What equation to solve what problem?

A. The temperature at noon will be 6°F.

B. The thing that represents zero in this situation is when the temperature is neither raised nor dropped and it's at the initial stage.

Temperature is the measure of how hot or cold something is expressed in terms of one of several scales, which include Fahrenheit and Celsius. The direction in which heat energy will spontaneously flow is indicated by temperature.

A. From the information, by 6:00 A.M., the temperature had dropped 4 F, and then the temperature raised 10 F by noon.

The temperature at noon will be:

= -4°F + 10°F

= 6°F

The temperature at 0 simply means the initial temperature.

Answer:

P(X > 2.6) = 0.0475 = 4.75%

Step-by-step explanation:

Let X is the random variable that represents percent of childhood asthma prevalence.

We want to find out the probability that the  mean childhood asthma prevalence for the sample is greater than 2.6%

The z-score corresponding to 1.67 is 0.9525

P(X > 2.6) = 1 - 0.9525

P(X > 2.6) = 0.0475

P(X > 2.6) = 4.75%

Therefore, there is 4.75% probability that the mean childhood asthma prevalence for the sample is greater than 2.6%

How to use z-table?

Step 1:

In the z-table, find the two-digit number on the left side corresponding to your z-score. (e.g 1.6)

Step 2:

Then look up at the top of z-table to find the remaining decimal point in the range of 0.00 to 0.09. (e.g. if you are looking for 1.67 then go for 0.07 column)

Step 3:

Finally, find the corresponding probability from the z-table at the intersection of step 1 and step 2.

The expression that shows how many comic books Tessa has is 14t

From the question, we have the following parameters that can be used in our computation:

Tessa = t times as many as Joseph

Joseph = 14 comic books

These parameters means that

Tessa = t times Joseph

So, we have

Tessa = t * Joseph

Substitute the known values in the above equation, so, we have the following representation

Tessa = t * 14

Evaluate

Tessa = 14t

Hence, the expression is 14t

Answer:

-27

(negative number)

Step-by-step explanation:

-b/2a = -(-16)/2(1) = 16/2 = 8

                       x       +          8

                 x   x^2                8x

                 +

                 8    8x                64

So we got 64, but 64 is not 37 so we need to change that by subtracting 27 from it.

64 - 27 = 37

So the final answer (in vertex form) is:

(x+8)^2 - 27

(-27) is the number being added

The value of angle RPQ in the circle is 115 degrees.

The intersecting chords theorem, also known as the chord theorem, is an elementary geometry statement that describes a relationship between the four line segments formed by two intersecting chords within a circle.

If two chords intersect inside a circle, then the measure of the angle formed is one-half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Therefore,

∠RPQ = 1  / 2 (arc angle RQ + arc angle SA)

arc angle RQ = 175 degrees

arc angle SA = 55 degrees

Hence,

∠RPQ  = 1 / 2 (175 + 55)

∠RPQ  = 1 / 2 (230)

∠RPQ  = 115 degrees.

The angle is 115°.

The simple interest on 1600 with a 6% interest rate for 2 years is $192.

The simple interest simply means the method that's used to calculate the interest that's charged on a loan or money given out.

In this situation, we want to calculate the simple interest on 1600 with a 6% interest rate for 2 years. This will be calculated thus:

Simple interest = Principal × Rate × Interest

Simple interest = $1600 × 6% × 2

Simple interest = $1600 × 0.06 × 2

Simple interest = $192

Step-by-step explanation:

The domain of a function is the set of all possible input values that the function can take without breaking. In the case of f(x) = log(5x+10) + 3, the domain is all real numbers x such that 5x+10 is greater than 0. This is because the log function is not defined for values less than or equal to 0.

To find the domain of f(x), we need to solve the inequality 5x+10 > 0. We can do this by subtracting 10 from both sides of the inequality, which gives us 5x > -10. Dividing both sides by 5 gives us x > -2. Therefore, the domain of f(x) = log(5x+10) + 3 is all real numbers x such that x > -2.

9                    4

6                    2

0                    -2

-3                   -4

A function that relates the distance (d) traveled to the time (t) is d = 120t.

A graph of the function is shown in the image attached below and it is a linear function.

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

Next, we would use the given function in slope-intercept to complete the table of values as follows;

When y = 9, the value of x is given by:

y = 3x/2 + 3

9 = 3x/2 + 3

3x/2 = 9 - 3

3x/2 = 6

3x = 12

x = 12/3

x = 4.

When y = 6, the value of x is given by:

y = 3x/2 + 3

6 = 3x/2 + 3

3x/2 = 6 - 3

3x/2 = 3

3x = 6

x = 6/3

x = 2.

When y = 0, the value of x is given by:

y = 3x/2 + 3

0 = 3x/2 + 3

3x/2 = -3

3x = -6

x = -6/3

x = -2.

When y = -3, the value of x is given by:

y = 3x/2 + 3

-3 = 3x/2 + 3

3x/2 = -3 - 3

3x/2 = -6

3x = -12

x = -12/3

x = -4.

Mathematically, a constant of proportionality (speed) for this train's journey (distance) can be represented with the following mathematical expression:

d = kt

Where:

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = d/t

Constant of proportionality (k) = 360/3

Constant of proportionality (k) = 120

Therefore, the required function that relates the distance (d) and time (t) is given by;

d = kt

d = 120t
