INTL
DLL
Answer:
1.20, 10.8
Step-by-step explanation:
d = n^2 - 12n + 43
d = 30
30 = n^2 - 12n + 43
0 = n^2 - 12n + 13
now solve for n using quadratic formula:
a=1, b=-12, c=13
n = (-b +- sqrt( b^2 -4ac))/2a
two answers ( one for + the square root, one for - the square root)
n = 1.20, n = 10.8

Solve for the value of f: ½(6 + 4) + 5f = 10
Answer:
Start by combing any like variable and distributing the values.5+5f=10 5f=5f=12x+y=42
8x+7y=36
Using the process of eliminations.
Answer:
x=43,y=-44
Step-by-step explanation:
hey i hope it helps you
2x+y=42(7)
8x+7y=36(1)
14x+7y=294
8x+7y=36
6x=258
divide both sides by 6
x=43
to get y
2x+y=42
equate x=43
8(43)+7y=36
344+7y=36
344-36=7y
308=7y
divide both sides by 7
y=-44
As an estimation we are told €4 is $5. What is the conversion rate from € to $? Give your answer rounded to 2 DP.
Answer:
$1.25/€
Step-by-step explanation:
€4 = $5
Divide both sides by €4.
€4/€4 = $5/€4
1 = $5/€4 = $1.25/€
Since $1.25/€ is equal to one, multiplying a number of euros by it will not change the value of the number. It will convert it from euros to dollars.
Answer: $1.25/€

A soccer team sells three items for a fundraiser. The table shows the total sales for the items.
The team gets to keep $1 for every $10 in total sales.
Item Total Sales
Hats $196
T-shirts $504
Sweatshirts $420
Part A
If t is the total sales and k is the amount of money the team gets to keep,
which equations can be used to find the amount the team gets to keep?
Choose all that apply.
A. t ÷ 10 = k
B. k ÷ t = 10
C. 10 × t = k
D. t = 10 × (196 + 504 + 420)
E. 196 + 504 + 420 = t
Part B
How much money does the team get to keep? Enter your answer in the box.

Find the value of x
a)105°
b)85
c)75
d)25
Answer:
c) 75
Step-by-step explanation:
180-155 = 25
80+25+x=180
x = 75
Step-by-step explanation:
By Exterior Angle Theorem,
x = 155° - 80° = 75° (C).

The manufacturer of official NFL footballs uses a machine to inflate its new balls to a pressure of 13.5 pounds. When the machine is properly calibrated , the mean inflation pressure is 13.5 pounds, but uncontrollable factors cause the pressures of individual footballs to vary randomly from 13.3 to 13.7 pounds. For quality control purposes, the manufacturer wishes to estimate the mean inflation pressure to within 0.025 pound of its true value with a 99% confidence interval. What sample size should be used
Answer:
106
Step-by-step explanation:
Given that:
Mean (m) = 13.5 pounds
Error margin = 0.025
α = 99%
Variation interval = range = 13.3 to 13.7
Standard deviation (σ) estimate from range :
Range / 4
(13.7 - 13.3) /4
= 0.4 / 4
= 0.1
Zcritical at 99% = 2.576
Using the formula :
Sample size (n) = [ (Zcritical * σ) / M. E]^2
n = [(2.576 * 0.1) / 0.025]^2
n = (0.2576 / 0.025)
n = 10.304^2
n = 106.172
n = 107 samples
