Step-by-step explanation:

$y = {24x}^{2} - 15x + 56x - 35$

$y = 24x {}^{2} + 41x - 35$

$\frac{dy}{dx} = 48x + 41$

Answer:

Step-by-step explanation:

use uv rule= uv'+vu'

u=3x+7

u'=3+0=3

v=8x-5

v'=8-0=8

uv= (3x+7)(8)+(8x-5)(3)

=24x+56+24x-15

=48x+41

All Seasons Plumbing has two service trucks that frequently need repair. If the probability the first truck is available is 0.75

oksano4ka [1.4K]

Answer: There is a probability of 0.05 that there is neither truck is available.

Step-by-step explanation:

Since we have given that

Probability that the first truck is available = 0.75

Probability that the second truck is available = 0.50

Probability that both trucks are available = 0.30

So, probability that either first truck or second truck is available is given by

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\P(A\cup B)=0.75+0.50-0.30\\\\P(A\cup B)=0.95$

We need to find the probability that neither truck is available.

so, P(A∪B)'=1-P(A∪B)

$P(A\cup B)'=1-0.95=0.05$

Hence, there is a probability of 0.05 that there is neither truck is available.

What is 2/5% of 820? 1.8 2.05 2.88 3.28

Margarita [4]

Answer:

D) 3.28

Step-by-step explanation:

820/x=100/2.5

(820/x)*x=(100/2.5)*x - we multiply both sides of the equation by x

820=40*x - we divide both sides of the equation by (40) to get x

820/40=x

20.5=x

x=20.5

now we have:

2.5% of 820=20.5
