Answer:
Downloading 28 songs will cost $26.64.
Step-by-step explanation:
Given that a brand-new music service is offering specials on individual song downloads, and the cost is $ 0.74 for each song up to 20 songs per month, and the cost doubles to $ 1.48 per download for any number of downloads over 20, to determine how much would it cost to download 28 songs the following calculation should be performed:
(20 x 0.74) + (8 x 1.48) = X
14.8 + 11.84 = X
26.64 = X
Therefore, downloading 28 songs will cost $ 26.64.

Through extensive data collection, quality control experts have verified that the true mean weight of a wrapped Starburst candy is 5.1 grams, as advertised on the package. However, in a class activity where you selected and weighed 8 wrapped Starburst candies you obtained a p-value of 0.003 and concluded that the true mean weight of Starburst candies is not as advertised. What type of error was potentially made in this hypothesis test
Answer:
Type 1 error.
Step-by-step explanation:
H0 : μ = 5.1
H1 : μ ≠ 5.1
The Pvalue of the test = 0.003
Decision made by the researcher was conclude that mean weight is not as advertised, that is the researcher rejected the Null hypothesis.
However, when the Pvalue is < α - value , we reject the null ; The type of error the researcher could have made is that ; The mean weight may be truly as advertised, Hence, leading us to make a false positive error, thus is rejecting a true null. This is a TYPE 1 error.
Za and Zb are
complementary angles. Za measures 59º.
What is the measure of Zb?
Answer:
Zb = 31
Step-by-step explanation:
Complementary angles mean that the angles add up to 90 so:
Za + Zb = 90
59 + Zb = 90
Zb = 90 - 59
Zb = 31

G and H are mutually exclusive events. • P(G) = 0.5 • P(H) = 0.2
Answer:
[tex]P(G\ or\ H) = 0.7[/tex]
Step-by-step explanation:
Given
[tex]P(G) = 0.5[/tex]
[tex]P(H) = 0.2[/tex]
Required [Missing from the question]
[tex]P(G\ or\ H)[/tex]
Because the events are mutually exclusive, we use:
[tex]P(G\ or\ H) = P(G) + P(H)[/tex]
So, we have:
[tex]P(G\ or\ H) = 0.5 + 0.2[/tex]
[tex]P(G\ or\ H) = 0.7[/tex]
In the diagram, KLMN is a rectangle, and the two shaded regions are squares. If the length of KL is 6 centimeters, and the length of KN is 14 centimeters, which is closest to the length of ST in centimeters?
Answer:
15.2cm
Step-by-step explanation:
From the given diagram;
KN = SN = 14cm
KL = NT = 6cm
Required
ST
Using the Pythagoras theorem;
ST² = SN² + NT²
ST² = 14² + 6²
ST² = 196 + 36
ST² = 232
ST = √232
ST = 15.2cm
Hence the length of ST is 15.2cm

Move a word and a value to complete the sentence . The best center of measure for this data is the which is equal toseconds mean median 10.88 10.9010,8 11.1
Answer:
If you help me ill help you
Step-by-step explanation:
Carmen's father is 28 years older than her, 3 years ago we was 5 times her age, what are their ages?
The best centre of measure for this data is the mean which is equal to 10.90 seconds.
Mean, median and mode are use to measure for central tendency. Therefore, let's arrange the values in ascending order.
10.72, 10.75, 10.78, 10.80, 10.80, 10.88, 10.96, 10.99, 11.02, 11.10, 11.10,
According to the data, the values are very close to catch. Therefore, the mean will be used. Therefore,
mean = sum of data / number of data
mean = 10.72 + 10.75 + 10.78 + 10.80 + 10.80 + 10.88 + 10.96 + 10.99, 11.02 + 11.10 + 11.10 / 11
mean = 119.9 / 11
mean = 10.90

$987.65 is invested at 0.4% annual interest for 5 years.
a. Simple Interest b. Compound Interest
Answer:
I. Simple interest = $19.753
II. Compound interest = $1007.6
Step-by-step explanation:
Given the following data;
Principal = $987.65
Interest rate, R = 0.4%
Time, T = 5 years
To find the simple interest;
S.I = PRT/100
S.I = (987.65*0.4*5)/100
S.I = 1975.3/100
S.I = $19.753
II. To find the compound interest;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Substituting into the formula, we have;
[tex] A = 987.65(1 + \frac{0.4}{100})^{5}[/tex]
[tex] A = 987.65(1 + 0.004)^{5} [/tex]
[tex] A = 987.65(1.004)^{5} [/tex]
[tex] A = 987.65(1.0202)[/tex]
A = $1007.6

Answer:
As it says he is incorrect.
Step-by-step explanation:
To start, if you were to multiply something such as 5*1, then you would get the same number. Another example would be 8*0. Anything multiplied by 0 IS zero. He does give some valid answers, but there are also ones with smaller numbers. That is why Jackson is incorrect.
