Write 3 quadratic equations that are NOT
equivalent, each forming a graph with vertex (-2, 3)

Step-by-step explanation:

per the laws of intersecting lines the angles on one side of any of the lines must be the same as the angles on the other side of that line - just left-right mirrored.

for that reason, CGE = DGF.

also to remember : the sum of all angles around a point on one side of a line is always 180° (because they represent a half-circle with that point being the center). in other words, these angles are supplementary (together 180°).

therefore,

180 = 62 + 32 + DGF

DGF = CGE = 180 - 62 - 32 = 86°

When selecting the appropriate number of treatment conditions, it is essential to consider factors such as resources, research complexity, and confounding variables.

Having conditions that are proportional to each other means that the level or intensity of each condition varies in direct proportion to the others, such that if one condition is increased or decreased, the others are also adjusted in a corresponding manner.

When choosing the appropriate number of treatment conditions for an experiment, there are several issues to consider. One of these is the ability to distinguish differences between treatment conditions.

Having conditions that are proportional to each other means that the differences between treatment conditions are consistent across all levels of the independent variable. In other words, if the independent variable increases by a certain amount, the difference between the treatment conditions remains constant. This can be important for ensuring that the treatment effects are interpretable and generalizable to other populations.

Answer:

x = 10

Step-by-step explanation:

1. Because this is a right angle (an angle with 90°), 54 + 3x + 6 = 90.

2. (Solving equation above)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 60 from both sides.

Step 3: Divide both sides by 3.

Step 4: Check if solution is correct.

Therefore, x = 10.

The statement "the interquartile range is least influenced by an outlying value in the data set" is true.

The range is simply the difference between the maximum and minimum values in a data set.

The variance is a measure of the spread of a data set, and is calculated by finding the average of the squared differences between each data point and the mean of the data set.

The interquartile range, on the other hand, is a measure of the spread of the middle 50% of the data set. It is calculated by finding the difference between the upper quartile and the lower quartile.

Because the interquartile range only takes into account the middle 50% of the data, it is less influenced by outliers than the range and variance. This is because outliers can greatly impact the range and variance, but have little effect on the interquartile range.

In conclusion, the interquartile range is a more robust measure of spread for a data set, as it is less influenced by outliers.

Answer:   infinitely many solutions

Step-by-step explanation:

The system is only 1 line.  So it must be that there are 2 equations that are actually the same so they intersect infinitely many times.

The drink contains 56mg of the vitamin while RDA is only 40mg.

The SI unit of mass, the kilogramme, is 1000,000,000 times larger than the milligramme (mg), which is a unit of mass. Using a lowercase m and lowercase g, a milligramme is abbreviated as mg.

There are 1000 milligrammes in a gramme, hence the use of the prefix milli to denote the thousandth.

There are 10-6 kilogrammes in a milligramme. When describing drug doses, milligrammes are frequently used.

We have to count 140​% of the RDA to find the how much vitamins its contains.

Here, RDA = 40mg

140​% × 40

140/100 × 40

1.4  × 40

56mg

Thus, the drink contains 56mg of the vitamin while RDA is only 40mg.

b. The probability of winning is approximately 0.14%.

c. If you win, your net profit would be $319.45.

d. Therefore, the expected value is -$0.21, which means that on average, you can expect to lose $0.21 per ticket.

a. In a Pick 3 lottery game, there are 10 digits (0-9) and you are selecting a sequence of three digits. Therefore, the total number of different selections possible can be calculated using the formula for permutations, which is:

10P₃ = 10!/7! = 10 x 9 x 8 = 720

b. The probability of winning is the number of winning outcomes divided by the total number of possible outcomes. Since there is only one winning sequence of three digits, the probability of winning is:

1/720 = 0.0014

c. If you win, your net profit would be the prize amount ($320.68) minus the cost of the ticket ($1.23), which is:

$320.68 - $1.23 = $319.45

d. The expected value is the sum of the products of each outcome and its probability. In this case, the expected value can be calculated as:

(1/720) x ($320.68) + (719/720) x (-$1.23) = -$0.21

This negative expected value indicates that the lottery is not a good investment as the cost of playing exceeds the expected payout.

Step-by-step explanation:

Answer:

  GCF = 6; sum = 6(1 +3)

Step-by-step explanation:

You want the greatest common factor of 6 and 18.

The greatest common factor is the largest factor common to both numbers. Here, we can factor the numbers as ...

  6 = 6·1

  18 = 6·3

The factor 6 is common to both numbers. (Other numbers, such as 1, 2, and 3 are also common factors, but 6 is the largest.)

The GCF is 6.

In terms of the GCF, the sum can be written ...

  6 +18 = 6(1 +3)

__

Additional comment

If the smaller number is not a factor of the larger, then the next value to check is the difference between the larger and smaller.

Euclid's algorithm tells you the remainder from division of the larger by the smaller will be zero when the divisor is the GCF. Otherwise, the remainder can be used to replace the larger number for trying again.

Here, 18/6 = 3 r 0, so 6 is the GCF.

The value of expression  (v, w, + 3u) is 11, so correct option is C.

Given that (u, v) = 3 and (v, w) = 2.

To find: The value of (v, w, + 3u)

This formula shows how multiplication distributes over addition. It means that when you multiply a number by the sum of two other numbers, it is the same as multiplying the number individually by each of the two numbers and then adding the products together.

We have to apply the formula of distributivity of multiplication over addition:

(a + b) c = ac + bc

We know that 3u = u + u + u,

so substituting in (v, w, + 3u),

we get(v, w, + 3u) = (v, w) + (u + u + u)

Now, substituting the given values of (u, v) = 3 and (v, w) = 2

in the above equation(v, w, + 3u) = (2) + (3 + 3 + 3) = 2 + 9 = 11

Therefore, the value of (v, w, + 3u) is 11.

Hence, the correct option is (c) 11.

NOTE: We should always remember the formula of distributivity of multiplication over addition: (a + b) c = ac + bc.

Fewer families with kids under 18 now have dinner together seven nights a week

Given,

Let p represent the percentage of households with kids under 18 that have supper together every night.

So, Null Hypothesis, : p 38%    (meaning that more or the same number of families with children under the age of 18 now have dinner together seven nights a week.)

Alternate Hypothesis, : p < 38%     {means that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has​ decreased}

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

T.S.  =    ~  N(0,1)

Where,

p  = sample proportion of families = 403/1122 = 0.36

n = sample of adults with children under the age of 18 = 1122

So,

The test statistics =     -1.32

The value of z-statistics is -1.32.

Also, the P-value of the test statistics is given by;

 P-value = P(Z < -1.32) = 1 - P(Z  1.32)

= 1 - 0.9066 = 0.0934

We have enough data to reject our null hypothesis since the test statistics will fall in the rejection region because the P-value for our test statistics is less than the level of significance, which in this case is 0.0934 <  0.10.

As a result, we draw the conclusion that fewer families with children under the age of 18 now have supper together seven nights a week.

Step-by-step explanation:

The percent error of masdion estimate is 8%.

As we know that some degree of error is often associated with measurements. Percent error is used to determine how close the value is to the accepted answer.

We know,

\(\frac{Error}{actual value} = \frac{Percent}{100}\)                                               equation 1

Total number of jelly beans in a jar estimated by madison = 918

The actual number of jelly beans = 850

Error = Estimated jelly beans - Actual number of jelly beans

Error = 918 - 850

Error = 68

Substitute value of error and actual value in equation 1 , we will get

( 68 / 850 ) = ( percent error / 100 )

0.08 × 100 = percent error

percent error = 8 %

Thus, 8% was the percent error of masdion estimate.
