Answer:

0.874 < p <0.926

Step-by-step explanation:

The population proportion lies in the interval 0.8738 < p < 0.9262 with 95% confidence.

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

Given, A sample having n = 500, p = 0.90, and we have to construct a 95% confidence interval.

We know the confidence interval for a population proportion is,

CI = [tex]P \pm Z_\frac{\alpha}{2}\sqrt{\frac{P(1 - P)}{n}}[/tex].

CI = 0.9 ± 1.96×{√(0.9×0.1)/500}.

CI = 0.9 ± 1.96×√(0.09/500).

CI = 0.9 ± 1.96×0.0134.

CI = 0.9 ± 0.0262.

Therefore,    0.9 - 0.0262 < p < 0.9 + 0.0262.

0.8738 < p < 0.9262.

Step-by-step explanation:

Using the given diagram, we want to know the equation that is true

Option A is wrong as both are on a straight line and in fact should add up to equal 180 and not be equal to each other

Option B is not correct as both are supplementary and does not equal each other

Option C is not correct, both are corresponding to each other and should not add up to 90

Option D is correct

Both angles are supplementary as they are exterior angles that add up to 180

1436.03 mm³

Step-by-step explanation:

I believe the 7mm should be the radius?

The volume of a sphere is [tex]\frac{4}{3}[/tex]πr³

[tex]\frac{4}{3}[/tex]π * 343

since pi is rounded to 3.14, we get

Which sentence compares the two functions' maximum values the most effectively?

(a)The maximum value is the same for both functions.

(b) f(x) has a greater maximum value than g(x).

(c) The greatest value of g(x) is bigger than that of f(x).

(d) The maximum values cannot be determined.

The statement that best compares the maximum value of the two functions is g(x) has a greater maximum value than f(x) that is Option (c).

The maximum value is the point at which a function reaches its peak is known as its maximum value.

To compare both functions.

Take function f(x)= [tex]-2x^{2} +9[/tex]

Differentiate the function f(x)

f'(x) = -4x

Take f'(x) as 0

-4x = 0

x = 0

Substitute x = 0 in f(x)

f(0) = [tex]-2(0)^{2} +9[/tex]

f(0) = 9

This means that the greater value of function f(x) is 9.

From the table of function g(x), the maximum is 11.

11 is greater than 9

Therefore, The greater value of g(x) is bigger than that of f(x).

Answer-

Total kicks that were attempted = 40

Explanation

Goals blocked by Kyra = 55%;

Goals which could not be blocked by Kyra = 100 - 55 = 45%

Goals made during team drill = 18

Let total kicks attempted be 'n';

Therefore;

(18/n) × 100 % = 45 %

18/n = 45/100;

n = 1800/45;

n = 40

The time period "percentage" is derived from the Latin per centum, which means "hundred" or "with the aid of the hundred".[5][6] The sign for "percentage" evolved via gradual contraction of the Italian term in line with cento, which means "for 100". The "according to" turned into regularly abbreviated as "p."—subsequently disappeared completely. The "cento" was reduced in size to two circles separated through a horizontal line, from which the present day "%" image is derived.

In mathematics, a percentage (from Latin: in line with centum, "by a hundred") is quite a number or ratio expressed as a fraction of 100. it's miles often denoted using the percentage signal, "%",[1] although the abbreviations "pct.", "pct" and sometimes "pc" also are used.[2] A percentage is a dimensionless number (natural wide variety); it has no unit of size.

Answer:36

Step-by-step explanation:

The required first and smallest term of consecutive terms is 38.

Given that,

The average of five consecutive numbers is 38. The smallest number to be determined.

The average of the values is the ratio of the total sum of values to the number of values.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

The average of five consecutive numbers is 38.
Let the middle value is a,
Series of 5 number can be given as = (a -2n) , (a-n) , a , (a+n) , (a+2n).
n = 5
Average = ( a-2n +a -n + a +a+n+ a+2n)/5
38 = 5a/5
a = 38
Now smallest and first term (n = 1)   = a - 2n
                                                     = 38 - 2(1)
                                                     = 36

Thus, the required first and smallest term of consecutive terms is 38.

Two terms between the 1st and the 4th in the given geometric sequence is 21 and 147.

The formula for the nth term in a geometric sequence is given by:

a(n) = a(1) . rⁿ⁻¹

Where:

a(1) = first term

r = common ratio

Parameters given:

a(1) = 3

a(4) = 1029

Substitute n  = 4 into the formula:

a(n) = a(1) . rⁿ⁻¹

a(4) = 3 . r³

1029 = 3 . r³

r³ = 1029/3 = 343

r = 7

Two terms between the 1st and the 4th term is a(2) and a(3).

In a geometric sequence, the following applies:

a(n) = a(n-1) . r

Hence,

a(2) = 3 . r

       = 3 . 7 = 21

a(3) = a(2) . r

       = 21 . 7 = 147

So interest rate is 8% per annum

Step-by-step explanation:

Principal amount = $3,006

Amount at end = $3,967.92

Time = 4yrs

interest money = ($3967.92 - $3006)  

also equal to = 4 * (x/100) * $3,006

Where x is the interest rate per annum

So, 4 * (x/100) * $3,006 = ($3967.92 - $3006)

        x = 8%

So interest rate is 8% per annum
