Answer:

the computer was 280, and the printer was 6 times that. do the math an you have ur answer

The cost of a printer is $240 and the cost of a computer is $1440.

Given that, the cost of both computer and printer is $1680.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the cost of printer be x.

Richard paid six times as much for his computer as he did for his printer.

Then, the cost of computer will be 6x

Now, 6x+x=1680

⇒ 7x=1680

⇒ x=1680/7

⇒ x=$240

So, 6x=$1440

Therefore, the cost of a printer is $240 and the cost of a computer is $1440.

Answer:

The volume of the sphere is 179.50 cubic inches.

Step-by-step explanation:

To determine what is the volume to the nearest 10th of a sphere that has a radius of 3.5 inches, on cubic inches, the following calculation must be performed, knowing that the volume of a sphere arises from the formula 4/3 πr³ = V:

4/3 x 3.14 x 3.5³ = V

1.333 x 3.14 x 42.875 = V

1.333 x 134.6275 = V

179.50 = V

Therefore, the volume of the sphere is 179.50 cubic inches.

Explanation

Given that Sn = Sn-2 . (Sn-1 - 1)

Tn = Sn - Sn-1

Tn = Sn-2 . (Sn-1 - 1) - (Sn-3 . (Sn-2 - 1))

T3 = S1.(S2-1) - (S0.(S1-1)

T3 = 2.(3-1) - 1.(2-1)

T3 = 2(2) - 1(1)

T3 = 4-2

T3 = 3

T4 = S2.(S3-1) - (S1.(S2-1)

T4 =3.(-1) - 1.(2-1)

T4 = 2(2) - 1(1)

T4 = 4-2

T4 = 3

Answer:

solution given;

let

AB=a

AC=b=30ft

AB=c=20ft

<A=115°

By using Cosine rule.

a²=b²+c²-2bc cos angle

a²=30²+20²-2*30*20 Cos 115°

a²=1807.1419

a=√[1807.1419]

a=42.51

Side A is 42.51ft.

Again

Cos B=[tex] \frac{a²+c²-b²}{2ac} [/tex]

Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]

Cos B=0.7687

  C.  Slope-intercept

Step-by-step explanation:

There are numerous forms of the equation of a line. Here are a few.

  y = mx + b . . . . slope-intercept form; slope m, y-intercept b

  y -k = m(x -h) . . . . point-slope form; point (h, k), slope m

  ax +by = c . . . . standard form; mutually prime integers, a > 0

  x/a +y/b = 1 . . . . intercept form; x-intercept a, y-intercept b

  ax +by +c = 0 . . . . general form

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . two-point form; points (x1, y1), (x2, y2)

  (y2 -y1)/(x2 -x1) = (y -y1)/(x -x1) . . . . you might call this rise-run form

Answer: A

Step-by-step explanation:

The correct hypothesis is Option A.

A hypothesis is a supposition or suggested explanation for a phenomenon or issue. It is a preliminary claim that has to be examined and confirmed by logic, experimentation, or other means. A hypothesis can be used to steer the development of a theory or to make predictions about events that will happen in the future.

The appropriate set of hypotheses for this significance test is:

μ = 500 mL (null hypothesis) - The mean amount of liquid in each bottle in the batch is equal to the target value of 500 mL.

μ ≠ 500 mL (alternative hypothesis) - The mean amount of liquid in each bottle in the batch differs from the target value of 500 mL.

This is done in order to determine whether there is proof that the average volume of the bottles in this batch differs from the desired value of 500 mL.

The alternative hypothesis suggests that the mean quantity is different from the null hypothesis assumption that it is equal to 500 mL. The test will evaluate whether there is enough support for the alternative hypothesis to be accepted instead of the null hypothesis.

Answer:

A customer who sends 78 messages per day would be at 99.38th percentile.

Step-by-step explanation:

Normal Probability Distribution:

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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Average of 48 texts per day with a standard deviation of 12.

This means that [tex]\mu = 48, \sigma = 12[/tex]

a. A customer who sends 78 messages per day would correspond to what percentile?

The percentile is the p-value of Z when X = 78. So

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

[tex]Z = \frac{78 - 48}{12}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a p-value of 0.9938.

0.9938*100% = 99.38%.

A customer who sends 78 messages per day would be at 99.38th percentile.

x = 4

Step-by-step explanation:

If line A is parallel to line B, therefore,

9x + 4 = 5x + 20 (alternate interior angles theorem)

Solve for x. Collect like terms together

9x - 5x = -4 + 20

4x = 16

Divide both sides by 4

4x/4 = 16/4

x = 4

Therefore, the value of x that will make lime A parallel to line B is 4

Reduce 100 by 2 until 0 ; the reminder obtained is written from bottom to top.

2 | 100

2 | 50 r 0

2 | 25 r 0

2 | 12 r 1

2 | 6 r 0

2 | 3 r 0

2 | 1 r 1

Arranging from the bottom : 1100100 base 2

100 base 10 = 1100100 base 2

1010101 base 2 to base 10

1*2^6 + 0*2^5 + 1*2^4 + 0*2^3 + 1*2^2 + 0*2^1 + 1*2^0

64 + 0 + 16 + 0 + 4 + 0 + 1 = 85 base 10

1 mile = 5280 feets

Distance from earth to moon = 238900 miles

Distance in feets :

(5280 * 238900) = 1261392000 feets

Total distance from moon and back to earth = 2 * 1261392000 = 2522784000 feets

Using the relation :

Speed = distance / time

Speed = 1 feet per nano second

Distance = 2522784000 feets

1 = 2522784000 / time

Time = 2522784000 nano seconds

Converting to second :

2522784000 / 1000000000

= 2.522784 seconds
