Answer:
False
Step-by-step explanation:
Let us check using Pythagorean Theorem
Where c is the hypotenuse (14), a is the base (13) and b is the perpendicular (5)
Putting in the above formula
196 = 169+25
196 ≠ 194
So, It is not a right angled triangle
Answer:
2x^3 - 2x^2 - 12x
Step-by-step explanation:
2x(x - 3)(x + 2)
= 2x ( x^2 + 2x -3x - 6)
= 2x (x^2 - x - 6)
= 2x^3 - 2x^2 - 12x (answer).
4 days.
If it takes 6 days for 8 people to pick apples then it must take 48 days for 1 person to do it because 6•8=48.
So then it must take 12 people
48/12 days which is 4 to pick apples from trees.
Answer:
4t+6
Step-by-step explanation:
To find the perimeter of the rectangle you add the length of the sides.
Perimeter= t+ t+ t+ 3+ t+ 3= <u>4t+6</u>
or
Perimeter=2(t)+ 2(t+3)= 2t+ 2t+ 6= <u>4t+6</u>
The residual value comes out to be 2.94 cm and height is 157.06 cm
<u>Explanation:</u>
The regression equation is calculated at the first step.
height = 105.08 plus 2.599 multiply foot length
At foot length = 20cm, height = 105.08 plus 2.599 multiply 20
= 157.06 cm
Residual = Actual minus predicted value = 160 minus 157.06
=2.94 cm
B) The residual standard deviation generally gives a sense of the goodness of fit of goodness of regression equation on our data. The magnitude tells us that how much will be predicted values from model will vary from actual values. the linear model is justified.
