Is this expression equivalent to 1.5?

15.0 / 10
15.0 (divided by) 10

Answer:

$ 2,200

Step-by-step explanation:

If it cost $1,100 to make 500 then double that and you get $2,200

Answer:

$2100

Step-by-step explanation:

After 500 cards, there is a discount.  

(1100/500 = 2.2) So, $2.20 per card for the first 500 cards.

For every 150 cards after the initial 500, it costs $300, or $2.00 per card.  (300/150 = 2)

If you want 1,000 cards, you are ordering 500 of them at $2.20 per card and the second 500 cards at $2.00 per card.

(500x2.2) + (500x2)= 2100

Answer:

a) By the Central Limit Theorem, the mean is $142 and the standard deviation is $0.7488.

b) By the Central Limit Theorem, approximately normal.

c) 0.0901 = 9.01% probability that the average cable service paid by the sample of cable service customers will exceed $143

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use 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.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

The mean monthly fee is $142 and the standard deviation is $29.

This means that [tex]\mu = 142, \sigma = 29[/tex]

Part a: what are the mean an standard deviation of the sample distribution of x hat show your work and justify your reasoning.

Sample of 1500(larger than 30).

By the Central Limit Theorem

The mean is $142

The standard deviation is [tex]s = \frac{29}{\sqrt{1500}} = 0.7488[/tex]

Part b: what is the shape of the sampling distribution of x hat justify your answer.

By the Central Limit Theorem, approximately normal.

Part C: what is the probability that the average cable service paid by the sample of cable service customers will exceed $143?

This is 1 subtracted by the pvalue of Z when X = 143. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{143 - 142}{0.7488}[/tex]

[tex]Z = 1.34[/tex]

[tex]Z = 1.34[/tex] has a pvalue of 0.9099

1 - 0.9099 = 0.0901

0.0901 = 9.01% probability that the average cable service paid by the sample of cable service customers will exceed $143

Answer:

Jenns account has the greater simple interest rate.

Step-by-step explanation:

The formula for simple interest is:

A = P * ( 1 + r * t )

Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.

For Lindsey:

253 = 250 * ( 1 + r * t )

Solve for r

r = ( 253/250 ) - 1 = 0.012

Lindsey simple interest was 1.2% annually

For Jenn:

257.50 = 250 * ( 1 + r * 2 )

r = ( 257.50/250 ) - 1 )/2 = 0.015

Jenn simple interest was 1.5% annually  

Therefore Jenns account has the highest simple interest rate.

Answer:

Lindsay’s interest is $3 for one year. Using the formula for interest, I = prt, Lindsey’s money is earning at a rate of 1.2%. Jenn has earned $3.75 for one year. Her money is earning at a rate of 1.5%, which is a higher interest rate.

3) Reflexive Property

4) SAS

Step-by-step explanation:

1. The Reflexive Property states that: a quantity is congruent (equal) to itself.

1. SAS theorem states that: two triangles are equal if two sides and the angle between those two sides are equal.

2. Because it is given that RS ≅ UT and RT ≅ US, and it includes the same 2 lines being equal as given/said, RST ≅ UTS because of SAS (theorem).

Answer:

1080

Step-by-step explanation:

if  you are trying to find the volume the formula is

width x length x height

if you plug in 6x15x12 you get 1080 so the volume of the figure is 1080

Answer:

Angle R is congruent to angle Y; line ZX is congruent to line SQ

Step-by-step explanation:

Order matters when listing sides and angles, as in the question.

R is second listed angle, and so is Y.

Line ZX is first and third listed, so congruent side is line SQ

Answer: 125

The best prediction for the number of times a 4 will be drawn from the pile is:

A set of cards contains cards numbered 1 – 8.

So, the theoretical probability that 4 comes up is:

Ratio of Number of favorable outcome( outcome of 4) to the total umber outcome(i.e. 8 )

Hence, Theoretical Probability that 4 is drawn=1/8

Now, out of 1000 trials the best prediction of number of times 4 is drawn is:

(The probability of drawing 4)×(Number of experiments or trials)

=(1/8)×1000

=125

Complete Question:

A number decreased by eight is five.

Group of answer choices.

A. C + 8 = 5

C. -8c = 5

B. C - 8 = 5

D. S = 5

Answer:

B. C - 8 = 5

Step-by-step explanation:

Let the unknown number be C.

Translating the word problem into an algebraic equation, we have:

C - 8 = 5

Simplifying further, we find that;

C = 5 + 8

C = 13

Therefore, the unknown number is 13.

Answer:

a. V = 3M

b. T = 5S

c. Y = 17x

d. H = 12M

e. P = 0.5N

Step-by-step explanation:

a. V= 12 when M =4

12/4 = 3, so in this case, V is 3 times M, that is, V = 3M

b. T= 5 when S=1

5/1 = 5, so in this case, T is 5 times S, that is, T = 5S

c. Y= 34 when x=2

34/2 = 17, so in this case, Y is 17 times x, that is, Y = 17x

d. H=48 when M=4

48/4 = 12, so in this case, H is 12 times M, that is, H = 12M

e. P= 5 when N=10

5/10 = 1/2 = 0.5, so in this case, P is half of N, that is, P = 0.5N
