Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.

Agata [3.3K]

Double every year
year one
4 times 2
year 2
4 times 2 times 2 aka 4 times 2^2
year 3
4 times 2 times 2 times 2 aka 4 times 2^3
obviously

at year 'n' the number of rabbits will be
4 times 2^n

You claim you are psychic and can predict a coin flip 60% of the time. To test your claim, your friend has you predict a coin fl

Salsk061 [2.6K]

Answer:

You can reject the null at the 10% and 5% level of significance, but cannot reject the null at the 2%, or 1% level of significance. ( D )

Step-by-step explanation:

let : P = 0.6

x = 135 , n = 200

p = 135 / 200 = 0.675

H0 : P = 0.6

Ha : P ≠ 0.6

performing the test statistic = ( 0.675 - 0.6 ) / $\sqrt{\frac{0.60(1-0.60)}{200} }$

= 0.075 / 0.0346 ≈ 2.17

p-value = 2 * P ( Z > - 2.17 ) ( using excel function ; NORMSDIST )

= 2 * 0.015 = 0.03

NEED HELP ASAP 30 POINTS WILL BE GIVEN TO BRAINLIEST

WINSTONCH [101]

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$G(-1,3)\ H(1,2)\ J(-3,-1)$

Step 1

Find the slope GH

$G(-1,3)\ H(1,2)$

substitute in the formula

$m=\frac{2-3}{1+1}$

$m=\frac{-1}{2}$

$mGH=-\frac{1}{2}$

Step 2

Find the slope HJ

$H(1,2)\ J(-3,-1)$

substitute in the formula

$m=\frac{-1-2}{-3-1}$

$m=\frac{-3}{-4}$

$mHJ=\frac{3}{4}$

Step 3

Find the slope JG

$J(-3,-1)\ G(-1,3)$

substitute in the formula

$m=\frac{3+1}{-1+3}$

$m=\frac{4}{2}$

$mJG=2$

Step 4

Verify if triangle GHJ is a right triangle

we know that

if two lines are perpendicular, then the product of their slopes is equal to minus one

$m1*m2=-1$

compare slope GH with slope JG

we have

$mGH=-\frac{1}{2}$

$mJG=2$

$-\frac{1}{2}*2=-1$ -----> side GH and side JG are perpendicular

The triangle GHJ is a right triangle

The degree of 5x4y2z3 is 9. O True O False

pashok25 [27]

Answer:

true

Step-by-step explanation:

because the expression shown is a monomial we simply add the degrees of each term

4 + 2 + 3 = 9

5x4y2z3 indeed has a degree of 9

Note: if the terms were being added we take the highest degree and that is the degree of the expression.

ex. 5x^4 + y^2 + z^3 would have a degree of 4
