A zoologist studies a population of 800 rabbits. He tags 160 rabbits at random, of which 37 have blue eyes. Based on this data,

Snezhnost [94]

Answer:

185

Step-by-step explanation:

Population size = 800

Sample size = 160

Number of blue-eyed rabbit in sample = 37

The proportion of blue-eyed rabbit in the sample is :

p = number of blue eyed rabbit / sample size

p = 37 / 160 = 0.23125

Estimated number of blue eyed rabbit in population :

p * population size

0.23125 * 800

= 185

A seed Company planted a floral mosaic of a national flag. The perimeter of the flags 540 feet. Determine the flags length and w

stiv31 [10]

Answer:

Length of the flag is 190 feet and width of the flag is 80 feet.

Step-by-step explanation:

Given:

Perimeter of the flag = 540 feet

We need to find the length and width of the flag.

Let the length of flag be 'l'.

Let the width of the flag be 'w'.

Now given:

length is 110 feet greater than the width

Length of the flag $l = 110+w$

Now we know that,

Flag is in rectangular shape.

So Perimeter of rectangle is given by 2 times sum of length and width.

framing in equation form we get;

$2(l+w) =540$

Now dividing both side by 2 we get;

$\frac{2}{2}(l+w)=\frac{540}{2}\\\\l+w =270$

Now Substituting the value of 'l' in above equation we get;

$110+w+w=270\\\\110+2w=270$

Subtracting both side by 110 we get;

$110+2w-110=270-110\\\\2w= 160$

Dividing both side by 2 we get;

$\frac{2w}{2}=\frac{160}{2}\\\\w=80\ ft$

Width = 80 feet

Length $l =110+w =110+80 =190 \ ft$

Hence Length of the flag is 190 feet and width of the flag is 80 feet.

A roast turkey is taken from an oven when its temperature has reached 185°F and is placed on a table in a room where the tempera

ANEK [815]

It is very important to look at the graph very minutely. It can be seen that at 30 minutes the slope is a little more than negative 50 and at 90 minutes it is a little less than negative 50. From this fact, it can be deduced that the estimated rate of change of the temperature after an hour would be -50/60. I hope that the answer has come to your desired help.

What is the y-intercept of the function f(x) = -2/9x+1/3?

Brilliant_brown [7]

Answer:

y- intercept = $\frac{1}{3}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

f(x) = - $\frac{2}{9}$ x + $\frac{1}{3}$ ← is in slope- intercept form

with y- intercept c = $\frac{1}{3}$

If a ∥ b and e ∥ f, what is the value of y? I'll give you brainliest if you answer correctly

Shalnov [3]

Answer:

D 92.

Step-by-step explanation:

if a || b and e || f

THEN...

x + 1 = y

y + z = 180

z = x - 3

x = 91

y = 92

z = 88

answer is 92
