If Danny earned $1,000 on a 4 year investment at a rate of 6%, how much was his original investment?

Answer:

1. x = 4       2. x = 8     3. p = 30

Step-by-step explanation:

1.    x + 7 = 11          check:      (4) + 7 = 11

         - 7   - 7                                  11 = 11

        x  =  4

2.   x - 12 = -4         check:       (8) - 12 = -4

        + 12   + 12                                -4 = -4

      x = 8

3.  multiply p/5 by 5 it cancels each other out and then you do the same thing to the other side. multiply 6 by 5 and you get 30  

check:    (30)/5 = 6

                      6 = 6

             30 divided by 5 equals 6

Answer: c=4 d=5

Step-by-step explanation:

Answer:

a. 0.443

b. 0.023

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The weight of turkeys is normally distributed with a mean of 22 pounds and a standard deviation of 5 pounds.

This means that [tex]\mu = 22, \sigma = 5[/tex]

a. Find the probability that a randomly selected turkey weighs between 20 and 26 pounds.

This is the pvalue of Z when X = 26 subtracted by the pvalue of Z when X = 20. So

X = 26

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{26 - 22}{5}[/tex]

[tex]Z = 0.8[/tex]

[tex]Z = 0.8[/tex] has a pvalue of 0.788

X = 20

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{20 - 22}{5}[/tex]

[tex]Z = -0.4[/tex]

[tex]Z = -0.4[/tex] has a pvalue of 0.345

0.788 - 0.345 = 0.443

The answer is 0.443

b. Find the probability that a randomly selected turkey weighs below 12 pounds.

This is the pvalue of Z when X = 12. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{12 - 22}{5}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.023

The answer is 0.023.

Answer:

1860

Step-by-step explanation:

The triangles are reflections of each other and since YX=YZ we know that YZ=350

add 350+350+230=930

930×2=1860 - for both parks

Answer:

x= 9

y=-12.5

Step-by-step explanation:

3x+2y = 2×2

2x+2y =-7×3

6x+4y =4

- 6×+6y =-21

-2y =25

y=-12,5

2x+2(-12,5)= -7

2x+-25= -7

2x= -7+25

2x/2=18/2

x= 9

Answer

I think A or c

Step-by-step explanation:

Your answer to this would be A, The table and equation of the same slope.

To find this, just divide Y by X. For ex, this could look something like 12 divided 4, 15 divided by 5, or 18 divided by 6.

To figure this out too, you can plug in the X and Y components into the equation to see if it checks out.

Answer:

243u⁵

Step-by-step explanation:

you need to put it in brackets then expand

(3u)⁵ = 243u⁵

Answer:

243u^5.

Step-by-step explanation:

Triple u = 3u.

Taking to power 5

= (3u)^5

= 243u^5.

Hi there!

absolute value= the opposite of that number if only negative:

Step By Step Explanation:

        41-1=40

bring a negative sign if not absolute value.

        1+51=52

since it’s already in it’s abolute value it won’t change..

        61-1=60

bring a negative sign if nessary..

Therefore, the absolute value for the expression 1-41, 1 +51, 1-61 is 40,52, and 60..

Answer:

5 buses

Step-by-step explanation:

Adults and students are both people, add them all up (41+19) and you get 60 People in total. If you divide that by 12 you get 5.

Hope that helps :)

Answer:

2 hours 10 minutes

Step-by-step explanation:

LA has a one hour time zone difference than Denver.  So if it was 9:55 am when you left LA, that is LA time.  So, in Denver it was 10:55 am.  If you land in Denver, Colorado at 1:05 pm it is the same as 12:05 pm in LA.  So you can just count the hours from 9:55 am to 12: 05 pm.

Answer: The fish can jump 5m high.

Step-by-step explanation:

Given that

s = 3h

where

h  = the height(cm) the fish jumps out of the water

and s = speed of the fish(meters per second)  then

3 must have seconds as its unit.

Now, If the fish is swimming at 15 meters per second

Then the fish can jump =

s= 3h

15m/s =3h

h= 15m/s/3s

h= 5 meters
