pool is22.5 cm. She walks one round every morning before diving in the pool.
How far does she walk around the pool every morning? *
70.65
141.3
35.33
282.6
Answer:
Total walk she did around the pool every morning = 141.3
Step-by-step explanation:
Given - Kriti has a circular swimming pool in her house. The radius of the swimming pool is 22.5 cm. She walks one round every morning before diving in the pool.
To find - How far does she walk around the pool every morning?
Proof -
Given that, the swimming pool is circular in shape.
So,
1 round of circle = Circumference of circle.
As we know that,
Circumference = [tex]2\pi r[/tex]
= [tex]2*\pi *22.5[/tex]
= 141.3
∴ we get
Total walk she did around the pool every morning = 141.3

Raise 1.00203333 to the negative 360 power
Answer:0.4813042802
Step-by-step explanation:
Suppose the function:
f(x) = 2.9646 (1.0170)x
models the world population x years after 1948.
Rewrite the exponential equation given above using base e.
f(t) = 2.9646 e ^(0.0169) t
B.
f(t) = 2.9646 (1.0170) e^t
C.
f(t) = 2.9646 + 1.0170e^t
D.
f(t) = 2.9646 e^(1.0170t)
E.
f(t) = 2.9646 e^ln (1.0170t)
Given:
The function is:
[tex]f(x)=2.9646(1.0170)^x[/tex]
To find:
Rewrite the exponential equation given above using base e.
Solution:
The exponential models is:
[tex]f(x)=P(1+r)^x[/tex] ...(i)
Where P is initial values, r is the rate of interest and x is the time period.
The exponential models using base e is:
[tex]f(t)=Pe^{rt}[/tex] ...(ii)
Where, P is initial values, r is the rate of interest and t is the time period.
The given function is:
[tex]f(x)=2.9646(1.0170)^x[/tex]
It can be written as:
[tex]f(x)=2.9646(1+0.0170)^x[/tex] ...(iii)
On comparing (i) and (iii), we get
[tex]P=2.9646[/tex]
[tex]r=0.0170[/tex]
Putting [tex]P=2.9646[/tex] and [tex]r=0.0170[/tex] in (ii), we get
[tex]f(t)=2.9646e^{0.0170t}[/tex]
Therefore, the correct option is D.
High blood pressure has been identified as a risk factor for heart attacks and strokes. The National Health and Nutrition Examination Survey reported that the proportion of U.S. adults with high blood pressure is 0.3. A sample of 38 U.S. adults is chosen. (a) Is it appropriate to use the normal approximation to find the probability that more than 40% of the people in the sample have high blood pressure? If so, find the probability. If not, explain why not. (b) A new sample of 80 adults is drawn. Find the probability that more than 40% of the people in this sample have high blood pressure. (c) Find the probability that the proportion of individuals in the sample of 80 who have high blood pressure is between 0.23 and 0.32.

• 13.5
• 5.1
• 6.9
• 8.6
Answer:
8.6
Step-by-step explanation:
Use the law of cosines
[tex]d^{2} = e^{2} + f^{2} -2ef cos D[/tex]
[tex]d^{2} = 9^{2} + 13^{2} - 2(9)(13) cos 41\\ = 81 + 169 - 176.602\\ = 73.3979\\d = \sqrt{73.3979} = 8.6[/tex]

Other root of equation, [tex]\frac{8}{3}[/tex]

To solve this problem, one could use Vieta's theorems. Vieta's theorems state the following, let ([tex]x_1[/tex]) and ([tex]x_2[/tex]) represent the roots of the equation,
[tex](x_1)+(x_2)=-\frac{b}{a}[/tex]
[tex](x_1)(x_2)=\frac{c}{a}[/tex]
Substitute the given values into the equation,
[tex]3+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=\frac{24}{3}[/tex]
Simplify,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=8[/tex]
Inverse operations,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex]x_2=\frac{8}{3}[/tex]
Substitute in the value of ([tex]x_2[/tex]),
[tex](3)+(\frac{8}{3})=-\frac{b}{3}[/tex]
Simplify, convert to improper fractions and combine like terms,
[tex]\frac{9}{3}+\frac{8}{3}=-\frac{b}{3}[/tex]
[tex]\frac{17}{3}=-\frac{b}{3}[/tex]
Multiply both sides of the equation by ([tex]3[/tex]) to remove the denominator,
[tex]17=-b[/tex]

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they study in a week.
Part A: What is the group of points labeled N called? What is the point labeled M called? Give a possible reason for the presence of point M.
Part B: Describe the association between students’ test scores and the number of hours they study.
Answer:
Step-by-step explanation:
m is called an outlier and it is a positive association
Answer:
Part A) Part N.) is called the cluster of the whole chart. Part M.) is called the outlier because it's not with the rest of the group, therefore, it's the outlier of the group.
Part B.)
The association between the students' test scores and the number of hours they've studied is a positive correlation. That means the longer the students spent time studying for their tests... the better grades they got because of it. It's a lot like a cause-and-effect kind of situation.

How many solutions does the equation 5x + 3x − 4 = 10 + 8x have? (4 points)
a
No Solution
b
One
c
Two
d
Infinitely many
Step-by-step explanation:
[tex]5x + 3x - 4 = 10 + 8x \\ 8x - 4 = 10 + 8x \\ 8x - 8x = 10 + 4 \\ = 14[/tex]
Since x has been eliminated (8x-8x = 0), there are no solutions in this equation.

Answer:
3 + 7 + 2= 12
Step-by-step explanation:
It is made true because the equation adds up to the number. If we take 3+7 it equals to 10. Then we take 10 and add it to 2, which gives us 12.

The value of the missing number x will be 10.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Let the missing number be x. Then the equation can be written as,
3 + 7 + 2 = x + 2
Simplify the equation, then the value of the variable x will be
3 + 7 + 2 = x + 2
3 + 7 + 2 - 2 = x
x = 3 + 7
x = 10
The value of the missing number x will be 10.

A worker places tape around a rectangular shipping label that is 2 times longer than it is wide. How much tape does the worker need? The width is 74mm
Answer:
444 :) (angel number, haha)
Step-by-step explanation:
it needs 74 times 2 mm which is 148 I think, which will also be the length since 148 is 2 times more than 74
so it's : 74 + 74 + 148 + 148 which is basically just 148 times three, so the answer is 444!

so 7 x 12 = 84
you would win $84, you bet 7 so net profit would be 84-7 = $77
Net profit is $77
