No.

Step-by-step explanation:

The ratio of the lengths of the vertical sides from A to B is 2/4 which equals 1/2.

The ratio of the lengths of the horizontal sides of A to B is 4/11.

Since 4/11 is not equal to 1/2, figure B is not a scale copy of figure A.

It should be noted that a graph gives a diagrammatic representation of an information.

Here, the rectangles are formed by decreasing the length and increasing the width, each by the same amount.

In constructing 98% confidence intervals for means, it is true that the statistic is good enough, and is less uncertain.

A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.

Your level of confidence in your findings is shown by the confidence interval. You can never be certain that your results will hold for future surveys or experiments. In statistics, being 95% or 98.5% certain is typically seen as "good enough."

Answer:

6. x + x + 14 = 90

   2x + 14 = 90

   2x = 76

   x = 38

angle b = 38 + 14 = 52°

7. angles on a straight line add up to 180°

   x + x - 32 = 180

   2x = 212

    x = 106°

angle d = 106 - 32 = 74°

8. vertically opposite angles are equal

   7x - 80 = 3x

    -80 = -4x

     20 = x

angle 1 = 7(20) - 80 = 60°

angle 2 = 3(20) = 60°

The equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

The number satisfying this equation is -25.

In the question, we are asked to find the number when twice the difference of the number and 8 is equal to thrice the sum of the number and 3.

We assume the number to be x.

The expression representing twice the difference between the number and 8, can be shown as 2(x - 8).

The expression representing thrice the sum of the number and 3, can be shown as 3(x + 3).

We are informed that these two expressions are equal. This can be shown as the equation:

2(x - 8) = 3(x + 3).

Thus, the equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

Now, to find the number, we solve the equation as follows:

2(x - 8) = 3(x + 3),

or, 2x - 16 = 3x + 9 {Simplifying},

or, 2x - 16 + (16 - 3x) = 3x + 9 + (16 - 3x) {Adding (16 - 3x) to both sides of the equation},

or, 2x - 16 + 16 - 3x = 3x + 9 + 16 - 3x {Simplifying},

or, -x = 25 {Simplifying},

or, -x(-1) = 25(-1) {Multiplying both sides of the equation with -1},

or, x = -25 {Simplifying}.

Thus, the number satisfying the equation is -25.

let

number of children tickets = x

number of adult ticket sold = 1 / 3 x

The greatest number of adult tickets sold if the box office receipts was not more than $3,190 can be calculated as follows:

The equations that represent the situation is as follows:

5.50x + 8.50 (1/3 x) = 3190

5.50x + 2.83333333333x = 3190

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

The triangle is shown below.

From the triangle, A  is the concurrency point of angle bisectors of all vertices.

Consider ΔAYD,

Using the Pythagorean theorem,

AD² = AY² + YD²

5² = AY² + 4²

25 = AY² + 16

AY² = 25 - 16

AY² = 9

AY = √9 = 3 cm

Consider triangles ADY and ADZ.

∠AYD ≅∠AZD=90

∠ADY≅∠ADZ ( Angle bisector)

AD ≡ AD (common side)

The inequality that explains why the three segments cannot be used to construct a triangle is ED + EF < DF

From the question, we are to determine which of the given inequalities explains why the three segments cannot be used to construct a triangle

From the given information,

Line DE is about half the length of line DF

That is,

ED = 1/2 DF

Also,

Line FE is about one-third of the length of line DF

That is,

EF = 1/3 DF

Then, we can write that

ED + EF = 1/2DF + 1/3DF

ED + EF = 5/6 DF

Since,

5/6 DF < DF

Then,

ED + EF < DF

Hence, the inequality that explains why the three segments cannot be used to construct a triangle is ED + EF < DF

65c + 90s [tex]\geq[/tex]600

Step-by-step explanation:

since he needs AT LEAST 600$ then the sign should look like that. 65 dollars per car, and c represents the amount of cars, and 90 per SUV and s represents how many SUVS

B. 65c + 90s ≥ 600 is the correct option.

Our friend really wants to buy the newest cell phone which will cost him $600. He gets a job detailing cars and SUVs and plans to save all the money he earns.

Inequality can be defined as the relation of the equation contains the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,

If he gets paid $65 to detail a car and $90 to detail an SUV

The inequality form for above condition so he can earn at least $600

= 65c + 90s ≥ 600, where c = cars and s = SUV

Thus, the required inequality is given by 65c + 90s ≥ 600.

The confidence interval for the mean usage of water is (18.7,20.5).

Given population standard deviation of 2.4, mean of 19.5 gallons per day and confidence interval of 98%.

To find out the confidence interval we have to first find margin of error.

μ=19.5

σ=2.4

α=0.98

α/2=0.49

We have to find the z value for the p value 0.49 which is z=2.33

Margin of error=z*μ/[tex]\sqrt{n}[/tex]
