Answer:
The percent decrease in the number of people who went to the pool over these four weeks was of 20%.
Step-by-step explanation:
Percent decrease:
The percent decrease is the decrease multiplied by 100 and divided by the initial value.
Decrease was of:
Second week: - 125
Third week: - 125 + 145
Fourth week: -125 + 145 - 224 = -204
Decrease was of 204.
Percent decrease:
Initially 1,020, then a decrease of 204. So
204*100%/1020 = 20%
The percent decrease in the number of people who went to the pool over these four weeks was of 20%.
Answer: 20%

A sprinkler is designed to water a circular area that has a radius of 7 feet. The sprinkler is located at (0,0) on a lawn. A flowerbed is planted 3 feet east and 6 feet south of the sprinkler.
Determine if the distance from the flowerbed to the sprinkler places the flowerbed on or within the circular area that this sprinkler can water.
No. The flowerbed is 18 feet away from the sprinkler, which is more than the 7-foot radius.
Yes. The flowerbed is exactly 7 feet away from the sprinkler.
No. The flowerbed is 9 feet away from the sprinkler, which is more than the 7-foot radius.
Yes. The flowerbed is √45 feet away from the sprinkler, which is less than the 7-foot radius.
Yes. The flowerbed is √45 feet away from the sprinkler, which is less than the 7-foot radius.
Given that,
A circular area that has a radius of 7 feet.The sprinkler is located at (0,0) on a lawn.A flowerbed is planted 3 feet east and 6 feet south of the sprinkler.Based on the above information, the calculation is as follows:
[tex]= \sqrt(3^2 + 6^2) \\\\= \sqrt45[/tex]
= 6.7m
Therefore the above statement should be considered true.

Step-by-step explanation:
In rolling two dice, what is the probability that the sum of the two numbers on the dice will be 4?
A: 1 over 12
B: 3
C: 11 over 12
D: 2 over 3
Answer:
A
Step-by-step explanation:
If the dice are fair and 6 sided then you can roll a 4 in three ways
2 2
1 3
3 1
The total number of ways you can throw two 6 sided dice is 6 * 6 or 36
So P(4) = 3/36 = 1/12

Determine which solution is correct for solving StartFraction 5 over 7 EndFraction y = 6using reciprocals.
Given:
The equation is:
[tex]\dfrac{5}{7}y=6[/tex]
To find:
The solution of the given equation by using the reciprocals.
Solution:
We have,
[tex]\dfrac{5}{7}y=6[/tex]
We need to multiply both sides by the reciprocal of [tex]\dfrac{5}{7}[/tex] to isolate the variable x.
The reciprocal of [tex]\dfrac{5}{7}[/tex] is [tex]\dfrac{7}{5}[/tex]. So, multiplying both sides by [tex]\dfrac{7}{5}[/tex], we get
[tex]\dfrac{5}{7}y\times \dfrac{7}{5}=6\times \dfrac{7}{5}[/tex]
[tex]y=\dfrac{42}{5}[/tex]
[tex]y=8.4[/tex]
Therefore, the value of y is 8.4.
Answer:
42/5

Suppose Wesley is a marine biologist who is interested in the relationship between the age and the size of male Dungeness crabs. Wesley collects data on 1,000 crabs and uses the data to develop the following least-squares regression line where X is the age of the crab in months and Yˆ is the predicted value of Y, the size of the male crab in cm. Yˆ=9.1411+0.4775X What is the value of Yˆ when a male crab is 23.2417 months old?
Answer:
[tex]Y = 20.239[/tex]
Step-by-step explanation:
Given
[tex]Y = 9.1411 + 0.4775X[/tex]
Required
The predicted value of [tex]Y[/tex] when [tex]X = 23.2417[/tex]
To do this, we substitute [tex]X = 23.2417[/tex] in the given equation
So, we have:
[tex]Y = 9.1411 + 0.4775X[/tex]
[tex]Y = 9.1411 + 0.4775 * 23.2417[/tex]
[tex]Y = 9.1411 + 11.0979[/tex]
[tex]Y = 20.239[/tex]

5 x 10 = 50
Answer:
$50.00
Step-by-step explanation:
This is because 30 is 60% of 50. (100% - 40% = 60%)
You can verify this answer by calculated 40% of 50, which is 30.

Answer:
[tex]y=-\frac{5}{3} x+5[/tex]
Step-by-step explanation:
Points on the graph: (0, 5) and (3, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-5)/(3-0)
m= (-5)/3
m= -5/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -5/3(x - 0)
y - 5 = -5/3x
y = -5/3x + 5

sec 330 find the exact value in simplest form with a rational denominator
Answer:
[tex]\implies \sec 3 30^o = \dfrac{2}{\sqrt3}=\dfrac{2\sqrt{3}}{3}[/tex]
Step-by-step explanation:
Given :-
[tex]\sec 330^o [/tex]And we need to find out its value . Firstly we know that 330° lies in 4th quadrant . And In fourth quadrant , cosine and secant are positive . Therefore , the result will be positive. Now we know that ,
[tex]\implies \sec (360^o-\theta)= \sec\theta [/tex]
Using this ,
[tex]\implies \sec (330^o) \\\\\rm\implies sec(360^o-30^o) \\\\\rm\implies \sec 30^o [/tex]
And the value of sec 30° is ,
[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}[/tex]
And by question we need to write it with a rational denominator .So on rationalising the denominator , we have ,
[tex]\implies \sec 30^o = \dfrac{2}{\sqrt3}=\boxed{\red{\dfrac{2\sqrt3}{3}}}[/tex]
Hence the required answer is 2√3/3.

Answer:
7/9
Step-by-step explanation:
If the chances of an outcome are 2/9, the odds against it can be found by subtracting that from 1.
1 - 2/9
= 7/9
So, the odds against that outcome are 7/9
