Complete Question
A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is $2 per entree? ANY FOUR ENTREES FOR $20
Answer:
$7
Step-by-step explanation:
From the question we are told that :
Any 4 entrees = $20,
And there is a discount of $2 per entree.
Let us represent the original average cost of entrees as = a
Hence, we have the algebraic expression
4(a - 2) = 20
4a - 8 = 20
4a = 20 + 8
4a = 28
Divide both sides by 4
4a/4 = 28/4
a = 7
Therefore, the original average cost of the entrees if the discount is $2 per entree is $7.

Step-by-step explanation:
A sample of 300 guests at Universal Orlando theme parks in 2015 were selected and each was asked whether they were staying at one of the onsite Loews Hotels. In this sample, 63 guests, or 21%, indicated that they were staying in one of the onsite Loews Hotels. In this scenario, is 21% an example of a parameter or a statistic?
Answer:
Statistic
Step-by-step explanation:
a parameter describes a percentage of the whole population. For example. if the total population of guests were interviewed and 21% indicated they were staying at the hotel, it would have been a parameter
A statistic summarises data from a sample
The change will be a whole dollar amount, which can be negative, zero, or positive. Thus the change will be a(n
Answer:
Integer number
Step-by-step explanation:
A "whole dollar" amount means, there's no decimal point, or cents in the dollar amount.
This represents a whole number, which is an integer.
It is an integer because we are told that the while dollar amount could be negative, positive or zero.
A number that is zero, positive or negative, which is also not a fraction nor a decimal, meets the true definition of what can be referred to as an integer.
Thus, the whole dollar amount change could be 0, -4, 4.

Anglo Ameasures
Angle C is 31, Angle A is 30, and Angle B is 119.
Step-by-step explanation:
The measures of each of the angles in triangle ABC are
A = 18
B = 83
C = 79
Calculating the measure of anglesFrom the question, we are to determine the measure of each of the angles in triangle ABC
From the given information,
The measure of angle B is 29 more than three times the measure of angle A
That is,
B = 3A + 29 ------- (1)
Also, the measure of angle C is 61 more than the measure of angle A
That is,
C = 61 + A --------- (2)
We can also write that
A + B + C = 180 ----- (3) (Sum of angles in a triangles)
Put equations (1) and (2) into equation (3)
A + 3A + 29 + 61 + A = 180
5A + 90 = 180
5A = 180 - 90
5A = 90
A = 90/5
A = 18
Put the value of A into equation (1)
B = 3A + 29
B = 3(18) + 29
B = 54 + 29
B = 83
Put the value of A into equation (2)
C = 61 + A
C = 61 + 18
C = 79
Hence, the measures of each of the angles are
A = 18
B = 83
C = 79

How much will a person pay for 1.4 pounds of bananas at a price of $2.34 per pound
Answer:
$3.276
Step-by-step explanation:
From the question, we are told that the price of banana is
1 pound = $2.34
1.4 pounds = $ y
Cross Multiply
1 pounds × $y = 1.4 pounds × $2.34
$y = 1.4 pounds × $2.34/1 pounds
$y = $3.276
Therefore, a person will pay $3.276 for 1.4 pounds of banana
Traces of surface x2 + y2 − z2 = 1. Determine the equation for the family of traces in x = n.
Answer:
[tex]\mathbf{y^2 -z^2 =1- n^2}[/tex]
Step-by-step explanation:
Give that:
the surface equation is [tex]x^2 +y^2 -z^2 =1[/tex]
from the family of traces in x = n given that [tex]x^2 +y^2 -z^2 =1[/tex] , the equation can be represented as :
[tex]n^2 +y^2 -z^2 =1[/tex]
[tex]\mathbf{y^2 -z^2 =1- n^2}[/tex]
This represents a family of hyperbola for all values of n expects that n = ± 1
So, if n = ± 1,
Then
[tex]y^2 - z^2 = 0[/tex]
(y-z) (y+z) = 0
y = ± z
So, for n = ± 1, it is a pair of line for y = z, y = -z

6x-2 = 4x+48
Subtract 4x from each side
6x-4x-2 = 4x+48-4x
2x-2 = 48
Add 2 to each side
2x-2 +2 = 48+2
2x = 50
Divide by 2
2x/2 = 25
We want to find angle A
A = 6x-2
= 6*25 -2
150 -2
= 148
Answer:
Solution given:
<A=<B{alternate exterior angle are equal}
6x-2=4x+48
6x-4x=48+2
2x=50
x=50/2
x=25

Express the confidence interval 0.491 ± 0.057 in the form of p-E < p
A) 0434 B) 0.434 C) 0.491 D) 0.4625 < p <0.5195.Answer:
0.424<0.538
Step-by-step explanation:
Given the confidence interval 0.491 ± 0.057, we are to express in the form
p-E < p + E where E is the error
From the interval E = 0.057, p = 0.591
p±E = (p+E, p-E)
0.491 ± 0.057 = (0.491-0.057, 0.491+0.057)
0.491 ± 0.057 = (0.434, 0.548)
Hence the interval in the form
p-E < p + E is 0.424<0.538

Sam buys 3 different types of fruit in 3/4 pounds basket. Maria has 1 1/4 pound fruit. How many pounds of fruit do they have altogether?
Answer: 2 pounds
Step-by-step explanation: hope this helps:)
The amount of pounds of fruit Sam and Maria has altogether is 2 pounds of fruits.
How to find the weight in pounds?Sam buys 3 different types of fruit in 3/4 pounds basket,
Therefore, he has 3 / 4 pound weight of fruit.
Maria has 1 1/4 pound fruit. Therefore, the total weight Maria bought is 1 1 / 4 pounds.
1 1 / 4 = 5 / 4 pounds.
The total amount of fruit they have together is gotten by summing there weight in pounds.
Hence,
total weight = 3 / 4 + 5 / 4 = 3 + 5/ 4 = 8 / 4 = 2 pounds.
Therefore, the altogether they have 2 pounds of fruits.

The altitude of a helicopter increases 1000 feet every 4 minutes.
What is the unit rate of change (feet per minute) of the altitude?
Answer:
250 feet per minute
Step-by-step explanation:
1000 divided by 4 is 250. You divide them by each other because if you multiply 250 feet by 4 minutes, you get 1000.
The unit rate of change is 250ft/min
Rate of changeThis is change in distance with respect to time
Given the following parameters;
Distance covered = 1000feetTime taken = 4 minutesGet the unit rate of change as shown:
Unit rate = Distance/Time
Units rate = 1000/4
Unit rate = 250 ft/min
Hence the unit rate of change is 250ft/min
