Answer 1

9514 1404 393

Answer:

  A

Step-by-step explanation:

If the price of a hot dog is x, then the price of two hot dogs is 2x, and the price of 3 of them is 3x.

If the price of a drink is y, then the price of 2 drinks is 2y.

So, we have the price of 2 hotdogs and 2 drinks is 4.75.

  2x + 2y = 4.75

And the price of 3 hot dogs and 1 drink is 7.75.

  3x + y = 7.75

This pair of equations matches those in choice A.

_____

Comment on the question

We know right away that something is screwy here, because the cost of two hotdogs and 2 drinks should be an even number. 4.75 is not an even number. If we solve this set of equations, we find the cost of a drink is negative—not something you're likely to see in the real world.

So, this is an exercise in writing equations. It has nothing to do with finding real prices.

For all of the graphs:

Start the point on the number that I got from the inequality.

A filled circle means:

Greater than or equal to or less than or equal depending on where the line goes.

A hallow circle means:

Greater than or less than also depending on where the line is pointed towards too.

In order to graph an inequality you have to find and simply first then graph it.

For example on number 1, K ≤ -4.

Let's graph!

As you can see I filled in the circle and started at the point, -4.

Once I did it I made it bold from -4 and there on to the left. Making -4 be greater than or equal to K.

I showed that -4 is greater than or equal to K by making the line bold behind -4, also by filling in the circle.

Determine the value of the variable that makes the equation true.

The relationship between the length and weight of certain sea turtles can be approximated by the equation L = 0,55 W,
where L is the length in feet and W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?

Answers

Answer:

4.55 pounds

Step-by-step explanation:

From the above question , we are told that:

The relationship between the length and weight of certain sea turtles can be approximated by the equation

L = 0.55 W,

where

L is the length in feet

W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?

L = 2.5 feet

Hence,

2.5 = 0.55W

W = 2.5/0.55

W = 4.5454545455 pounds

Approximately, weight of the sea turtle in pounds = 4.55 pounds

Answers

Answer:

(a) 0.6

(b) 0.4

Step-by-step explanation:

If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made [tex]9+6=15[/tex] shots.

The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,

[tex]P([/tex]making a shot[tex])=\frac{9}{15}=\frac{3}{5}=0.6[/tex]

Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.

[tex]P([/tex]making a shot[tex])+P([/tex]missing a shot) [tex]=1[/tex]

[tex]P([/tex]missing a shot[tex])=1-P([/tex]making a shot[tex])[/tex]

[tex]P([/tex]missing a shot[tex])=1-0.6=0.4[/tex]

Answers

A six sided die has numbers 1 through 6 so getting a 7 is impossible so the probability would be 0 (impossible)

14 + 4 = 18 total boys and girls

Picking a girl would be 1/18 this is low so ( unlikely)

12 short and 12 long straws = 24 total straws. Picking a short one would be 12/24 = 1/2 this is in the middle ( neither likely nor unlikely)

20 + 6 = 26 total animals

Picking a bird = 20/26 = 10/13, this is high ( likely)
