The average weight of full-grown beef cows is 1,470 pounds with a standard deviation of 230 pounds. if the weights are normally

creativ13 [48]

Answer: The percentile is 89

Step-by-step explanation:

This question can be solved using concept for t tables

In a normal distribution the curve. $\mu= 1470 , \sigma = 230, x=1750$

The relationship between z score, mean and standard deviation is given by

$x = \mu+z\sigma$

So the z value according to this is given by the formula

$1750=1470+z(230)\\ z=\frac{280}{230} \\\\z = 1.217$

From the z table we can infer that p value for z=+1.217 is 88.82

So 1750 is 89th percentile

Need help with these two questions

WITCHER [35]

Answer:

Step-by-step explanation:

Answer:(A)= (-x^11)/(y^7)

(B)= (1/12xy^5)

Step-by-step explanation:

(A) (3x^3y^-2)(-2x^-3y^2)^-5/(6x^7y^-5)

[(3x^3y^-2)(-2x^15y^-10)]/(6x^7y^-5)

(6x^18y^5)/(-6x^7y^12)

(-6x^11)/(6y^7)

(-x^11)/(y^7)

(B) [(12x^-3y^5)/(x^-4)]^-1

(1/12xy^5)

A team from the high school went on a science-and-math quiz show. The science questions were worth 1 point and the math question

pentagon [3]

Answer:

for science the number of question is 3

And, for math it would be 5

Step-by-step explanation:

The computation is shown below:

Total questions answered is 8

And, earned points is 13

Let us assume the science question be x

And, the math question be y

Now the equation would be

x + 2y = 13

And the second equation would be

x + y = 8

Now solve the both equation

y = 5

So, the x = 3

hence, for science the number of question is 3

And, for math it would be 5

Digiron [165]

1. Y increases by 5 each time to the x value. So y=5x

2. No, y does not vary with x in this table

Glad I could help! ^-^
