The prevalence rate of flu cases requiring hospitalization thus far in 2018 is:

= 0.13%

Step-by-step explanation:

a) Data and Calculations:

Population of Portland, ME = 70,000

Number of flu cases requiring hospitalization on February 1st, 2018 = 43

Number of flu cases requiring hospitalization on July 4th, 2018 = 90

The prevalence rate of flu cases requiring hospitalization thus far in 2018 = 90/70,000 * 100 = 0.13%

b) The prevalence rate represents the proportion of the population of Portland, ME, who have the flu at the time that the Maine Public Health Department reported the number of flu cases requiring hospitalization on July 4th, 2018.

Answer: 5 feet 6 inches.

Step-by-step explanation:

12 inches = 1 foot

We can divided 66 by 12 to find how tall Joan is in feet.

66 ÷ 12 = 5.5

The term "0.5" means half, and there are 12 inches in a foot. So half of a foot would mean 6, so Joan's height would be 5 feet and 6 inches.

Joan is 66 inches tall, then the height of Joan in feet will be equal to 5.5 feet.

Multiplying or dividing by a numeric number, or more specifically, a correction factor, is a procedure comprising several steps known as conversion.

Rounding and choosing the appropriate number of significant digits may also be necessary steps in the procedure.

As per the given information in the question,

The given height of Joan = 66 inches

So, let's perform unit conversion,

1 foot  = 12 inches, so,

x foot = 66 inches

Use cross-multiplication,

12x = 66 × 1

x = 66/12

x = 5.5 feet.

y = -2(1) - 1

y = -2 - 1

y = -3

(1, -3)

Answer:

y = 2x² - 72 = 0

Step-by-step explanation:

2(x - 6)(x + 6) = 0

2(x² - 36) = 0

2x² - 72 = 0

The quadratic equation with roots 6 and -6 and a leading coefficient of 2 is 2x² - 72 = 0 represents the quadratic equation.

A quadratic equation with roots at 6 and -6 can be written in factored form as:

(x - 6)(x + 6) = 0

To find the quadratic equation with the leading coefficient of 2, we multiply both sides of the equation by 2:

2(x - 6)(x + 6) = 0

Expanding the equation:

2(x² - 36) = 0

Distributing the 2:

2x² - 72 = 0

Therefore, the quadratic equation with roots 6 and -6 and a leading coefficient of 2 is:

2x² - 72 = 0

Answer:

[tex]y = 4x[/tex]

Step-by-step explanation:

Given

[tex]x = 44[/tex]

[tex]y = 176[/tex]

Required

Determine the relationship between x and y

First, we calculate the unit rate, using:

[tex]y = kx[/tex]

Where k is the unit rate.

Substitute 176 for y and 44 for y

[tex]176 = k * 44[/tex]

Divide both sides by 44

[tex]\frac{176}{44} = \frac{44*k}{44}[/tex]

[tex]\frac{176}{44} = k[/tex]

[tex]4 = k[/tex]

[tex]k = 4[/tex]

Substitute 4 for k in [tex]y = kx[/tex]

[tex]y = 4x[/tex]

Hence, the relationship between x and y is: [tex]y = 4x[/tex]

Answer:

120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

Given the following expression:

To determine an estimate for each expression:

A fraction can be defined as a numerical quantity that is not expressed as a whole number. Therefore, a fraction is simply a part of a whole number.

Generally, a fraction comprises two (2) main parts and these include:

In this exercise, we would simplify and estimate the given expressions as follows:

Note: An estimate simply means an approximate value.

a. [tex]\frac{1}{8} + \frac{2}{5}=\frac{5+16}{40}=\frac{21}{40}[/tex]

For the estimate:

[tex]\frac{1}{8} + \frac{2}{5}=\frac{1}{2}[/tex]

b. [tex]\frac{13}{14} -\frac{1}{10}=\frac{130-14}{140} =\frac{116}{140} =0.83[/tex]

For the estimate:

0.83 ≈ 1

c. [tex]\frac{1}{12} + \frac{1}{20}=\frac{5-3}{60} =\frac{2}{60} =0.03[/tex]

For the estimate:

0.03 ≈ 0

Answer:

It will take 30.48 for the money in his account to double.

Step-by-step explanation:

Interest compounded anually:

With an investment of P, the amount compounded annualy after t years that you will have is given by:

[tex]A(t) = P(1+r)^{t}[/tex]

In which r is the interest rate, as a decimal.

Ren sets aside $1,000 into an online savings account with an annual interest rate of 2.3%

This means that [tex]P = 1000, r = 0.023[/tex]. So

[tex]A(t) = P(1+r)^{t}[/tex]

[tex]A(t) = 1000(1+0.023)^{t}[/tex]

[tex]A(t) = 1000(1.023)^{t}[/tex]

How long will it take for the money in his account to double?

This is t for which A(t) = 1000*2 = 2000. So

[tex]A(t) = 1000(1.023)^{t}[/tex]

[tex]2000 = 1000(1.023)^{t}[/tex]

[tex](1.023)^{t} = \frac{2000}{1000}[/tex]

[tex](1.023)^{t} = 2[/tex]

[tex]\log{(1.023)^{t}} = \log{2}[/tex]

[tex]t\log{1.023} = \log{2}[/tex]

[tex]t = \frac{\log{2}}{\log{1.023}}[/tex]

[tex]t = 30.48[/tex]

It will take 30.48 for the money in his account to double.

Answer:

The distance between (5, -8) and (5,2) is: d = 10 units

Step-by-step explanation:

Note: I will solve the first question as the procedure solution for the remaining questions is exactly the same.

Given the points

Determining the distance between (5, -8) and (5,2)

[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

substitute (x₁, y₁) = (2, 3) and (x₂, y₂) = (2, -5)

   [tex]=\sqrt{\left(5-5\right)^2+\left(2-\left(-8\right)\right)^2}[/tex]

   [tex]=\sqrt{\left(5-5\right)^2+\left(2+8\right)^2}[/tex]

   [tex]=\sqrt{0+10^2}[/tex]

   [tex]=\sqrt{10^2}[/tex]

   [tex]=10[/tex]  units

Therefore, the distance between (5, -8) and (5,2) is: d = 10 units
