needs = 60 - 28 = 32 cars

Now to find the number of months Elliot needs, we divide by how many he can buy each month

# of months Elliot needs to save up for = 32 / 3 = 10 2/3

Assuming Elliot does not get his allowance until the end of the month, we will have to round the number of months up to the nearest integer, 11

The residual for a predicted relative abundance when the rainfall was 3 inches is 1.25. What is the actual relative abundance when the rainfall was 3 inches

Answers

Answer:

The actual relative abundance will be "7.59".

Step-by-step explanation:

The residual on something like a curve anywhere at a point becomes expressed as the maximum at either the position between some of the real y-value as well as the expected y-value. Consequently, the difference regarding true relative abundance as well as expected relative abundance seems to be 1.25 whether we presume that the x-variable represents rainfall, as well as they-variable, represents the relative abundance of locusts.

The predicted relative abundance for 3 inches rainfall will be:

= [tex]6.7 - (0.12\times 3)[/tex]

= [tex]6.34[/tex]

The residual will be:

= [tex]actual - predicted \ relative \ abundance[/tex]

= [tex]1.25[/tex]

Now,

The actual relative abundance will be:

= [tex]1.25 + predicted \ relative \ abundance[/tex]

= [tex]1.25 + 6.34[/tex]

= [tex]7.59[/tex]

Remember that perhaps the residual positive value means that even the calculation underestimates the relative abundance. The real relative abundance, however, is 7.59.

Gym Ratsby c.safosStage Set: Late in the evening in the Hammer House Boxing Gym, most of the regulars have left. A scattered few people still remain. In the background, a man uses a jump rope. A woman does push-ups. (CAIN, a small boxer, sits on a bench unwrapping the protective tape off of his knuckles and wrists using his teeth. SERGIO, his sparring partner and best friend, cuts away at the tape on CAIN'S other hand.)SERGIO: I know you've got a hand in there somewhere.CAIN: (spitting the tape out of his mouth) Well, remember to stop cutting once you see bone. (The people exercising in the background finish their workouts and move off stage, leaving the focus of the audience on CAIN and SERGIO.)SERGIO: Right, like you'd be able to feel it otherwise. I don't even think you have bone in there. I think you've got anvils in your hands.CAIN: Are you kidding? I'll need more than anvils come fight night. Doerkson is a monster in the ring. To bring him down, I'll need a lead pipe and a tank if you can spare them. (Freed from the cast of protective tape, CAIN'S hands start to violently shake. CAIN closes them into a fist until they calm.)SERGIO: What was that? (CAIN stands up and walks over to a nearby heavy bag and starts to throw light jabs.)CAIN: It's nothing, just nerves. It'll calm down after the fight.SERGIO: Have you seen a doctor? (CAIN'S light jabs get heavier.)CAIN: Seriously, I'm fine. Just nerves.SERGIO: You don't get nerves. You don't get worried or stressed. I know you. What's going on? (CAIN'S heavy jabs get heavier as the heavy bag begins to sway.)CAIN: I'm fine. Let it go.SERGIO: You can't stonewall me. We're going to a doctor tonight. I don't want to see you end up like Motts, stumbling around, shaking, can't even hold a spoon to eat, let alone throw hands.

If they step in, they'll cancel the fight. They do that and I'm out of a purse. I need that money! And if you call yourself my friend, you'll keep quiet.
