exis [7]2 years ago

Answer:

7.2

Step-by-step explanation:

First differences:

0.8-0.2, 1.8-0.8, 3.2-1.8, 5.0-3.2

0.6, 1.0, 1.4, 1.8

Second differences:

1.0-0.6, 1.4-1.0, 1.8-1.4

0.4, 0.4, 0.4

For the next term, add 0.4 to the last term from the first differences, and add the sum to the last term of the quadratic sequence:

0.4+1.8=2.2

2.2+5.0=7.2

∴ The next term in the sequence is 7.2

guajiro [1.7K]

Answer:

8.47 Hours

Step-by-step explanation:

Allen can take 16 hours, while

Brianne can take 18 hours;

Therefore, in 1 hour Allen will complete a fraction of 1/16, while

in 1 hour Brianne will complete a fraction of 1/18

When working together, in 1 hour they will complete a fraction of (1/18+1/16)

= 17/144,

Therefore; to complete the whole project working together, they will take;

144/17 = 8.47 hours

Does anyone know the answer?

Answer:

We conclude that the area of the right triangle is:

$A\:=p^2-2p-3$

Hence, option A is correct.

Step-by-step explanation:

From the given right-angled triangle,

Base = p+1

Perpendicular = 2p-6

Using the formula to determine the area of the right-angled triangle

Area of the right triangle A = 1/2 × Base × Perpendicular

$=\frac{1}{2}\left(p+1\right)\left(2p-6\right)$

Factor 2p-6: 2(p-3)

$=\frac{\left(p+1\right)\times \:2\left(p-3\right)}{2}$

Divide the number: 2/2 = 1

$=\left(p+1\right)\left(p-3\right)$

$\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

$=pp+p\left(-3\right)+1\cdot \:p+1\cdot \left(-3\right)$

$=pp-3p+1\cdot \:p-1\cdot \:3$

$=p^2-2p-3$

Therefore, we conclude that the area of the right triangle is:

$A\:=p^2-2p-3$

Hence, option A is correct.

We have a null hypothesis that u=3.75, but we are reluctant to accept this as the population value in case the true value is dif

Gala2k [10]

Answer:

option A

Step-by-step explanation:

To Test

H₀ : μ = 3.75

H₁ : μ ≠ 3.75

now,

If μ = 3.95 then it means H₀ is not true.

then the probability is rejecting the null hypothesis.

Hence, the probability is the power of the test against the alternative μ=3.95

The correct answer is option A
