which of the following is an equation of the line that is parallel to the x axis and contains (-4,2)

Let x is average for rest of seven test. Then average for remaining test is x= 2.27

The middle number, which is obtained by dividing the sum of all the numbers by the variety of numbers, is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.

The middle point of the set of values is the mean. It represents the mean of the data set's values. In statistics, the centre number, also known as the mean, is referred to as the average.

We want the TOTAL average to equal 94

4/9 of the 5 scores have an average of 178

Let x = average of the 5 remaining test, which is worth 5/9 of the total average.

We get: 94 = (4/9)(178) + (5/59)(x)

94=712/9+59x/9

846=712+59x

846-712=59x

134=59x

134/59=x

Solve: x = 2.27

in the athletics team, tall members tend to win three times as many medals as short members.20 number of medals have been won by short athletes.

This question can be solved by using the ratio method. Since tall athletes are said to win three times as many medals as short athletes, this means that the ratio of tall athletes' medals to short athletes' medals is 3:1. We can use this ratio to calculate how many medals have been won by short athletes. Since the team has won a total of 60 medals, we can divide this number by 4 (the total number of medals in the ratio) to get 15. We then multiply 15 by the ratio of short athletes' medals (1) to get 15 medals. This means that short athletes have won 20 medals, since 15 multiplied by 3 is 45, leaving 60-45=15 medals for the short athletes. Thus, 20 medals have been won by short athletes.

The orientation factor in a chemical reaction relates the frequency factor to the collision factor and depends on the extent of complexity of the reactants in a reaction.

Does the orientation factor depend on temperature?

The direction of the collision between the chlorine atoms and the ozone determines the pace of reaction; if the direction is incorrect, no reaction takes place. The right orientation will allow for response. The direction of collisions is independent of temperature.

According to the Collision Theory, molecules must collide with sufficient activation energy to break and re-form existing bonds, as well as with favorable spatial orientation, in order for a chemical reaction to occur.

The value of x is 27 in the given figure.

An angle is formed when two straight lines or rays meet at a common endpoint.

We need to find the value of x.

The given two angles are (4x+7) and 5(x-4).

The two angles are opposite angles so the two angles are equal.

Let us equate 4(x+7) and 5(x-4).

4x+7=5(x-4).

Apply distributive property on RHS

4x+7=5x-20

4x-5x=-20-7

-x=-27

Multiply both sides by minus

The unit rate of the graph that represents the proportional relationship is $12.5, which is below $13 per week. Therefore, Louis made the correct statement.

The graph of a proportional relationship is typically a straight line that runs through the point of origin (0, 0).

The slope of the graph gives the unit rate, which is calculated as m = y/x.

Given the graph that shows the proportional relationship between the number of weeks and the amount spent on coffee, we can use one point on the line, (4, 50) to find the unit rate, which will given us how much is spent per week.

Therefore:

Slope/unit rate or amount spent per week = y/x = 50/4 = $12.5.

Based on this, we can state that Louis is correct by saying Janie has not met her goal, because $12.5 per week is below the target of $13 each week.

Two two numbers whose difference is 88 and whose product is a minimum are -44 and 44.

Let the numbers be x and y where x is larger value and y is smaller number.

According to ques,

x - y =88

and we need to make product of numbers i.e 'xy' minimum.

So we can take x = 88 + y ------(2)

substituting value of x in xy, we get

(88 + y) (y) = y² + 88y ------(1) to make it minimum we need to equate its derivative equal to zero.

derivative of  (1) is 2y + 88

Equating it to zero, we get

2y + 88 = 0

subtracting 88 from both sides, we get

2y = -88

Dividing 2 from both sides, we get

y = -44 ------(3)

Substituting value of y from (3) in (2), we get

x = 88 - 44

x = 44

So, we get value of x as 44 and y as -44 to get their product as minimum.

Answer:

C) Infinite (More than one)

Step-by-step explanation:

A 95% confidence interval with a 4% margin of error suggests that your statistic will be 95% of the time within 4 percentage points of the true population value.

A survey, may reveal that the 98% confidence interval is between 4.88 and 5.26. So, if the poll is repeated using the same methods, the true population parameter (parameter vs. statistic) will fall 98% of the time within the interval estimates (i.e. between 4.88 and 5.26).

The formal definition, on the other hand, includes a little more information. The margin of error in a confidence interval is defined as the range of values below and above the sample statistic. The confidence interval is a tool for demonstrating the level of uncertainty associated with a certain statistic (i.e. from a poll or survey).

In 2012, a Gallup poll (incorrectly) predicted that Romney would win the election, with Romney polling at 49% and Obama polling at 48%. The declared level of confidence was 95%, with a margin of error of 2. We can conclude that the results were computed to be 95% accurate within 2 percentage points.
