Answer:
a) 3 in²
Step-by-step explanation:
The area is given by the formula ...
A = 1/2bh
where b is the base length, and h is the height perpendicular to the base.
For this triangle, the area is ...
A = 1/2(4 in)(1.5 in)
A = 3 in²

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.

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.

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.

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
Answers
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.

Answers
Answer:
12 balls
Step-by-step explanation:
take 3 red balls ,5 green balls and 4 yellow balls that 12 balls = 6 balls in bag
If bag contains 4 white balls, 6 yellow balls, and 5 red balls then 6 balls can be chosen if there must be 2 balls of each color in 900 ways
What are permutation and combination?Permutation is way of selecting and arranging things while combination is way of selecting things .
here, we have,
Given that bag contains 4 white balls, 6 yellow balls, and 5 red balls
we have to select 6 balls
it's given that there must be 2 balls of each color
So here's how we can select them
2 white balls ,2 yellow balls and 2 red balls
So we have to select 2 white balls out of 4 white balls ,2 yellow balls out of 6 yellow balls and 2 red balls out of 5 red balls
so number of ways of selecting
4C2 * 2C2 * 5C2
=6*15*10
=900
If bag contains 4 white balls, 6 yellow balls, and 5 red balls then 6 balls can be chosen if there must be 2 balls of each color in 900 ways

Which of the following are point-slope equations of the line going through (-3,-5) and (2,4)
Answers
Answer:
y+5 = 9/5(x+3)
y - 4 = 9/5(x-2)
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 4- -5)/(2 - -3)
= ( 4+5)/(2+3)
= 9/5
Then using the point slope form
y -y1 = m(x-x1) where x1 and y1 are a point on the line
y - -5 = 9/5(x- -3)
y+5 = 9/5(x+3)
or using the other point
y - 4 = 9/5(x-2)
Yesterday, the price of a can of beans at five supermarkets was $1.92, $2.01,

supermarkets?
A. $2.24
B. $2.14
C. $2.04
D. $2.34
SUBMIT
Answers
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
Therefore the second option is correct

Answers
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
