Answer: 8(8u-5)
Step-by-step explanation:
Find a number that goes into both 64 and 40 the GCF of both is 8 so 8 goes on the outside of the new factor 8u-5 because if we distribute back we should arrive at the original equation
8(8u-5)
(no solutions)
Solve for x:
abs(x + 3) = -10
Hint: | Show the equation has no solution.
By definition, absolute value is positive. Therefore abs(x + 3) = -10 has no solution:
$14.5
Given data
Cost for the visit=442.25 Rubles
exchange rate
3 USD= 91.5 Rubles
but 1 USD= 91.5/3
= 30.5
Therefore if 1 USD is 30.5 Rubles
Then xUSD is 442.25 Rubles
cross multiply
30.5x= 442.25
divide both sides by 30.5
x= 442.25/30.5
x=14.5USD
The cost of the attraction is $14.5
Answer: a) 8%
b) 34%
c) 12%
<u>Step-by-step explanation:</u>
B
First to find the sample mean
Xbar= summation x/n= 40/4= 10
The sample standard deviation is:
S= √summation(x-xbar)²/ n-1
=√6/3= 1.4142
The degrees of freedom
df= N-1= 4-1= 3
For 95% confidence level, critical value of t
t= 3.182
The 95% confidence interval is:
=Xbar plus or minus t' *8/√n
= 10 plus or minus 3.182(1.4142/√4)
= 10plus or minus 2.25
So 7.75 or 12.25
