This week, 957 people went to the beach. Last week, 1,207 people went to the beach. The number of people who went to the beach

kati45 [8]

Answer:

Less than 25%

Step-by-step explanation:

1. Find the difference of the two numbers: 1,207 - 957 = 250

decrease = original number - new number

2. Then, divide the decrease by the original number

250/1,207 = 0.207

3. Multiply the answer by 100 to get the percentage

0.207 x 100 = 20.7%

Therefore, the number of people fell by 20.7%

Hence, the answer is less than 25%

Average Rate of Change: $\displaystyle \displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

<u>Step 1; Define</u>

<em>Identify</em>

f(x) = 5ˣ + 1

Interval <em>x</em> [0, 4] →<em>b</em> = 4, <em>a</em> = 0

<u>Step 2: Find Rate of Change</u>

Substitute in variables [Average Rate of Change]: $\displaystyle \displaystyle \frac{f(4) - f(0)}{4 - 0}$
[Average Rate of Change] Substitute in <em>x</em> [Function f(x)]: $\displaystyle \displaystyle \frac{(5^4 + 1) - (5^0 + 1)}{4 - 0}$
(Parenthesis) Evaluate exponents: $\displaystyle \displaystyle \frac{(625 + 1) - (1 + 1)}{4 - 0}$
(Parenthesis) Add: $\displaystyle \displaystyle \frac{626 - 2}{4 - 0}$
[Fraction] Subtract: $\displaystyle \displaystyle \frac{624}{4}$
Divide: $\displaystyle \displaystyle 156$

Find P(Y|B) from the information in the table.

vova2212 [387]

Answer:

0.4

Step-by-step explanation:

The table with correct formatting is attached in the image below.

We have to find P(Y | B). This is a conditional probability i.e. probability of Y given B.

The formula of conditional probability for two event A and B is:

$P(A|B)=\frac{P(A \cap B)}{P(B)}$

So, for the given case, the formula would be:

$P(Y|B)=\frac{P(Y \cap B)}{P(B)}$

P(Y ∩ B) indicates the probability of Y and B occurring together. Y and B occur together 34 times out of total of 324, so:

$P(Y \cap B)=\frac{34}{324}$

P(B) indicates the probability of occurrence of B. B occurs 85 times in a total of 324. So,

$P(B)=\frac{85}{324}$

Using these values in the formula of conditional probability, we get:

$P(Y \cap B)=\frac{\frac{34}{324}}{\frac{85}{324} }\\\\ =\frac{34}{85}\\\\ =0.4$

Thus, the value of P(Y|B) is 0.4

What is the mass, in grams, of a liquid having a density of 1.50 g/ml and a volume of 3.50 liters

valina [46]

Answer:

5250 g

Step-by-step explanation:

Given : Density of liquid is 1.50 g/ml

Volume of liquid is 3.50 liters

Solution :

Since 1 liter = 1000 ml

So, Volume of liquid is 3.50 liters = 3.5*1000 = 3500 ml.

Now $volume = \frac{mass}{density}$

$3500 = \frac{mass}{1.50 }$

$3500 * 1.50=mass$

$5250 g = mass$

Hence , the mass of the liquid is 5250 g.
