Answer:

-52

Step-by-step explanation:

If x = -2 and y = 6, then we can substitute those values into the expression:

5(2 x - 4) - 2y = 5(2(-2) - 4) - 2(6)

= 5(-4 - 4) - 2(6)

= 5(-8) - 2(6)

= -40 - 12

= -52

So, the value of the expression 5(2 x - 4) - 2y when x = -2 and y = 6 is -52.

Rachel bought a total of 124 pencils.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

To find the total number of colored pencils Rachel bought, you can multiply the number of packs she bought by the number of pencils in each pack. Since she bought 15 packs of colored pencils with four pencils in each pack, the expression would be:

15 packs × 4 pencils/pack = 60 pencils

To find the total number of glitter pencils Rachel bought, you can use the same process. Since she bought 32 packs of glitter pencils with two pencils in each pack, the expression would be:

32 packs × 2 pencils/pack = 64 pencils

To find the total number of pencils Rachel bought in total, you would add the number of colored pencils to the number of glitter pencils. The expression would be:

60 pencils + 64 pencils = 124 pencils

Hence, she bought a total of 124 pencils.

Answer:

6 hours

Step-by-step explanation:

Given that:

Time taken by Larry = 9 hours

Time taken by Sarah = 18 hours

Rate:

Larry, a = 1/9

Sarah, s = 1/18

Time taken working together = x

Rate working together = 1 /x

Therefore,

Larry's rate + Sarah's rate = working together rate

1/9 + 1/18 = 1/x

(2 + 1) / 18 = 1/x

3 /18 = 1/x

Cross multiply

3x = 18

3x/3 = 18/3

x = 6

Hence, if they work together, it will take 6 hours

While a common rule of thumb is to have a minimum sample size of 100 for continuous data to be statistically significant, the actual appropriate sample size may vary depending on the specific study design and research question. Option(D)

In statistics, the term "statistical significance" refers to whether an observed effect or relationship in the data is likely to be real and not just due to random chance. To determine statistical significance, we often perform hypothesis testing.

The sample size is a crucial factor in hypothesis testing. A larger sample size generally provides more reliable and precise estimates of population parameters and increases the statistical power of the test. With a larger sample size, even smaller effects or differences between groups can become statistically significant.

While there is no hard and fast rule for the minimum sample size to achieve statistical significance, a common guideline is to aim for at least 30 samples. This guideline is often used in the context of the Central Limit Theorem, which states that the sampling distribution of the sample mean becomes approximately normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

In practice, the appropriate sample size depends on various factors, including the nature of the data, the effect size being studied, the desired level of confidence, and the statistical test used. Researchers often conduct sample size calculations based on these factors before conducting their studies to ensure they have an adequate sample size to achieve meaningful results and detect significant effects if they exist.

To show that the functions f and g are linearly independent, we need to prove that no nontrivial linear combination of f and g equals the zero function.

Suppose there exist constants a and b (not both zero) such that a f(x) + b g(x) = 0 for all x in [0, 1]. To show that f and g are linearly independent, we will demonstrate that a = 0 and b = 0 are the only possible values.

Considering the equation a f(x) + b g(x) = 0, we evaluate it at x = 0:

a*f(0) + b*g(0) = a*1 + b*0 = a = 0.

Now, we differentiate both sides of the equation with respect to x:

a*f'(x) + b*g'(x) = 0.

Again, evaluating this equation at x = 0, we have:

a*f'(0) + b*g'(0) = a*0 + b*1 = b = 0.

Since both a and b equal 0, we conclude that the only linear combination of f and g that yields the zero function is the trivial combination. Hence, f and g are linearly independent on the interval [0, 1].

I THINK IT'S THIS ANSWER Axis of symmetry: x = 0.5; Vertex: (0.5, –1); f(x) = x2 – x – 1

Step-by-step explanation:

Answer:

The answer to your question is the third choice.

Step-by-step explanation:

The axis of symmetry is the dotted red line which is located in x = 1/2

The Vertex is the lowest point of the parabola which is (1/2, -1)

The equation of the function is:

                       (x - h)² = 4p(y - k)

-Substitution

                       (x - 1/2)² = 4p(y + 1)

-We can not know the value of p

                       x² - x + 1/4 = y + 1

Discarding choices, there are two possible answer, the second and the third choices, but because of the Vertex (0.5, -1), i think the right answer is the third choice.

The Natural Unemployment Rate based on the information is 5%.

The natural rate of unemployment is the lowest unemployment rate when inflation is stable, or the unemployment rate when inflation is not accelerating. The natural rate of unemployment (NAIRU) is the rate of unemployment caused by all factors other than changes in aggregate demand. Potential GDP estimates are based on the long-term natural rate.

The unemployment rate is the proportion of the total labor force that is unemployed but actively looking for work and willing to work. Cyclical unemployment is associated with an industry's business cycle. It is a direct result of a drop in consumer demand, which has resulted in a drop in labor demand. If cyclical unemployment rises, it indicates that the economy is slowing, which is not good.

Cyclical unemployment occurs when labor forces are reduced as a result of business cycles or economic fluctuations. If you are cyclically unemployed, it means that your employer has laid you off to save money during a period of slow business.

In this case, the unemployment will be:

= Actual unemployment rate - Cyclical unemployment rate

Answer:

The answer is D 11/3

Step-by-step explanation:

Sally's conclusion that high school GPA is an excellent and useful predictor of performance ratings at work is not entirely supported by the correlation coefficient of 0.09 with a significance level of p<.01.

Although a significant correlation suggests a positive association between high school GPA and performance ratings, the strength of the relationship is weak. The practical significance of such a weak correlation may be limited in real-world scenarios where multiple factors can influence job performance.

It is also important to note that correlation does not imply causation.

Therefore, even if high school GPA is significantly correlated with performance ratings at work, it does not necessarily mean that high school GPA is a causative factor in better job performance. Other variables such as work experience, motivation, and personality may also contribute to predicting job performance, and their effects should also be taken into account when assessing the usefulness of high school GPA as a predictor.

The number of

Single scoop cones = s = 9

Double scoop cones = d = 6

Step-by-step explanation :

Let t he number of

Single scoop cones = s

Double scoop cones = d

A single-scoop cone was $3 and a double-scoop cone was $5. The coach bought 15 cones and paid $57.

The system of equation

= s + d = 15.. Equation 1

s = 15 - d

3s + 5d = 57.... Equation 2

We substitute 15 - d for s

3(15 - d) + 5d = 57

45 - 3d + 5d = 57

Collect like terms

- 3d + 5d = 57 - 45

2d = 12

d = 12/2

d = 6

Solving for s

s = 15 - d

s = 15 - 6

s = 9

Therefore,

The number of

Single scoop cones = s = 9

Double scoop cones = d = 6

The distance AD is 49 miles.

As per the given values of speed and time, we will calculate the distance AC. Firstly equalising the units.

As per the known fact, 60 minutes = 1 hour

30 minutes = (1/60)×30

30 minutes = 0.5 hour

Now, speed, distance and time are related as -

Speed = distance ÷ time

Distance = speed × time

Distance = 62 × 0.5

Distance = 31 miles

So, AC = 31 miles and BC = 25 miles.

Therefore, AB = AC - BC

AB = 31 - 25

AB = 6 miles

The distance AD = AC + CD

AD = 31 + 3 × AB

AD = 31 + 3 × 6

AD = 31 + 18

AD = 49 miles

Therefore, the distance between AD is 49 miles.
