Jamie makes a road through his wooded lot. What is the area of the part of the lot that has trees?

fredd [130]

since the area formula is length times width,72 times 36 = 2592 then that times 6 = 15552.That is the area of the lot that has trees.

Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace t

KengaRu [80]

Answer:

0.139

Step-by-step explanation:

We are given that

Total number of cards=52

n=18

We have to find the probability of drawing at least 7 spades

Total number of spaded in deck of 52 cards=13

Probability of getting spade= $p=\frac{13}{52}=\frac{1}{4}$

Probability, $P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}$

Probability of getting no spade= $q=1-p=1-\frac{1}{4}=\frac{3}{4}$

By binomial theorem of probability

$P(X=x)=\binom{n}r}p^rq^{n-r}$

P(x $\geq 7)=1-P(x\leq 6)$

The probability of drawing at least 7 spades= $1-\sum_{r=0}^{6}\binom{18}{r}(\frac{3}{4})^{18-r}(\frac{1}{4})^r$

The probability of drawing at least 7 spades=0.139

Decide whether or not each equation represents a proportional relationship. A.The remaining length (L) of 120-inch rope after x

bulgar [2K]

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

$\frac{y}{x}$ = m

m is a constant value, which means is the same.

A. Equation: 120 - x = L

Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.

B. Equation: 1.08p = t

Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

$\frac{t}{p}=1.08$

C. Equation: $x=\frac{m}{4}$

This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

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

D. Equation: $V=12s^{2}$

This equation is NOT proportional because side length is squared, so it is not constant linearly.
