Answer:

Step-by-step explanation:

5, 7 and 8 are midsegments of the given triangle.

As per property, midsegment is parallel to one of the sides and is equal to its half by measure.

Midsegment with the length of 8 is parallel to side with the length of x and is half of its size:

Answer:

D.Initial value: 20, rate of change: -10

Step-by-step explanation:

As you see, it starts with x=1, y=20 so the initial value is 20 and as x goes up y changes by -10 so thats ur rate of change

Hope this helps! :)

Answer:

25 is 2.5 standard deviations from the mean.

Step-by-step explanation:

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean.

In this question:

Mean of 15 and a standard deviation of 4, so [tex]\mu = 15, \sigma = 4[/tex]

How many standard deviations from the mean is 25?

We have to find Z when [tex]X = 25[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{25 - 15}{4}[/tex]

[tex]Z = 2.5[/tex]

So 25 is 2.5 standard deviations from the mean.

2.5

Answer: [tex]\overline{IJ}\cong \overline{MN}[/tex]

Step-by-step explanation:

Given: In triangle HIJ and triangle MNO we have

[tex]\overline{HI}\cong \overline{NO}, \angle{I}\cong \angle{N} ,\angle{H}\cong \angle{O}[/tex]

here, HI and NN are the included side between  ∠I & ∠H and ∠N and ∠O.

So , by ASA congruence rule,

ΔHIJ ≅ ΔMNO

So by CPCTC  (corresponding parts of the congruent triangles are congruent)

[tex]\overline{IJ}\cong \overline{MN}[/tex]

Answer:

([tex]\frac{1}{2}[/tex], [tex]\frac{-1}{2}[/tex])

Step-by-step explanation:

Use the midpoint formula to solve.

1) Given 2 points: ([tex]x_{1}[/tex], [tex]y_1[/tex]) and ([tex]x_2[/tex], [tex]y_2[/tex])

The midpoint formula would be ([tex]\frac{x_1+x_2}{2}[/tex], [tex]\frac{y_1+y_2}{2}[/tex]).

2) Based on this, we can easily find the midpoint of AB.

3) With this information, we can solve for the midpoint.  

([tex]\frac{-3+4}{2}[/tex], [tex]\frac{-5+4}{2}[/tex]) --> ([tex]\frac{1}{2}[/tex], [tex]\frac{-1}{2}[/tex]) --> This is your answer.

Answer: It increased by 78.89%

Step-by-step explanation:

2.810 / 3.562

=0.7889

78.89%

The approximate percent of change is 26.76% increase.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The average price for gasoline per gallon is $3.562.

last year the average price for gasoline per gallon was $2.810.

∴ The net amount change is  $(3.562 - 2.810) = $0.752.

Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,

= (0.752/2.810)×100%.

= 26.76% increase.

Answer:

1) Irrational

2) Rational

3) Irrational

4) Rational

5) Rational

Step-by-step explanation:

A rational number is one that can be expressed as a ratio of 2 integers while an irrational number is one that can not be expressed like that. Another difference is that rational numbers can have finite or recurring decimals while irrational numbers have infinite and non - recurring decimals.

1) -20π is an irrational number because π contains infinite decimal digits

2) -26.23 is a rational number because it can be expressed as a ratio of 2 integers

3) -2√3 is an irrational number because √3 contains infinite decimal digits

4) -√1 is a rational number because √1 is a perfect square root and as such it can be expressed as a ratio of 2 integers.

5) 95.60 is a rational number because it can be expressed as a ratio of 2 integers

Answer:

x = 31

Step-by-step explanation:

So, the angle of a line is 180 degrees. This is a very important fact, because this means that (5x - 16) + (x + 10) = 180 degrees.

Note: The parenthesizes are not needed, but I put them there to symbolize the adding of those two angles that make up the line.

Adding like terms, we get:

6x - 6 = 180

Move the -6 over to the right side.

We get:

6x = 186

Dividing both sides by 6, we get the value of x:

x = 31

Step-by-step explanation:

2, 3, 13, 14, 16, 20, 20, 20, 30, 40

Mean: the average of a data set.

2 + 3 + 13 + 14 + 16 + 20 + 20 + 20 + 30 + 40 / 10 = 178/10 = 17.8

Median: the middle of the set of numbers.

16 + 20 / 2 = 36/2 = 18

Mode: the most common number in a data set.

203 2/3

Step-by-step explanation:

Add all the wholes (55+55+46+46, that gets you 202), then, convert 2/3 to sixths (4/6). Then, add the fractions (4/6+4/6+1/6+1/6, that gets you 10/6, or 1 4/6). Now, our answer is 203 4/6, which can be simplified to 203 2/3.

Answer/Step-by-step explanation:

5. Given that ∆FGH ≅ ∆TSU, all three angles and sides of ∆FGJ are congruent to all corresponding angles and sides of ∆TSU.

Thus:

Since, <HFG in ∆FGH corresponds to <UTS in ∆TSU, therefore:

<HFG ≅ <UTS

7. Given that ∆FGH ≅ ∆FGL, the following are the corresponding sides and angles:

FG ≅ FG

GH ≅ GL

FH ≅ FL

<FGH ≅ <FGL

<FHG ≅ FLG

<GFH ≅ GFL
