\( \frac{3}{8} + \frac{1}{8} = \frac{4}{8} \)

4/8 is half. so simplest form would be

\( \frac{1}{2} \)

Answer:

1/2 minutes

Step-by-step explanation:

you add the two fractions together and because they have a common denominator you just add across.

1/8+3/8=4/8

now we simplify

the numerator and denominator can both be divided by 4.

4÷4=1

8÷4=2

1/2

According to the information, the number of the image would be 17/100 or 0.17

To express this number in fraction and decimal we must take into account different aspects. First of all we must consider the reference numbers that are on the number line.

On the other hand, we must count how many segments each unit of the line is divided into. In this case it is in 10. So to identify the number we can add a 0 to the denominator and take the numerator as an integer that would be 17. Then the fraction would remain:

In the case of the decimal we only have to carry out the division and we will obtain the decimal.

Answer:

a) 4x + 12 = 54

b) Long side = 16.5cm and Short side = 10.5cm

Step-by-step explanation:

→ Perimeter = All of the sides added together so,

x + 6 + x + 6 + x + x = 54

→ Simplify

4x + 12 = 54

→ Minus 12 from both sides to isolate 4x

4x = 42

→ Divide both sides by 4 to isolate x

The x- intercept of the equation is (13,0) and y-intercept of the equation is (0,-39/8) when the equation is 3x-8y=39.

Given that,

The equation is 3x-8y=39.

We have to find the x- intercept and y- intercept of the equation.

We know that,

x/a + y/b = 1 is the intercept form of the line's equation. One of the key types of line equations is this one. In this equation, the sign of the intercepts also enables us to determine where the line is in relation to the coordinate axes.

To find the x- intercept of the equation.

We have to take y as 0.

3x-8(0)=39

3x=39

x=39/3

x=13

To find the y- intercept of the equation.

We have to take x as 0.

3(0)-8y=39

-8y=39

x=-39/8

Therefore, The x- intercept of the equation is (13,0) and y-intercept of the equation is (0,-39/8) when the equation is 3x-8y=39.

Answer:

The test statistic for testing if the proportion of high-altitude vehicles exceeding the standard is greater than the proportion of low-altitude vehicles exceeding the standard is 3.234.

Step-by-step explanation:

We are given that in a random sample of 380 cars driven at low altitudes, 42 of them exceeded a standard of 10 grams of particulate pollution per gallon of fuel consumed.

In an independent random sample of 90 cars driven at high altitudes, 24 of them exceeded the standard.

Let \(p_1\) = population proportion of cars driven at high altitudes who exceeded a standard of 10 grams.

\(p_2\) = population proportion of cars driven at low altitudes who exceeded a standard of 10 grams.

So, Null Hypothesis, \(H_0\) : \(p_1\leq p_2\)      {means that the proportion of high-altitude vehicles exceeding the standard is smaller than or equal to the proportion of low-altitude vehicles exceeding the standard}

Alternate Hypothesis, \(H_A\) : \(p_1>p_2\)      {means that the proportion of high-altitude vehicles exceeding the standard is greater than the proportion of low-altitude vehicles exceeding the standard}

The test statistics that will be used here is Two-sample z-test statistics for proportions;

                             T.S.  =  \(\frac{(\hat p_1-\hat p_2)-(p_1-p_2)}{\sqrt{\frac{\hat p_1(1-\hat p_1)}{n_1}+\frac{\hat p_2(1-\hat p_2)}{n_2} } }\)  ~  N(0,1)

where, \(\hat p_1\) = sample proportion of cars driven at high altitudes who exceeded a standard of 10 grams = \(\frac{24}{90}\) = 0.27

\(\hat p_2\) = sample proportion of cars driven at low altitudes who exceeded a standard of 10 grams = \(\frac{42}{380}\) = 0.11

\(n_1\) = sample of cars driven at high altitudes = 90

\(n_2\) = sample of cars driven at low altitudes = 380

So, the test statistics =  \(\frac{(0.27-0.11)-(0)}{\sqrt{\frac{0.27(1-0.27)}{90}+\frac{0.11(1-0.11)}{380} } }\)      

                                   =  3.234

The value of z-test statistics is 3.234.

The difference between the means is approximately 0.533 times the mean Absolute deviation.

We first need to find the means of the two datasets using the double stem and leaf plots given:

Pizzeria A:

| 4 | 5 7 8 8 |

| 5 | 1 2 3 3 5 6 8 |

Mean: (4+5+5)/3 + (1+2+3+3+5+6+7+8)/8 = 4.67 + 4.125 = 8.795

Pizzeria B:

| 6 | 2 3 4 4 5 5 6 7 |

| 7 | 0 1 1 2 4 4 4 6 8 9 |

Mean: (6+7)/2 + (2+3+4+4+5+5+6+7)/8 + (0+1+1+2+4+4+4+6+8+9)/10 = 6.5 + 4.125 + 3.5 = 14.125

Next, we need to find the difference between the means:

14.125 - 8.795 = 5.33

To determine how many times the mean absolute deviation is approximately 10, we need to divide the difference between the means by the mean absolute deviation:

5.33/10 = 0.533

Therefore, the difference between the means is approximately 0.533 times the mean absolute deviation.

Simply count the number of red marbles in each sample and divide by the total number of marbles in the sample (16). Then, take the average of those proportions to estimate the proportion of red marbles in the jar as a whole

Based on the information provided, the best conclusion we can make is an estimate of the proportion of red marbles in the jar. We can use the four random samples of 16 marbles to calculate the proportion of red marbles in each sample, and then take the average of those proportions to estimate the overall proportion of red marbles in the jar.

It's important to note that this estimate may not be perfectly accurate, since the samples are small and may not perfectly represent the entire jar. However, it's a useful way to get an idea of how many red marbles are in the jar without having to count all of them.

Step-by-step explanation:

trust me and mark me brainliest

The compound inequality that represents the range of the actual weight of the object is 125.4 ≤ w ≤ 126.2.

Part A: The absolute value inequality that describes the range of the actual weight of the object is:

|w - 125.8| ≤ 0.4

Part B: To solve the absolute value inequality, we can break it down into two separate inequalities:

w - 125.8 ≤ 0.4 and - (w - 125.8) ≤ 0.4

Solving the first inequality:

w - 125.8 ≤ 0.4

Add 125.8 to both sides:

w ≤ 126.2

Solving the second inequality:

-(w - 125.8) ≤ 0.4

Multiply by -1 and distribute the negative sign:

-w + 125.8 ≤ 0.4

Subtract 125.8 from both sides:

-w ≤ -125.4

Divide by -1 (note that the inequality direction flips):

w ≥ 125.4

Combining the solutions, we have:

125.4 ≤ w ≤ 126.2

The object is 125.4 ≤ w ≤ 126.2.
