Answer:

0.9962

Step-by-step explanation:

The objective of this question is to determine the proportion of average city temperature that is lower than that of Singapore.

Suppose X is a random variable that follows a normal distribution:

Then;

\(X \sim N ( \mu = 20.66, \sigma = 2)\)

\(P(X< 26) = P \bigg ( Z < \dfrac{26 - 20.66}{2} \bigg)\)

\(P(X< 26) = P \bigg ( Z < \dfrac{5.34}{2} \bigg)\)

\(P(X< 26) = P \bigg ( Z < 2.67\bigg)\)

From the z tables;

P(X< 26) = 0.9962

Thus, there is 0.9962 proportion of average city temperature are lower than that of Singapore.

Answer:

0.9962

Step-by-step explanation:

A set of average city temperatures in May are normally distributed with a mean of 20.66 degrees and a standard deviation of 2 degrees. The average temperature of Singapore is 26 degrees

What proportion of average city temperatures are lower than that of Singapore?

Solution:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

\(z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation\)

Given that μ = 20.66, σ = $2

For the average temperature of Singapore of 26°, the z score is:

\(z=\frac{x-\mu}{\sigma}=\frac{26-20.66}{2} =2.67\)

From the normal distribution table, P(x < 26) = P(z < 2.67) = 0.9962

Answer:

45

Step-by-step explanation:

put 24 over 1 to make it a fraction.

So now its:

24/1 divided by 8/15

Now cross multiply

So now its:

24*15/1*8

(24 times 15)

Over

(1 times 8)

=360/8

=45

24 divided by 8/15 is equal to 45.

To divide 24 by 8/15, we can simplify the problem by multiplying 24 by the reciprocal of 8/15, which is 15/8. Multiplying fractions involves multiplying the numerators and denominators.

So, 24 divided by 8/15 can be rewritten as 24 multiplied by 15/8:

24 * (15/8)

When we multiply the numerators (24 * 15) and the denominators (1 * 8), we get:

360/8

Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor, which is 8:

45/1

Therefore, 24 divided by 8/15 is equal to 45.

Answer:

-19.

Step-by-step explanation:

4 + 7 + 9 + 5 - 44

Doing the adds first;

= 25 - 44

= -19.

So, y = (1/2)(x + 8) is the equation of the linear function.

To write the equation of a linear function with a given x-intercept and y-intercept, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

In this case, we are given that the x-intercept is (-8, 0) and the y-intercept is (0, 4). We can use the coordinates of the x-intercept as (x1, y1) and the slope of the line as m to write the equation:

y - 0 = m(x - (-8))

y = m(x + 8)

We can then substitute the y-intercept into this equation to find the value of m:

4 = m(0 + 8)

4 = 8m

m = 1/2

Substituting the value of m back into the equation, we get:

y = (1/2)(x + 8)

This is the equation of the linear function.

Answer:

PC = 14.42 cm

Step-by-step explanation:

If a tangent and secant are drawn from a point outside a circle, then the product of the lengths of the segments of the secant is equal to the square of the length of the tangent.

PC² = PB × BD

PC² = 4 × 52

PC² = 208

PC = \(\sqrt{208}\)

PC = 14.42 cm

The length of PC=14.42 cm.

when a tangent and secant are drawn from a point outside a circle, then the multiplication of the lengths of the segments of the secant is equal to the square of the length of the tangent.

PC² = PB × BD

Use the given value in above formula we get,

PC² = 4 × 52

PC² = 208

\(PC = \sqrt{208}\)

Therefore we get the value of PC is,PC = 14.42 cm.

Therefor the length of PC=14.42 cm.

Mrs. Haley's son mowed the most part lawn more than his mother.

\($\frac{9}{28}$\) part of the lawn still needs to be mowed.

As per the given data, Mrs. Haley mowed \(\frac{1}{4}\) part of her lawn.

Also her son mowed \(\frac{3}{7}\) part of lawn

First, make equal the denominator.

The lawn was mowed by Mrs. Haley:

\(& =\frac{1}{4}=\frac{1\times 7}{4 \times 7}=\frac{7}{28} \\\)

The lawn mowed by Mrs. Haley's son:

\(&=\frac{3}{7}=\frac{3\times 4}{7 \times 4}=\frac{12}{28}\)

Mrs. Haley's son mowed the most, \($\frac{12}{28}$\).

Now we have to determine how much of the lawn still needs to be mowed.

Let the remaining part that is to be mowed be 'x'.

And let the whole part be '1'.

Subtract the part that was mowed by Mrs. Haley and her son from the whole part in order to find the remaining part to be mowed.

\(x=1-(\frac{7}{28}+\frac{12}{28})\)

\(x=1-\frac{19}{28}\)

\(x=\frac{28-19}{28}\)

\(x=\frac{9}{28}\)

Therefore the lawn still needs to be mowed is \($\frac{9}{28}$\) .

The expressions that represent the perimeter of the pool are given as follows:

The perimeter of a rectangle of length l and width w is calculated as follows:

P = 2(l + w).

The length is 3 more than 2 times the width, hence the expression is given as follows:

l = 3 + 2w.

Thus the expression for the perimeter is given as follows:

P = 2(3 + 2w + 2)

P = 6 + 6w.

The perimeter can also be written as a function of the length, as follows:

l = 3 + 2w.

2w = l - 3

w = 0.5l - 1.5.

Then the perimeter is given as follows:

P = 2(l + w)

p = 2(l + 0.5l - 1.5).

P = 3l - 3.

The problem asks for two expressions, hence we wrote one expression for the perimeter as a function of the width and another as a function of the length.

The height of the the building is 95.5 feet.

As per the given data:

A building casts a 103-foot shadow.

At the same time, a 32-foot flagpole casts a 34.5-foot shadow.

Diagrams of both the building and flagpole are attached at the end of the solution.

Here we have to determine the height of the building.

From the above figure, in Δ ABC, AB shows the height of the building and BC shows its shadow length. In ΔDEF, DE shows the height of the flagpole and EF shows its shadow length.

In ΔABC

\($ \tan \theta=\frac{A B}{B C} \\\)

\($& \tan \theta=\frac{A B}{103}\)

In ΔDEF

\($& \tan \theta=\frac{D E}{E F} \\\)

\($\tan \theta=\frac{32}{34.5}\)

At the same time, the angle of elevation of the sun is the same at all the places.

Therefore

\($& \tan \theta=\tan \theta \\\)

\($& \frac{A B}{103}=\frac{32}{34.5} \\\)

\($& AB = \frac{32 \times 103}{34.5} \\\)

A B = 95.5 foot

Therefore, the height of the building will be 95.5 feet.

1. The solution for the equation is -16t² + 48t < 0

2. The interval notation for the equation is (0, 3)

Given,

The height of the building = 280 feet

A ball is thrown straight up from the top of the building.

The initial velocity of the ball = 48 feet/second

The height of the object is modeled by, s(t) = -16t² + 48t + 280

1. Solution for the equation:

s(t) < 280

So,

-16t² + 48t + 280 < 280

Add -280 to both sides

ie, -16t² + 48t + 280 - 280 < 280 - 280

We get,

-16t² + 48t < 0

2. Now find the interval notation for the equation:

-16t² + 48t < 0

Here, 48/16 = 3

So,

-16t (t - 3) < 0

We can use the formula for the sum of an arithmetic series to find the value of U infinity i = 1 Ai for each given set Ai:

(a) Ai = {i, i + 1, i + 2,...}

The sum of this arithmetic series is:

U infinity i = i + (i + 1) + (i + 2) + ...

            = i + (i + 1) + (i + 2) + ... + (i + n) - (1 + 2 + 3 + ... + n)

 where n is any positive integer.

The sum of the first n positive integers is given by the formula:

1 + 2 + 3 + ... + n = n(n+1)/2

Substituting this into the expression for U infinity i, we get:

U infinity i = i + (i + 1) + (i + 2) + ... + (i + n) - n(n+1)/2

Simplifying, we get:

U infinity i = (n+1)i + n(n+1)/2 - n(n+1)/2

            = (n+1)i

Taking the limit as n approaches infinity, we get:

U infinity i = lim (n approaches infinity) (n+1)i = infinity

Therefore, U infinity i = 1 Ai for the set Ai = {i, i + 1, i + 2,...} is infinity.

(b) Ai = {0, i}

The sum of this arithmetic series is:

U infinity i = 0 + 1 + 2 + ... + i-1 + i

Using the formula for the sum of an arithmetic series, we get:

U infinity i = [i(i+1)]/2

Taking the limit as i approaches infinity, we get:

U infinity i = lim (i approaches infinity) [i(i+1)]/2 = infinity

Therefore, U infinity i = 1 Ai for the set Ai = {0, i} is infinity.

(c) Ai = (0, i)

The sum of this set is:

U infinity i = integral from 0 to i dx

Evaluating the integral, we get:

U infinity i = [x] from 0 to i = i

Therefore, U infinity i = 1 Ai for the set Ai = (0, i) is i.

(d) Ai = (i, infinity)

The sum of this set is:

U infinity i = integral from i to infinity dx

Taking the limit as the upper limit of integration approaches infinity, we get:

U infinity i = lim (b approaches infinity) integral from i to b dx

            = lim (b approaches infinity) (b - i)

            = infinity

Therefore, U infinity i = 1 Ai for the set Ai = (i, infinity) is infinity.
