[tex]\frac{4^{2}-6 }{(3*4)+10} =\frac{16-6}{12+10} =\frac{10}{22} =\frac{5}{11}[/tex]
if the average of 6 numbers is 60, what is their sum?
Answer:
10
Step-by-step explanation:
The average of a dataset is the mean value of the dataset. It is calculated by dividing the sum of the dataset by the number of items in the dataset. The sum of the 6 numbers is 360.
Given that:
[tex]Average = 60[/tex]
[tex]n = 6[/tex] --- the number of data in the dataset
The average of a dataset is represented as:
[tex]Average = \frac{Sum}{n}[/tex]
Make Sum the subject
[tex]Sum = Average * n[/tex]
This gives:
[tex]Sum = 60 * 6[/tex]
[tex]Sum = 360[/tex]
Hence, the sum of the 6 numbers is 360.

Step-by-step explanation:
The circumference of the wheel is given by ...
C = πd
C = π(20 cm) ≈ 62.83185 cm
100 turns of the wheel will be a distance 100 times this value, or ...
race = 100C = 100(62.83185 cm) = 6283.185 cm
Chubby ran about 6283 cm.

To get the required 4 significant figures in the answer, we used the "pi button" on the calculator. Alternatively, you could use the ratio π ≈ 355/113, which is good for 6 significant figures.

A: 4/7

C:5/7
D: 2/7
D: 2/7
Step-by-step explanation:
The probability of an event x is how likely the event will occur. It is given as;
P(x) = number of expected outcomes / number of possible outcomes
Given:
Event A = The place is a city.
Therefore,
P(A) is the probability that the event A happens. i.e the probability that a place is a city.
P([tex]A^c[/tex]) is the probability that the event A does not happen. i.e the probability that a place is not a city
Also,
The sum of the probability that an event happens and the probability that the event does not happen is equal to 1. i.e
P(A) + P([tex]A^c[/tex]) = 1
From the table,
P([tex]A^c[/tex]) is found by counting the number of places that does not have a tick on the "is a city" column, then divide the result by the total number of places. i.e
P([tex]A^c[/tex]) = 2 ÷ 7
P([tex]A^c[/tex]) = 2/7
Therefore P([tex]A^c[/tex]) which is the probability that the place is not a city is 2/7

can someone please help me solve?
Answer:
0.75
Step-by-step explanation:
d = FE = 4
e = DF = 3
f = ED = 5
f/sin(F) = e/sin(E)
5/sin(90) = 3/sin(E)
5 = 3/sin(E)
sin(E) = 3/5 =0.6
E = asin(0.6) = 36.869898... degrees
tan(E) = tan(36.869898...) = 0.75

Is segment ST tangent to circle P1
Answer:
B . Yes
Step-by-step explanation:
Recall: a tangent of a circle is perpendicular to the radius of a circle, forming a right angle at the point of tangency.
Therefore, if segment ST is tangent to circle P, it means that m<T = 90°, and ∆PST is a right triangle.
To know if ∆PST is a right triangle, the side lengths should satisfy the Pythagorean triple rule, which is:
c² = a² + b², where,
c = longest side (hypotenuse) = 37
a = 12
b = 35
Plug in the value
37² = 12² + 35²
1,369 = 1,369 (true)
Therefore we can conclude that ∆PST is a right triangle, this implies that m<T = 90°.
Thus, segment ST is a tangent to circle P.

Find cot 0, sec 0, and cos 0, where is the angle shown in the figure. Give exact values, not decimals approximations.
Answer:
Cot 0 = undefined
Sec0 = cos0 = 1
Step-by-step explanation:
According to trig identity
Cot theta = 1/sin theta
Sec theta = 1/cos theta
Hence
Cot 0 = 1/tan0
Cot 0 = 1/0
Since a/0 is undefined, hence cot 0 will be undefined
Sec 0 = 1/cos 0
Sec0 = 1/1 = 1
Cos 0 = 1
Use the order of operations to simplify the expression

A union of restaurant and foodservice workers would like to estimate the mean hourly wage, , of foodservice workers in the U.S. The union will choose a random sample of wages and then estimate using the mean of the sample. What is the minimum sample size needed in order for the union to be confident that its estimate is within of
Answer: the minimum sample size needed = 145
Step-by-step explanation:
Formula for sample size:
[tex]Sample \ size =(\dfrac{z^*\times standard\ deviation}{margin \ of \ error})^2[/tex]
, where z* = Critical z-value
Given: Standard deviation = 2.15
Margin of error = 0.35
Z* for 95% confidence = 1.96
Sample size = [tex](\frac{1.96\times2.15}{0.35})^2[/tex]
[tex]=(12.04)^2\\\\=144.9616\approx145[/tex]
Hence, the minimum sample size needed = 145

Answer:
h=0
Step-by-step explanation:
if you plug it it works
Answer:
The input is an identity, it is true for all values.
Step-by-step explanation:
17 + 4h + 2 = 19 - 5h + 9h
19 + 4h = 19 - 5h + 9h
19 + 4h = 19 + 4h
19 - 19 + 4h = 19 - 19 + 4h
4h = 4h
4h ÷ 4 = 4h ÷ 4
h = h
The input is an identity, it is true for all values.

Answer:
C. C = 3P
Step-by-step explanation:
C = total costs
P = number of popsicles
Unit price of 1 popsicle = $3
To get the total cost of popsicles, we need to multiply the number of popsicles bought by the price of each popsicles
Total cost of popsicles = number of popsicles × unit price
Thus, the question would be written as:
C = 3P

Answer:
d. Cell phone usage rose by 8%.
Explanation:
71 - 63 = 8
The statement that is true about percentage increase in cell phone use among teenagers is; c. Cell phone usage rose by 12.7%.
How to calculate percentage increase?We are given;
Percentage of teenagers using cell phone in 2006 = 63%
Percentage of teenagers using cell phone in 2008 = 71%
Thus;
Percentage increase = (71% - 63%)/63%
Percentage increase = 12.7%
