Answer:
So, I cannot answer the whole question, but I can give you my thought process. SO, since you need to feed 40 people with a quarter of each meal - you would need 10 pounds of each dish. Therefore the information about the "least amount" of each dish is met. As mentioned, x = pounds of pasta salad, while y = pounds of fruit salad. this means x would equal 10 and y would equal 10. In order to find out what it would cost is:
2.50 x 10 = 25 ($25)
3.75 x 10 = 37.5 ($37.50)
the function could possibly be f=10+10?
The maximum amount of food you should buy would be 20 pounds of food, considering you need to have enough for each guest.
You should buy 10 pounds or $25 worth of pasta salad, and 10 pounds, or $37.50 worth of fruit salad.

Step-by-step explanation:
quadratic graphs
y=x squared - 4x
This is one way of doing it.
We want to get the function into vertex form.
y = x2 - 4x + 2 Subtract 2 from both sides.
y - 2 = x2 - 4x Add (-4/2)2 , or 4, to both sides.
y - 2 + 4 = x2 - 4x + 4 Now that the right hand side is a perfect square trinomial, factor it.
y + 2 = (x - 2)(x - 2)
y + 2 = (x - 2)2 Subtract 2 from both sides.
y = (x - 2)2 - 2
When the equation is in this form, we can see that this is the graph of y = x2 shifted to the right 2 units and shifted down 2 units. The vertex is at (2, -2). So plot the first point at (2, -2) and go up just like a basic parabola from there. :)

It is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Answer:
27 /125
is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 27 and 125 is 1
Divide both the numerator and denominator by the GCD
27 ÷ 1 /125 ÷ 1
Reduced fraction:
27 /125
Therefore, 27/125 simplified to lowest terms is 27/125.

Answer:
A) ∠5 = 160°
B) ∠4 = 37°
C) ∠3 = 98°
Step-by-step explanation:
A)
If ∠1 = 160°
⇒ ∠5 = ∠1 = 160° (∵ Corresponding angles are always equal)
B)
If ∠6 = 37°
⇒ ∠4 = ∠6 = 37° (∵ Vertical angles are always equal)
C)
If ∠8 = 82°
⇒ ∠8 = ∠6 = 82° (∵ Alternate interior angles are always equal)
Now ,
∠6 + ∠3 = 180° (∵ Linear pair)
⇒ ∠3 + 82° = 180°
⇒ ∠3 = 180° - 82° = 98°

Answer:
1) 2 and 4
2) 3 and 4
3) 7 and 8
4) 9 and 10
5) 21 and 22
Step-by-step explanation:
#1
Since √(8) = √(2×4) = 2√2
then the √(8) lies between 2 & 3
#2
Since √(9) = 3 & √(16)= 4
then √(14) lies between 3 & 4
#3
√(60) = √(4×15) = 2√(15)
since √16 = 4 and 4 × 2 = 8
then 2√(15) < 8
∴ the √16 lies between 7 & 8
#4
√99 = √(9×11) = 3√11
√11 lies between √9 & √16 but closer to √9
& 3 × √16 = 12
the 3√11 = √99 likely lies between 9 & 10
#5
√444 = √(4×111)= 2√111
since √100 = 10 & √121 = 11
& 2×10= 20 & 2×11= 22
then 2√111 is likely between 21 & 22

A production process produces electronic component parts. It is presumed that the probability of a defective part is 0.01. During a test of this presumption, 500 parts are sampled randomly and 15 defectives are observed. (a) What is your response to the presumption that the process is 1% defective
Testing the hypothesis, we have that since the p-value of the test is 0 < 1, our response is that the presumption underestimates the proportion of defective parts.
At the null hypothesis, we test if the proportion of defectives is of at most 1%, that is:
[tex]H_0: p \leq 0.01[/tex]
At the alternative hypothesis, we test if the proportion of defectives is of more than 1%, that is:
[tex]H_1: p > 0.01[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
From the sample, we have that:
[tex]n = 500, \overline{p} = \frac{15}{500} = 0.03[/tex]
Thus, the value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.03 - 0.01}{\sqrt{\frac{0.01(0.99)}{500}}}[/tex]
[tex]z = 4.49[/tex]
The p-value of the test is the probability of finding a sample proportion above 3%, which is 1 subtracted by the p-value of z = 4.49.
z = 4.49 has a p-value of 1.
1 - 1 = 0.
The p-value of the test is 0 < 1, which means that our response is that the presumption underestimates the proportion of defective parts.

Transpose for y.
y/5+ f = 3q
Answer:
y = 15q - 5f
Step-by-step explanation:
[tex]\frac{y}{5}[/tex] + f = 3q ( subtract f from both sides )
[tex]\frac{y}{5}[/tex] = 3q - f ( multiply through by 5 to clear the fraction )
y = 15q - 5f
If f(x) = 5-2x find f(9)+ 3
f (9) = 5 - 2 (9)
f (9) = 5 - 18
f (9) = - 13
f (9) + 3 = - 13 + 3
f (9) + 3 = - 10

q(8) = 39.
Answer:

Step-by-step explanation:
To solve this question, you need to plug in (substitute) 8 instead of x:
q(8) = [1/2(8)²] + 7
