Answer: The answer is 165
Step-by-step explanation:
Those who will visit the garden more than 3 times in the next month will be those who visit 4, 5, and 6 or more times.
Out of the 75 surveyed, the total number of those are:
= 9 + 12 + 3
= 24
That would give a percentage of:
= 24 / 75
= 32%
This means that the best estimate for those who will visit more than 3 times is 32%.
Out of the total number of 516, that is:
= 32% * 516
= 165 members

Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
since we know the Hyp and the Opp of the angle pick SOH
Sin(Ф)= 42 / 42[tex]\sqrt{2}[/tex]
∅ = arcSin( 42 / 42[tex]\sqrt{2}[/tex] )
∅ = 45 °

Show work pleaseeeeee
Answer:
148cm²
Step-by-step explanation:
seriously why, just why? okay, hold on, we're gonna be here a while
Let's start with the triangles, they're all equal, and we already have their measurements and the formula for the area of a triangle is base x height ÷ 2, so all we have to do is plug:
5 x 8 = 40
40 ÷ 2 = 20
Now we have to multiply by 3 because there's 3 of these abominations:
20 x 3 = 60
So we put that on a back burner while we do the semicircle
So the formula for the area of a circle is pi x radius², so we have to find the radius. We know that each of the triangle bottoms is 5cm, so we just multiply by 3:
5 x 3 = 15
So the diameter of the semicircle is 15cm, now we divide that by two to find the radius:
15 ÷ 2 = 7.5
Now we just plug that into our formula (we're using 3.14 for pi)
7.5² = 56.25
3.14 x 56.25 = 176.625
Usually, we'd stop there, but it's only half of a circle, so:
176.625 ÷ 2 = 88.3125
So now we add both of our areas:
60 + 88.3125 =
148.3125
Normally, that would be the answer, but since we're supposed to be estimating, we round it to the nearest whole number:
148.3125 -> 148
So the area of the figure is 148cm²
if this is wrong, let me know so I can fix it

Answer:
f the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
Step-by-step explanation:
Answer:
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.

Answer:
12
Step-by-step explanation:
Okay, so on a grid, points Q and R are parallel to each other on the point 6, we just have to figure out how far apart they are, and to figure that out, we have to find the distance between 8 and -4 so:
8 - -4 = 8 + 4 = 12
So, the distance from point Q to point R is 12

Answer:
The exponential equation is y = -2×(1/2)^x
Step-by-step explanation:
1) The horizontal asymptote of the function is the x axis (always nice)
2) At x=0, y=-2 (i.e, this function will be multiplied by -2 bc the exponent part will transform into one at x=0)
3) Then we need to ascertain the base of the exponential. Based on the facts that at x=1, y=-1 and the "a-value" is -2, we can set up an equation to find b:

Charles can ride his bike 4 miles in 20 minutes. Which of the following ratios show the number of miles to minutes Charles can ride his bike?
A
24:1
B
1:4
C
4:24
D
1:5
Answer:
D.) 1:5
Step-by-step explanation:
The reason why it's D is because when you simplify the original ration, 4:20, you get the simplified answer of 1:5. When you divide each side by 4, you get the ratio of 1:5.
So, D.) 1:5

Ramon drew boxplots to summarize the number of pages in each chapter of two books. The value of the interquartile ranges of these boxplots are the same. Which boxplots could represent this data?
Answer:
The answer is c
Step-by-step explanation:
The middle line is in the same spot
The boxplot that could represent this data is boxplot B.
What is the interquartile range?
An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
Ramon drew boxplots to summarize the number of pages in each chapter of two books.
The value of the interquartile ranges of these boxplots is the same.
So,
We see that,
Box plot B has the same interquartile range.
i.e
35 - 20 = 15
30 - 15 = 15
This is the only boxplot that has the same interquartile ranges.
Thus,
Box plot B has the same interquartile range.
