The thermometer reading would be 73.48°C.

The boiling point of water is generally considered to be 100°C. According to the given information, the temperature of the liquid in the thermometer is 26.52°C lower than the boiling point of water. Therefore, to find the thermometer reading, we subtract 26.52 from 100.

100 - 26.52 = 73.48

Hence, the thermometer reading would be 73.48°C.

In this scenario, we are assuming that the thermometer is calibrated to measure temperature in Celsius. The boiling point of water at standard atmospheric pressure is 100°C, and the given information states that the liquid in the thermometer is 26.52°C lower than the boiling point.

By subtracting 26.52 from 100, we obtain a reading of 73.48°C.

Thermometers work by utilizing the principle that certain substances, such as mercury or alcohol, expand or contract with changes in temperature. The expansion or contraction is measured using a scale, which is marked with various temperature values.

In this case, the thermometer is calibrated in Celsius, so we refer to the Celsius scale. By subtracting 26.52 from 100, we find the temperature at which the liquid in the thermometer is settled, which is 73.48°C.

y = 1/2x + 5

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

When 2 lines are parallel, they have the same slope.

Step 1: Define variables

Random point (2, 6)

m = 1/2

y = 1/2x + b

Step 2: Find b

6 = 1/2(2) + b

6 = 1 + b

Step 3: Rewrite parallel linear equation

y = 1/2x + 5

Answer:b

Step-by-step explanation:

The area of circle S will be 50.24 mm². Then the correct option is A.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The radius of circle S is half the radius of circle L.

Let 'r₁' be the radius of circle S and 'r₂' be the radius of circle L. Then the equation is given as

r₁ = r₂ / 2

The radius of circle L is 8 millimeters. Then the radius of the circle S is calculated as,

r₁ = 8 / 2

r₁ = 4 mm

The area of the circle S is calculated as,

A = πr₁²

A = 3.14 x (4)²

A = 50.24 mm²

The range of the circle S is 4 mm. Then the region of the circle S will be 50.24 mm². Then the right choice is A.

Given that,

The circumference of the largest orange in a bag is \(9\dfrac{5}{8}\ \text{inches}\) and that of smallest orange is \(7\dfrac{13}{16}\ \text{inches}\).

Difference = largest orange - smallest orange

The piecwise function in the graph is:

Here we have a piecewise function and we want to write the equation for it.

First, we can see a part whose domain is -4 < x  ≤ 0

The y-intercept is  at y = 6, sothis line is:

y = ax + 6

And it also passes through the point (-2, 4), replacing these values:

4 = -2a + 6

4 - 6 = -2a

-2 = -2a

1 = a

Then the first part is:

y = x + 6  for -4 < x  ≤ 0

The second part is defined in the domain 0 < x ≤ 6, the y-intercept this time is 4, so:

y = bx + 4

To find the value of b we use the fact that this passes through (6, 6), replacing that:

6 = b6 + 4

6 - 4 = b6

2 = b6

2/6 = b

1/3 = b

This part is:

y = x/3 + 4   for 0 < x ≤ 6

The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.

Let y represent the population after x years.

Given that the growth rate is 4.5% per year and the current population is 1500.

Hence a = 1500, b = 100% + 4.5% = 104.5% = 1.045

y = 1500(1.045)ˣ

After 6 years:

y = 1500(1.045)⁶ = 1953

Answer:

0.97547

Step-by-step explanation:

Given That:

Mean (m) = 102

Standard deviation (σ) = 12

Sample size (n) = 63

Probability that sample mean would differ from Population mean by less than 3.4 watts

P(m - s < X < m + s)

P(102 - 3.4 < Z < 102 + 3.4)

Using the Z formula :

Zscore = (x - m) / (σ/√n)

x = 102 - 3.4 = 98.6 ; x = 102 + 3.4 = 105.4

Z = (98.6 - 102) / (12/√63) = −2.248888

P(Z < - 2.2488) = 0.012263 (Z probability calculator)

Z = (105.4 - 102) / (12/√63) = 2.2488886

P(Z < 2.2488) = 0.98774 (Z probability calculator)

Amplitude is the maximum displacement of a function on a graph.

Amplitude is the maximum displacement of a function on a graph. It refers to the maximum height or distance from the baseline of a wave or oscillation.

It is often used in physics and engineering to describe the strength or size of a signal, vibration, or wave. In simple terms, it can be thought of as the "peak-to-peak" distance of a waveform, or the height of the waveform above and below the baseline.

But the minimum displacement of a function on a graph would typically be referred to as the minimum value or the "valley" of the function.

Answer:

Using distributive property to solve \((x+12)8\) we get \(\mathbf{8x+96}\)

Step-by-step explanation:

We need to used distributive property to solve (x+12)8

The distributive property of multiplication or addition states that: \(a(b+c)=ab+ac\)

Using the property:

\((x+12)8\\=8x+8*12\\=8x+96\)

So, using distributive property to solve \((x+12)8\) we get \(\mathbf{8x+96}\)

Step-by-step explanation:

a. Given a positive test result, the probability that a random patient has the disease is called the positive predictive value (PPV). The PPV can be calculated using the following formula:

PPV = Sensitivity * Prevalence / (Sensitivity * Prevalence + (1 - Specificity) * (1 - Prevalence))

Plugging in the values given in the question, we get:

PPV = 0.92 * 0.01 / (0.92 * 0.01 + (1 - 0.93) * (1 - 0.01)) = 0.087

So, the probability that a random patient has the disease given a positive test result is 0.087 or 8.7%.

b. A tree diagram for a typical sample of patients with a positive test result would look something like this:

+-----------+-----------------+

| Test Result| Positive (TP + FP) |

+-----------+-----------------+

| | TP (Disease) |

| | 0.92 * 0.01 |

| | FP (No Disease)|

| | 0.08 * 0.99 |

+-----------+-----------------+

c. If the prevalence is lower, the proportion of positive test results due to false positives (FP) increases compared to true positives (TP). This is because the positive predictive value (PPV) decreases as the prevalence decreases, meaning that a larger proportion of positive test results are due to false positives. This is why the proportion in error is larger if the prevalence is lower.
