Maximum for n=100x 40y

1 answer:

6 0

Assuming that here are the choices :
(0,0)
(5,0)
(0,8)
(2,6)

In a question like this, you just need to input the x and the y to the equation and find out which have the greatest n.

From the following above , the answer would be : (5,0)

Hope this helps

The function f is continuous son the interval [2, 10] with some of its values given in the table below. Use a right Riemann Sum

Marta_Voda [28]

The 4 subintervals are given: [2, 4], [4, 7], [7, 9], and [9, 10].

Each subinterval has length: 4 - 2 = 2, 7 - 4 = 3, 9 - 7 = 2, and 10 - 9 = 1.

Over each subinterval, we take the value of the function at the right endpoint: 3, 8, 15, and 18.

Then the integral is approximately

$\displaystyle\int_2^{10}f(x)\,\mathrm dx\approx3\cdot2+8\cdot3+15\cdot2+18\cdot1=78$

so 78.0 is the correct answer.

Future scientists: Education professionals refer to science, technology, engineering, and mathematics as the STEM disciplines. A

nalin [4]

Answer:

The probability that the proportion of freshmen in the sample of 150 who plan to major in a STEM discipline is between 0.29 and 0.37 is 0.3855

Step-by-step explanation:

The probability that the proportion of freshmen in the sample of 150 who plan to major in a STEM discipline is between 0.29 and 0.37 can be calculated by finding <em>z-scores</em> and subtracting P(z<z(0.29)) from P(z<z(0.37))

z-score in the binomial distribution of 28% of freshmen entering college in a recent year planned to major in a STEM discipline can be calculated using the equation:

$z=\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } }$ where

p(s) is proportion of freshmen we are interested (0.37, 0.29)

p is the proportion found in recent year found by research group (28% or 0.28)

N is the sample size (150)

Then z(0.37)= $z=\frac{0.37-0.28}{\sqrt{\frac{0.28*0.72}{150} } }$ ≈ 2.4550 and P(z<2.4550)=0.993

z(0.29)= $z=\frac{0.29-0.28}{\sqrt{\frac{0.28*0.72}{150} } }$ ≈ 0.2728 and P(z<0.2728)=0.6075

Then P(z(0.29)<z<z(0.37))=0.993-0.6075=0.3855

For the function y=-1+6cos(2pi/7(x-5)) what is the minimum value?

s344n2d4d5 [400]

Answer:

The minimum value of y is -7

Step-by-step explanation:

Given: $y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

We are given a cosine function.

We need to find minimum value of function.

$y=-1+6\cos(\dfrac{2\pi}{7}(x-5))$

Here y is depends on cosine function.

y is minimum when cosine is minimum because y is directly proportional to cosine function.

Minimum value of cos x is -1

Therefore, For minium value of y

$\cos(\dfrac{2\pi}{7}(x-5))=-1$

Minimum value of y

$y=-1+6(-1)$

$y=-7$

Hence, The minimum value of y is -7

The sum of all the exponents on all the variables of a term<br> plsss answer

kolbaska11 [484]

Answer:

Answer: for polynomials in two or more variables, the degree of a term is the sum of the exponents of the variables in the term; the degree (sometimes called the total degree) of the polynomial is again the maximum of the degrees of all terms in the polynomial
