I believe it is

Answer:

-7, $\frac{37}{80}$ , $\frac{15}{16}$

Step-by-step explanation:

Since -7 is the only negative shown, its the least number since negatives are less than positives. 37/80 is less than 15/16. If we multiply 15/16 by 5/5, we get 75/80. Now we can compare 37/80 to 75/80 since they have the same denominator. 37/80 is clearly less than 75/80

g Water use in the summer is normally distributed with a mean of 310.4 million gallons per day and a standard deviation of 40 mi

andreev551 [17]

Answer: The value of b = 0.99

The probability that a day requires more water than is stored in city reservoirs is 0.161.

Step-by-step explanation:

Given : Water use in the summer is normally distributed with

$\mu=310.4\text{ million gallons per day}$

Standard deviation : $\sigma=40 \text{ million gallons per day}$

Let x be the combined storage capacity requires by the reservoir on a random day.

Z-score : $\dfrac{x-\mu}{\sigma}$

$z=\dfrac{350-310.4}{40}=0.99$

The probability that a day requires more water than is stored in city reservoirs is :

$P(x>350)=P(z>0.99)=1-P(z$

Hence, the probability that a day requires more water than is stored in city reservoirs is 0.161

If we approximate the function y=sin(x) with a0+a1 x a2 x^2 +a3 x^3, what is a0,a2,a2,a3?

Rashid [163]

The coefficients $a_0,a_1,a_2,a_3$ could be chosen to be the coefficients in the Maclaurin series of $\sin(x)$ .

We have

$y = \sin(x) \approx a_0 + a_1 x + a_2 x^2 + a_3 x^3 \\\\ \implies y(0) = 0 = a_0$

$y' = \cos(x) \approx a_1 + 2a_2 x + 3a_3 x^2 \\\\ \implies y'(0) = 1 = a_1$

$y'' = -\sin(x) \approx 2a_2 + 6a_3 x \\\\ \implies y''(0) = 0 = 2a_2$

$y''' = -\cos(x) \approx 6a_3 \\\\ \implies y'''(0) = -1 = 6a_3$

It follows that $a_0=0$ , $a_1=1$ , $a_2=0$ , and $a_3 = -\frac16$ .

What is the gcf of 5 (4x-3) +x (4x-3)? Explain

TiliK225 [7]

I more or less have an understanding, but,

Factor out the GCF of 4x-3 from 5(4x-3)+x(4x-3)

Making it,

(4x-3)(5+x)
