Tell whether the relation is a function. Explain.
Answer:
It is not a function.
Step-by-step explanation:
A relation can only be a function if every input (x-value) of the set of values of the relation, has exactly one output (y-value).
In the relation given, one input, -2, has two output related to it, 5 and 0. That's (-2, 5) and (-2, 0).
Therefore, the relation is not a function.

in a cookie recipe 1 and 2/3 cups milk makes 16 cookies. How many cups of needed to make 24 cookies
Answer:
2 1/2 or 5/2 cups of milk
Step-by-step explanation:
if 16 cookies are made from 1 2/3 cups of milk which equals 5/3 cups of milk that means that you need 5/2 or 2 1/2 cups of milk to make 24 cookies because you need to multiply 5/3 by 16 and then multiply 5/48 by 24 which is 5/2 or 2 1/2 cups of milk
hector wants to send a parcel to spain
Answer:
The correct answer is £72 by WeGoFast and £80 by ParcelsFly
Step-by-step explanation:
Hector wants to send a parcel to Spain.
Dimension of his cuboid parcel is 10 cm by 10 cm by 40 cm.
Sum of the three dimension in cm = (10 + 10 + 40) cm = 60 cm.
Volume of the parcel in = (10 × 10 × 40) = 4000.
Price charge by WeGoFast = Sum of the three dimensions in cm × £1.20
= £ (60 × 1.20) = £72.
Price charged by ParcelsFly = Volume measured in × £0.02
= £ (4000 × 0.02) = £80
What is the coefficient: 4 - 2y
The coefficient of the variable y for the given equation 4 - 2y is -2.
What is the coefficient?A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.
We have,
An equation 4 - 2y,
So,
In the above-given expression,
We have only one variable and one Constant term,
i.e.
Constant term = 4
And,
Variable term = -2y
So,
In the variable term,
The coefficient of y = -2
So,
The coefficient of y is -2.
Hence, we can say that the coefficient of the variable y in the given equation is -2.

The difference between teenage female and male depression rates estimated from two samples is 0.08. The estimated standard error of the sampling distribution is 0.04. what is the 95% confidence interval? Use the critical value z - 1.96.
Round all calculations to two decimal places. Put lower bound in the first box and upper bound in the second box.
Answer: (0.0016, 0.1584)
Step-by-step explanation:
Given that:
Mean (m) = 0.08
Standard Error = 0.04
Zcritical at 95% = 1.96
Using the relation :
Mean ± Zcritical * (standard error)
0.08 ± 1.96 * (0.04)
Lower boundary = 0.08 - (1.96 * 0.04)
Lower boundary = 0.08 - 0.0784 = 0.0016
Upper boundary = 0.08 + (1.96 * 0.04)
Upper boundary = 0.08 + 0.0784 = 0.1584
Confidence interval is Hence,
(0.0016, 0.1584)
The 95% confidence interval is given by (0.0016 , 0.1584) and this can be evaluated by using the mean and standard error relation.
Given :
The difference between teenage female and male depression rates estimated from the two samples is 0.08.The estimated standard error of the sampling distribution is 0.04.The critical value z = 1.96.95% confidence level.To determine the 95% confidence interval using the following relation:
[tex]\rm \mu \pm z_{critical}\times standard \;error[/tex]
[tex]0.08\pm 1.96\times 0.04[/tex]
So, the lower and upper boundary is (0.0016 , 0.1584).
Therefore, the 95% confidence interval is given by (0.0016 , 0.1584).

Step-by-step explanation:
which of the following graph represents the solution set for 5x+38 ≤ 4(2-5x)
Answer:
Option C
Step-by-step explanation:
Given inequality is,
5x + 38 ≤ 4(2 - 5x)
5x + 38 ≤ 8 - 20x [Distributive property]
5x + 20x + 38 ≤ 8 - 20x + 20x [By adding 20x on both the sides of the inequality]
25x + 38 ≤ 8
(25x + 38) - 38 ≤ 8 - 38 [By subtracting 38 on both the sides of the inequality]
25x ≤ -30
[tex]\frac{25x}{25}\leq -\frac{30}{25}[/tex] [Dividing by 25 on both the sides of the inequality]
x ≤ 1.2
Therefore, Option (C) will be the correct graph.

Given:
[tex](x+9)^2[/tex]
To find:
The given expression as a trinomial in standard form.
Solution:
We have,
[tex](x+9)^2[/tex]
Using the formula, [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+9)^2=x^2+2(x)(9)+(9)^2[/tex]
[tex](x+9)^2=x^2+18x+81[/tex]
Standard form a trinomial is [tex]ax^2+bx+c[/tex].
[tex]x^2+18x+81[/tex] is in the standard form.
Therefore, the required expression is [tex]x^2+18x+81[/tex].
The book store earned x dollars in profit. Last week, the total profit
increased by 5%. Which expression represents the book store's total
increase in profit?
Answer:
x + 0.05x
Step-by-step explanation:
Given
Earnings earned by the bookstore = x
percentage increase = 5%
Increment = 5% of x
Increment = 0.05x
book store's total increase in profit = Original earning + increment
book store's total increase in profit x + 0.05x
Hence the expression that represents the book store's total increase in profit is x + 0.05x
