For the following three questions, you will be testing for correlation between people's opinions of bilingual education (X) and their opinions about whether foreign born citizens should be allowed to run for president (Y) using the following data. The scale for both variables is 1 to 9, representing strong opposition to strong favor respectively. The null hypothesis is that X and Y are not correlated.
X Y

Calculate r. What are the degrees of freedom and do we retain or reject the hypothesis?
Answer:

Using a correlation Coefficient calculator, the correlation Coefficient, R value obtained is 0.7539
H0 : ρ = 0
H1 : ρ ≠ 0
The test statistic :
T* = r(√n - 2) / (√1 - r²)
T* = 0.7539 * √5 - 2) / (√1 - 0.7539²)
T* = 1.3057931 /0.6569891
T* = 1.988
Using the Pvalue from t statistic calculator :
T* = 1.988 ; df = 5 - 2 = 3
Pvalue = 0.0704
At α = 0.05
Pvalue > α ; we fail to reject H0 ; and thus conclude that and Y are not correlated. And conclude that X and Y are not correlated.

10.25 cm
C.
D.
20.09 m
20.9 m
9514 1404 393
Answer:
B. 9 cm
Step-by-step explanation:
The number of face masks Ray can make with 20 m of cord is ...
(20 m)(100 cm/m)/(10.25 cm/mask) = 195.12195 masks
To make one more mask, he will need to buy an additional amount of ...
(196 -195.12195)×(10.25 cm) ≈ 9.00 cm
Ray would need to add 9 cm of cord to his order.

height = [tex]\sqrt{equal side^2 - half base^2} = \sqrt{10^2 - 3^2} = \sqrt{100-9} = \sqrt{91}[/tex] = 9.54 cm
Emily has a coupon for 10%off of her purchase at the store. she finds a backpack that she likes on the discount rack. it’s original price is $60 but everything on the rack comes with the 30% discount. Emily says 10% and 40% make 50% so it will cost $30 is Emily correct explain what price will Emily pay for the backpack
Answer:
It is true that 20% and 30% make 50%. But in the context of sale prices it is essential to keep track of the wholes to which these percents apply. For the backpack, the 30% discount applies to the original $60 price: 30% of $60 is 0.3×60=18 making the discount on the backback $18. So after using the coupon, the backpack price becomes $42. Emily's additional 20% coupon applies not to the original backpack price but to the discounted price of $42: 20% of $42 is $8.40. Emily would need to save an additional $12 off the $42 price in order to buy the backpack for $30 so her calculations are not correct.
As seen in part (a), Emily's coupon lowers the discount rack price by $8.40 so she will pay
42−8.40=33.60
or $33.60.

Yesterday, the price of a can of beans at five supermarkets was $1.92, $2.01,
$1.89, $2.22, and $2.16, respectively, but today each supermarket raised its
price by $0.10. What is today's mean price of a can of beans at the five
supermarkets?
A. $2.24
B. $2.14
C. $2.04
D. $2.34
SUBMIT
Answer:
B. $2.14
Step-by-step explanation:
Given that
The price of the five supermarkets would be $1.92, $2.01,
$1.89, $2.22, and $2.16
And, each supermarket would be increased by $0.10
So, the today mean price would be
= ($1.92 + $2.01 + $1.89 + $2.22 + $2.16 + $0.10 × 5) ÷ (5)
= $10.7 ÷ 5
= $2.14

The sequence converges to ∞.
Answer:
[tex]The \ general \ term \ of \ the \ sequence = \frac{n + 1}{n}[/tex]
[tex]\lim_{n \to \infty} (\frac{n+1}{n}) = \lim_{n \to \infty} (\frac{1}{n} +1 ) = 1 + \lim_{n \to \infty} \frac{1}{n} = 1 + 0 = 1[/tex]

Use elimination to find the solution to the system of equations. 9x + 2y = 59
2x + 5y = 4 (Answers below)
Answer:
????????????????????
Answer:
Step-by-step explanation:
9x + 2y = 59 -> 9x = 59 - 2y -> x = (59-2y)/9
2x + 5y = 4 -> 2(59-2y)/9 + 5y = 4 -> (118 - 4y)/9 +5y = 4
118 - 4y + 45y = 4*9 -> 41y = -82 -> y = -2, thus x = 7

✎ Firstly , Remember these things :
To convert the percentage into a decimal fraction, remove the % symbol and divide it by 100 as in the case of conversion of percentage into fraction. We know that , divide by 100 means shifting to the left ; so to convert a percentage into decimal fraction, remove the % symbol and shift the decimal point two places to the left. For example : [tex]12\% = \frac{12}{100} = \boxed{ 0.12}[/tex][tex] \large{ \tt{☥ \: LET'S \: SOLVE}} : [/tex]
