Mathematics
1 answer:
ELEN [110]3 years ago
5 0

Answer:

B)

Explanation:

The equation of the line is y-2=(-2/5)(x-0) which is 2x+5y-10=0

Putting (0,0) in the above equation, we have: 2(0)+5(0)-10=-10≤0.

Thus the required area is 2x+5y≤10.

Also, since the X and Y coordinates are positive, we have x≥0 and y≥0

<h3>Answer:</h3>

\displaystyle x^{\frac{2}{3}}

<h3>Step-by-step explanation:</h3>

The rules of exponents tell you ...

... (a^b)(a^c) = a^(b+c) . . . . . . applies inside parentheses

... (a^b)^c = a^(b·c) . . . . . . . . applies to the overall expression

The Order of Operations tells you to evaluate inside parentheses first. Doing that, you have ...

... x^(4/3)·x^(2/3) = x^((4+2)/3) = x^2

Now, you have ...

... (x^2)^(1/3)

and the rule of exponents tells you to multiply the exponents.

... = x^(2·1/3) = x^(2/3)

MAVERICK [17]

Answer:

Max: 500

Min: 492

Step-by-step explanation:

Her dog is on an 8 meter leash but it doesn't necessarily take up the whole leash. The most is could be closer to her house than Morgan is 8 meters, the least is 0.

Most: 500-0=500

Min: 500-8=492

Please rate, thank, and mark branliest (not necessarily mine) Hope this helps :)

Jennifer bought 12 pens. Out of 12 pens, 7 are blue and the rest are red.
alexdok [17]

Answer:

The answer is 5:12

Step-by-step explanation:

It is 5:12 because We already know that 7 pens are blue. To find the number of red pens we must subtract 12 - 7 and get 5 as the number of red pens. Now knowing the no. of red pens and total number we can say the ratio of red pens to total no. is 5:12

Suppose a simple random sample of size nequals45 is obtained from a population with muequals64 and sigmaequals14. ​(a) What must
jeka94

Answer:

Step-by-step explanation:

Given that sample size = n=45

mu = 64 and sigma =14

a) Sample mean will follow a normal distribution irrespective of the original distributions provided

i) samples are randomly drawn

ii) samples represent the population

iii) Sample size is sufficiently large

b) Here we have sample std dev= \frac{\sigma}{\sqrt{n} } \\=\frac{14}{\sqrt{45} } \\=2.09

P(X bar>68.1) = P(Z>\frac{68.1-64}{2.09} \\=P(Z>1.96)\\=0.25

c) P(X bar>66.3) = P(Z>\frac{66.3-64}{2.09} \\=P(Z>1.10)\\=0.136
