Answer:

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

Step-by-step explanation:

Given that :

Number of red balls = 4

Number of Blue balls = 3

Total number of balls = (4 + 3) = 7

Picking without replacement :

Number of picks = 2

1st pick is red :

Probability = (required outcome / Total possible outcomes)

USing combination formula :

nCr = n! / (n-r)! r!

Total possible outcome :

7C2 = 7! / 5!2! = 7*6 / 2 = 42 / 2 = 21

X = number of red

For red = 0;

P(x =0) = required outcome / Total possible outcomes

P(x = 0)

Required outcome : [4C0 * 3C2)]

P(x = 0) = [(4C0 * 3C2)] / 21 = (1*3)/21 = 3/21 = 1/7

P(x = 1)

Required outcome : [4C1 * 3C1)]

P(x = 1) = [(4C1 * 3C1)] / 21 = (4*3)/21 = 12/21 = 4/7

P(x = 2)

Required outcome : [4C2 * 3C0)]

P(x = 2) = [(4C2 * 3C0)] / 21 = (6*1)/21 = 6/21 = 2/7

Hence ;

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

Answer: The tourist was in the taxi for 23 miles.

Step-by-step explanation:

Step-by-step explanation:

speed =4 miles/hour

distance travelled =31 miles

we have

speed =distance/time

time =31/4hour

for taxi

time =2hours

speed =50mph

distance covered by taxi =?

we have

speed =distance /time

50=distance/2

distance =50×2=100miles

Michael drove 1125 miles and paid $295 for renting the truck for 3 days

Rental company charges per day = $70

Rental company charges per mile = $0.20

Number of days truck is rented by Michael = 3 days

The total amount paid by Michael for the truck = $295

Let x be the number of miles Michael drives the truck

Formulating the equation using the information given in the question:

295 = 70 + 0.20(x)

295-70 = 0.20(x)

225 = 0.20(x)

x = 1125 miles

Therefore, the total miles driven by Michael is 1125 miles.

Michael paid $295 for driving the truck for 1125 miles and renting it for 3 days.

The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.

We are provided with the equation V = 5000[tex]e^{0.05t}[/tex]

The equation can be simplified as

V = 5000 e0* (0.05t)

V= 250t

This linear equation can be plotted for different values of t which are

If t=0, V = 0

If t=1, V = 250

If t=2, V = 500

If t=3, V = 750

If t=4, V = 1000

If t=5, V = 1250

If t=6, V = 1500

If t=7, V = 1750

If t=8, V = 2000

If t=9, V = 2250

If t=10, V = 2500

If t=11, V = 2750

If t=12, V = 3000

If t=13, V = 3250

If t=14, V = 3500

If t=15, V = 3750

If t=16, V = 4000

If t=17, V = 4250

If t=18, V = 4500

If t=19, V = 4750

If t=20, V =5000

Now, we just have plot these 20 coordinates

The graph of equation V = 5000[tex]e^{0.05t}[/tex] is upward sloping straight line.

A linear equation is an equation with the maximum degree of one. This means that in a linear equation, no variable has an exponent greater than 1. A linear equation's graph is always a straight line.

Answer:

a. (92.4, 94.8)

Step-by-step explanation:

Given that:

Mean (m) = 93.6

Standard deviation (σ) = 4.2

Sample size (n) = 34

α = 90%

Confidence interval around sample mean :

Mean ± Zstatistic * s/√n

Z0.90 = 1.645 (Z probability calculator)

s / √n = 4.2 / √34 = 0.7202940

Lower limit = 93.6 - (1.645 * 0.7202940) = 92.41511637 = 92.4

Upper limit = 93.6 + (1.645 * 0.7202940) = 94.78488363 = 94.8

Out of the following types of angles adjacent angles do not have equal measure.

Here, from the given figure, we can see that the 2 horizontal lines are parallel to each other and a transversal is drawn between them.

When 2 lines are parallel and joined by a transversal, any two pairs or alternate exterior angles, alternate interior angles and corresponding angles will be equal.

However, any to pairs of adjacent angle will not be equal. The sum of a pair of adjacent angles that lie on the straight line is 180°.

Here, one pair of adjacent angles is ∠1 and ∠2. Thus-

∠1 + ∠2 = 180

∠1 and ∠2 will be equal only when both of them are 90° each. Here, we are not given that they are 90.

Let x be the rate per square foot

✔️Company A charges: $215 + $0.50x

If they are installing 400 ft² of carpet, they would be charged the following by company A,

Substitute x = 400 into the equation.

We have:

$215 + $0.50(400) = $415

They would pay $415 if they use Company A's services

✔️Company B charges: $100 + $0.75x

If they are installing 400 ft² of carpet, they would be charged the following by company B,

Substitute x = 400 into the equation.

We have:

$100 + $0.75(400) = $400

They would pay $400 if they use Company B's services .

✅Company B would be a better choice because the total charges they would pay to install 400 ft² carpet is cheaper than they would pay for Company A.

Substitute to get:

7x+14=8.4x

subtract 7x from both sides

14=1.4x

Answer:

5 + 1(22-10)

Step-by-step explanation:

3 × 22 = 66

5 + 1(22-10) =5(12) = 60

6 × 7 + 8 × 3 = 42 + 24 = 66

1084 - 1018 = 66

(6 + 5)6 = (11)6 = 66

Answer:

5 + 1(22-10)

Step-by-step explanation:

First we need to solve for 11(7-1). Since the 7 - 1 is in the parenthesis it is what you do first. We know 7 - 1 equals 6. Since we got 6 as our answer for 7 - 1 we would take the 6 and multiply it with the 11 in the equation 11(7-1). If we would multiply 6 x 11 we would have an answer of 66.

Now we need solve each equation to see which one doesn't equal 66.

3 x 22 = 66 therefore it wouldn't be our answer.

5 + 1(22-10), we should always remember that we solve the equation with the parenthesis first. So if we would solve 22 - 10 we would get 12. Next we need to solve 5 + 1 and we should know this equals to 6. Now since we have our answer to both equation we would need to add 12 + 5 If we added those two number we'd get 17. There this would be our ANSWER.

6 x 7 + 8 x 3, we'll need to multiply 6 x 7 and then 8 x 3 after we get our answers to those equations we would need to add them and see if we would get 66 or not. So first I would multiply 6 x 7 and when I multiplied it I got 42. Next we would multiply 8 x 3 and that would equal 24. Now we need to ad 42 + 24. When we add 42 + 24 we get the answer of 66. Therefore this wouldn't be our answer.

1084 - 1018, this one would be easy to solve so we would nee to solve 1,084 - 1,018. If you don't know how to solve that it's okay! We can do it together. So if you write it in a paper or on something you could write it like I'll use a board. You would need to have 1,084 written in the top because that's the biggest number and 1,018 in the bottom because that a smaller number then 1,084. So we would nee to solve the one's place first. We wouldn't be able to solve 4 - 8 so we need to go over to the tens place and take from there now since we took from the 8 it'd become 7 and now the 4 is 14. So we'd do 14 - 8 for the ones place and we have our answer as 6. Now we need to solve the tens place 7 - 1  we know that equals 6 so we need to put 6 under our tens place. Next we go to the hundred place and do 0 - 0 and that's really easy haha it'd equal 0. So under the hundred place we can put 0 or leave it blank I left mines blank. Now finally we would do 1 - 1 and we know that equals 0 as well. So we can put 0 under our thousand place or leave it blank, I left it blank. Therefore this equals 66 so this wouldn't be our answer. Below in the picture I showed my work. :)

(6+5)6, first we do what's in the parenthesis. Which is 6 + 5 that'd equal 11. So since now we have 11 as our answer for 6 + 5 we'd need to do 11 x 6 and that would equal 66. Therefore our answer for this equation would be 66 so it wouldn't be our answer..
