16 ÷ ( 2/5 + 2/ 3 ).
Answer:
15
Step-by-step explanation:
16 % (2/5 + 2/3) = 16 % (6/15 + 10/15) = 16 % 16/15 = 16/1 x 15/16 = 240 % 16 = 15

Amil took $65.00 to go shopping and he bought two pairs of jeans for $27.00 each. How much change will he have ? Choose the expression that is a correct translation of the problem
Answer:
11.00
Step-by-step explanation:
1. Since he's trying to buy 2 pairs you can multiply 27.00 by 2 or you can just add 27.00+27.00 and will get 54.00
2. Subtract 65.00-54.00
3. and you'll get 11.00
When the population distribution is normal, the statistic median {|X1 − X tilde|, . . . , |Xn − X tilde|}/0.6745 can be used to estimate σ. This estimator is more resistant to the effects of outliers (observations far from the bulk of the data) than is the sample standard deviation. Compute both the corresponding point estimate and s for the data below. (Round your answers to three decimal places.)25.01, 25.87, 26.34, 26.51, 26.75, 27.24, 27.40, 27.63, 27.83, 27.90, 28.08, 28.13, 28.37, 28.58, 28.59, 28.96, 29.20, 29.22, 29.38, 30.88
Answer:
The corresponding point estimate is 0.882.
The sample standard deviation is 1.373.
Step-by-step explanation:
The data set is:
S = {25.01, 25.87, 26.34, 26.51, 26.75, 27.24, 27.40, 27.63, 27.83, 27.90, 28.08, 28.13, 28.37, 28.58, 28.59, 28.96, 29.20, 29.22, 29.38, 30.88}
Compute the mean as follows:
[tex]\bar X=\frac{1}{n}\sum X\\\\=\frac{1}{20}\times [25.01+25.87+...+30.88]\\\\=\frac{1}{20}\times 557.87\\\\=27.8935[/tex]
Subtract the mean from each value and take the modulus of those values.
The new data set is:
S₁ = {2.8835, 2.0235, 1.5535, 1.3835, 1.1435, 0.6535, 0.4935, 0.2635, 0.0635, 0.0065, 0.1865, 0.2365, 0.4765, 0.6865, 0.6965, 1.0665, 1.3065, 1.3265, 1.4865, 2.9865}
Arrange these values in ascending order as follows:
S₂ = {0.0065 , 0.0635 , 0.1865 , 0.2365 , 0.2635 , 0.4765 , 0.4935 , 0.6535 , 0.6865 , 0.6965 , 1.0665 , 1.1435 , 1.3065 , 1.3265 , 1.3835 , 1.4865 , 1.5535 , 2.0235 , 2.8835 , 2.9865}
There are 20 observations in the data set.
The median value for an even set of values is the mean of the middle two values.
In this case the median will be the mean of the 10th and 11th observations.
[tex]\text{Median}=\frac{10^{th}obs.+11^{th}obs.}{2}=\frac{0.6965+1.0665}{2}=0.8815\approx 0.882[/tex]
Thus, the corresponding point estimate is 0.882.
Compute the standard deviation as follows:
In set S₁ we computed the absolute mean deviations.
Now take the square of these values and divide by (n - 1) to compute the sample variance:
[tex]\sigma^{2}=\frac{1}{n-1}\sum (|X_{i}-\bar X|)^{2}[/tex]
[tex]=\frac{1}{20-1}\times [(2.8835)^{2}+(2.0235)^{2}+...+(2.9865)^{2}]\\\\=\frac{1}{19}\times 35.7953\\\\=1.88396[/tex]
Compute the sample standard deviation as follows:
[tex]\sigma=\sqrt{\sigma^{2}}=\sqrt{1.88396}=1.373[/tex]
Thus, the sample standard deviation is 1.373.

What is x?
Note: Figure not drawn to scale
In the circle above, point A is the center and the length of arc BC is 2/5 of the circumference of the circle.
What is the value of x?
Answer:
The value of x is 144°
Step-by-step explanation:
Let us revise some facts about the circle
The measure of the circle is 360°The length of the circle is 2πr (circumference)If the length of an arc is a/b of the circumference (its length = a/b ×2πr), then the measure of the arc is also a/b of its measure (its measure = a/b × 360°)The measure of any central angle equals the measure of its subtended arcIn the given question
∵ A is the center of the circle
∴ Angle x is a central angle subtended by arc BC
∴ The value of x = the measure of arc BC
∵ The length of the arc BC is 2/5 of the circumference of the circle
∴ The measure of arc BC is 2/5 of the measure of the circle
∵ The measure of the circle = 360°
∴ x = 2/5 × 360°
∴ x = 144°
The value of x is 144°

Which graph I-IV matches with a?
Answer:
III
Step-by-step explanation:
At t = 0, x = 1.
At t = 0.5, x = 2.
At t = 1, x = 1.
The curve is symmetrical.
The graph that fits is III. x starts at 1, increases 2, then decreases at the same rate back to 1.

Gillian’s Restaurant has an ice-cream counter where it sells two main products, ice cream and frozen yogurt, each in a variety of flavors. The restaurant makes one order for ice cream and yogurt each week, and the store has enough freezer space for 115 gallons total of both products. A gallon of frozen yogurt costs $0.75 and a gallon of ice cream costs $0.93, and the restaurant budgets $90 each week for these products. The manager estimates that each week the restaurant sells at least twice as much ice cream as frozen yogurt. Profit per gallon of ice cream is $4.15, and profit per gallon of yogurt is $3.60.

A case of single-serving bags of chips contains 8 boxes. Each box contains 10 bags of chips.
A case of chips cost $29.60. What is the unit price for a single bag of chips?
Answer:
each bag of chips are 0.37 cents
Step-by-step explanation:
1 case =29.60
29.60 divided by 8 (number of boxes in case)=3.70
3.70 divided by 10(number of chip bags in box)=0.37
Therefore each bag of chips = 0.37cents

It is given that:
Modeling events using random numbers is known:
As we know, a simulation recreates random occurrences by specifying event outcomes with relative frequencies that match the real-world relative frequencies we're aiming to simulate using random numbers.
It's called a simulation when you use random numbers to model an event.

Does anyone know how to do this? Im so confused.
================================================
Work Shown:
AB+BC+CD = AD .... segment addition postulate
BC+BC+CD = AD ... replace AB with BC (since AB = BC)
BC+BC+BC = AD ... replace CD with BC (since BC = BC)
3*BC = AD .... combine like terms
3*BC = 12 .... replace AD with 12
BC = 12/3 .... divide both sides by 3
BC = 4
For right triangle PBC, the legs are BP = 3 and BC = 4. We can use the Pythagorean Theorem to find that the hypotenuse is PC = 5
The steps are shown below
(BP)^2+(BC)^2 = (PC)^2
3^2+4^2 = (PC)^2
9+16 = (PC)^2
25 = (PC)^2
(PC)^2 = 25
PC = sqrt(25)
PC = 5

Step-by-step explanation:
To get the answer for this, we're going to make an algebra equation and add every angle to make 360 in total. First, we can just write the equation.
x+(x-35)+(x-46)+1/2x=360
Next, we can simplify this.
3 1/2x-81=360
3.5x-81=360
Add 81 to both sides.
3.5x-81=360
+81 +81
3.5x=441
Divide by 3.5 on both sides.
3.5x=441
/3.5 /3.5

Each x is 126.
