Answer:

6. 15/22

7. 1/12

9. 1/16

10. 0

Step-by-step explanation:

6. 10 of the 12 tiles are "not P", so the probability of a "not P" on the first draw is 10/12 = 5/6. After drawing a "not P" on the first draw, 9 of the remaining tiles are "not P". The probability of drawing one of those is 9/11. So, the joint probability of drawing two "not P" tiles is ...

(5/6)(9/11) = (5·9)/(6·11) = 15/22

7. The probability of drawing a tile worth 3 points is 3/12 = 1/4. The probability of drawing a tile worth 1 point is 4/12 = 1/3. So, the joint probability of drawing a 3-point tile, then a 1-point tile is ...

(1/4)(1/3) = 1/12

9. There are 3 of the 12 tiles worth more than 4 points. The probability of drawing one of them is 3/12 = 1/4. The probability of doing it again is also 1/4, so the probability of doing it twice is ...

(1/4)(1/4) = 1/16

10. The probability of drawing a Z is 1/12. Having drawn a Z, the probability of drawing a 10-point tile is 0/11. The joint probability of drawing a Z twice is ...

(1/12)(0/11) = 0

Answers

Answer:

She spent $10.12

Step-by-step explanation:

8.60*.07 = .602, round that to .60

8.60 + .60 = 9.2

solve 4 + x > 6 graph the solution

Answers

Answer:

Step-by-step explanation:

We know that (4 + x) is bigger than 6, so we have to find the answer that has more than 4. Since A and B both have answers that are more than 4, those are our options. But notice that A has one error, first lets define a closed circle and an open circle. A closed circle can mean it is greater than or equal to, it can also mean that it is less than or equal to. But an open circle means that it is either less than, or greater than. And because the equation has an open circle ( which is this sign >) it means that the answer is option B.

Here is a better picture of what a close circle and open circle look like:

In quadrilateral S T U V, the length of segment T U is unknown and represented by variable x, and the length of segment U V is twelve and three-tenths inches.

Answers

Answer:

6.6 inches

Step-by-step explanation:

4.1 times 3 = 12.3

2.2 times 3 = 6.6

I think this is right... sorry if not

Answer:

x = 6.6

Step-by-step explanation:

In order to solve the missing variable, we need to find the scale factor. I'll just take 12.3 and divide it by its corresponding side that is 4.1.

SF = 12.3/4.1 = 3

Now that we know the scale factor is 3, we can take 2.2 and multiply it by 3 to solve for x.

2.2(3) = 6.6

Therefore, x = 6.6.

Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
Can you please help?
the points (z,0) and (4,6) fall on a line with a slope of 6. What is the value of z?
If its not right im gonna report you

Answers

Answer:

z = 3

Step-by-step explanation:

First we want to find out how they found the slope of the line. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(6 - 0)/ (4 - z)

Simplify the parentheses.

= (6) / (4 - z)

Simplify the fraction.

= 6/(4 - z)

it is given that 6 is your slope. So let's add 6 to the left side of the equal sign.

6 = 6 / (4 - z)

To solve for z, we need to multiply both sides by (4 - z)

(4 - z)6 = 6

Now, divide both sides by 6 to isolate the expression of (4 - z)

4 - z = 1

Add z to both sides so it becomes positive.

4 = z + 1

Subtract 1 from both sides to isolate z.

3 = z

This is your answer.

Let's check it by plugging it back into the slope formula.

(6 - 0)/ (4 - z)

(6 - 0)/ (4 - 3)

= 6/1

= 6

Your answer is correct.

Hope this helps!

Answer:

8:05 pm (If you round to the nearest tenth place)

Step-by-step explanation:

basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.

1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes

1.7 minutes times 150 miles is 2 hours and 55 minuets

2 hours and 55 minutes plus 5:10pm is 8:05 pm

I'm so sorry if I'm wrong!

Answer: a) d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65 b: 6:41 pm

duration of time passed:

5:10 pm - 4:00 pm = 70 mins

distance = 65 miles

you points to use to make an equation:

(0,0) and (70,65) ---------------------> ( (0,0) is bc youre beginning the trip and you have no distance )

find the slope of your "future" equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{65}{70}[/tex] = [tex]\frac{13}{14}[/tex] = m

now use point-slope form

y - 65 = [tex]\frac{13}{14}[/tex] (x - 70)

y= [tex]\frac{13}{14}[/tex] (x - 70) + 65

and since it wants it in terms of d and t,

d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65

part b:

150 = [tex]\frac{13}{14}[/tex] (t - 70) + 65

85 = [tex]\frac{13}{14}[/tex] (t - 70)

85 = [tex]\frac{13}{14}[/tex] t - 65

150 = [tex]\frac{13}{14}[/tex] t

2100 = 13t

161.54 = t

about 162 minutes

Thennnn:

162/60 = 2 hours and 41 mins

4:00 pm + 2 hours and 41 mins = 6:41 pm

You are analyzing a scatter plot that has a negative correlation. What is true of the of the x and y values?

Answers

Answer:

As x increases, y decreases

Correlations on a scatter plot can either be positive or negative. When it has a negative correlation, it means the x values increases as the y values decreases.

There are basically two types of correlation on the scatter plot

Positive correlationNegative correlation

A positive correlation is such that as x increases, y also increases.

However, a negative correlation is such that as x increases, y decreases.

Hence, we can conclude that the x and y values of a scatter plot with negative correlation are in opposite direction.

See attachment for a scatter plot with negative correlation.
