answer:
c = 7.6 kilometers
step-by-step explanation:
you can use the pythagorean theorem for this since this is a right triangleknow the formula: a^2 + b^2 = c^2now plug in what we know, also remember:
a = legb = the other legc = hypotenusea^2 + b^2 = c^2
3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
c = 7.6157
rounded: c = 7.6 kilometers

One of Carla's friends suggests that she survey only eighth-graders because they are the
oldest and probably know more about the election than younger students. Do you think
this suggestion creates a random sample? Explain.
Answer:
This example is not a random example due to the fact that it is only questioning the eighth-graders. Random sample means that the sample is chosen simply randomly and everyone has an equal opportunity to be apart of the sampling.

Which ordered pair can be plotted together with these four points, so that the resulting graph still represents a function?
O (2, -1) O (-5,2) O (2,-5) (-2,5)
(-5, 2) is the only point which we plot in given graph then it still represent a function.
What is Function?A function is a special type of relation in which each and every element of set A have a unique image in its codomain set B.
Here, Given points on graph
{(-4, 2), (-2, -3), (2, 3), (3, -1)}
2 and -2 are already available in given ordered pair.
so only (-5, 2) is the only option which satisfies the definition of function.
Thus, (-5, 2) is the only point which we plot in given graph then it still represent a function.

Triangle:
Procedure:
The interior angles of a triangle add up to 180°. As we know two angles, we can get the third as follows:
\(m\angle L+m\angle K+m\angle J=180\)Isolating for m∠J
\(m\angle J=180-m\angle L-m\angle K\)Replacing the values given:
\(m\angle J=180-41-117\)\(m\angle J=22\)Then using the trigonometric functions, we can get the sides.
\(\frac{\sin (41)}{14}=\frac{\sin (117)}{JL}\)\(JL=\frac{\sin(117)}{\frac{\sin(41)}{14}}\)\(JL\approx19.01\)\(\frac{\sin(41)}{14}=\frac{\sin (22)}{KL}\)\(KL=\frac{\sin (22)}{\frac{\sin(41)}{14}}\)\(KL\approx7.99\)Answer:

Why has government set maximum price on fuel in south africa
The South African government has set a maximum price on fuel to protect consumers from price hikes and to maintain economic stability.
Fuel is a crucial commodity in the country and affects the prices of goods and services. South Africa is a net importer of fuel and is heavily reliant on oil imports, which means that fluctuations in international oil prices can impact local fuel prices. By setting a maximum price, the government can ensure that fuel prices remain affordable and accessible for all South Africans, especially those who rely on it for their livelihoods.
The government also uses fuel taxes as a source of revenue, which is used to fund various public services. It is important to note that the maximum price is reviewed monthly and is adjusted based on various factors such as international oil prices, exchange rates, and local taxes.

Cross multiply 100 and 1, which makes 100. Then cross divide 100 by two, which makes 50.
Then check if 2% of 50 is 1, which is true.

C. The result of 3 peas with green pods a result is significantly low.
What is the probability?
The probability of an occurrence is a number used in science to describe how likely it is that the event will take place. In terms of percentage notation, it is expressed as a number between 0 and 1, or between 0% and 100%. The higher the likelihood, the more likely it is that the event will take place.
Here, we have
Given: Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods.
This is a binomial probability distribution problem.
Where n = 24 [groups of 24, total trials]
p = 0.75 [probability of success]
a) Mean = np =24×0.75 = 18
and std deviation =(np(1-p))1/2 = 2.1213
b) from a range rule of thumb; 2 std deviation values above and below the mean are significantly low AND significantly high
Hence significantly low value = mean -2×std deviation = 13.76 or lower values
Significantly high value =mean +2*std deviation = 22.24 or higher values
c) As 3 falls in significantly low values cause it is below 2 std deviations from the mean hence it is significantly low.

if a confidence interval is given from 43.85 up to 61.95 and the mean is known to be 52.90, what is the margin of error?
The margin of error can be calculated using the formula:
Margin of error = (upper limit of the confidence interval - lower limit of the confidence interval) / 2
In this case, a margin of error of 9.55 suggests that the sample mean is quite precise, since it's relatively close to the true population mean (which we know to be 52.90).
In this case, the lower limit of the confidence interval is 43.85 and the upper limit is 61.95.
Margin of error = (61.95 - 43.85) / 2
Margin of error = 9.55
Therefore, the margin of error is 9.55. This means that if the sample size were to be repeated, we would expect the sample mean to be within 9.55 units of the true population mean 95% of the time.
It's worth noting that the confidence interval provides a range of values within which we can be reasonably certain that the true population mean lies. The margin of error, on the other hand, gives us an indication of the precision of our estimate. However, if the margin of error were larger, this would indicate that our estimate is less precise and that we need a larger sample size to obtain a more accurate estimate of the population mean.

If two events are collectively exhaustive, what is the probability that both occur at the same time? a) 0
b) 0.50 c) 1.00 d) Cannot be determined
If two events are collectively exhaustive, then the probability that both occur at the same time is 0 .(option-a)
Tossing a coin is an illustration of two occurrences that are both mutually exhaustive and mutually exclusive. When we flip a coin, we can only obtain either a head (H) or a tail (T), never both (H) and (T). As the events are mutually exclusive in this situation, the probability of receiving both a head and a tail is equal to P(H and T) = 0, and the chance of getting either a head or a tail is equal to P(H or T) = 1 since the occurrences are mutually exhaustive.

Which is the equation of a line parallel to the line with the equation: y = −14x + 7
y = -4x - 7
y = 4x + 2
y = 14x − 12
y = −14x + 3
Answer:
y = −14x + 3
Step-by-step explanation:
Parallel lines have the same slope
The equation y = −14x + 7 is put in slope intercept form ( y = mx + b )
Where m = slope
-14 takes "m's" place meaning that the slope = -14
If parallel lines have the same slope than the equation of a line parallel to y = −14x + 7 must have a slope of -14
The only equation that has a slope of -14 is D
