Answer:
11.00
Step-by-step explanation:
1. Since he's trying to buy 2 pairs you can multiply 27.00 by 2 or you can just add 27.00+27.00 and will get 54.00
2. Subtract 65.00-54.00
3. and you'll get 11.00

Answer:
use the ASA postulate with alternate interior angles
Step-by-step explanation:
Congruence in general
For proving triangle congruence, there are basically 4 ways to do it. All require at least one side. They are ...
SSS - 3 corresponding sides are shown to be congruentSAS - two corresponding sides and the angle between them are shown to be congruentASA - two corresponding angles and the side between them are shown to be congruent (this one is used here)AAS - two corresponding angles and the side next to (a particular) one of them are shown to be congruentWhen applied to right triangles, the right angle counts as one of the angles, and two sides determine the third, so these can become the LL, HL, HA, LA theorems, where the letters (H, L, A) stand for (hypotenuse, leg, angle), respectively.
__
Approach to this problem
Of course, you're familiar with the relationship between angles where a line crosses parallel lines. Those relationships can help you identify two congruent angles in each triangle. The fact that the triangles share a side between those angles gives you a clue that you will be using the ASA postulate for your proof.
Specifics
1. AB ║ CD and AD ║ BC . . . . given
2. ∠1≅∠3 . . . . alternate interior angles at a transversal of parallel lines are congruent
3. AD≅DA . . . . reflexive property of congruence
4. ∠2≅∠4 . . . . alternate interior angles at a transversal of parallel lines are congruent
5. ∆DAB ≅ ∆ADC . . . . ASA postulate
When the population distribution is normal, the statistic median {|X1 − X tilde|, . . . , |Xn − X tilde|}/0.6745 can be used to estimate σ. This estimator is more resistant to the effects of outliers (observations far from the bulk of the data) than is the sample standard deviation. Compute both the corresponding point estimate and s for the data below. (Round your answers to three decimal places.)25.01, 25.87, 26.34, 26.51, 26.75, 27.24, 27.40, 27.63, 27.83, 27.90, 28.08, 28.13, 28.37, 28.58, 28.59, 28.96, 29.20, 29.22, 29.38, 30.88
Answer:
The corresponding point estimate is 0.882.
The sample standard deviation is 1.373.
Step-by-step explanation:
The data set is:
S = {25.01, 25.87, 26.34, 26.51, 26.75, 27.24, 27.40, 27.63, 27.83, 27.90, 28.08, 28.13, 28.37, 28.58, 28.59, 28.96, 29.20, 29.22, 29.38, 30.88}
Compute the mean as follows:
[tex]\bar X=\frac{1}{n}\sum X\\\\=\frac{1}{20}\times [25.01+25.87+...+30.88]\\\\=\frac{1}{20}\times 557.87\\\\=27.8935[/tex]
Subtract the mean from each value and take the modulus of those values.
The new data set is:
S₁ = {2.8835, 2.0235, 1.5535, 1.3835, 1.1435, 0.6535, 0.4935, 0.2635, 0.0635, 0.0065, 0.1865, 0.2365, 0.4765, 0.6865, 0.6965, 1.0665, 1.3065, 1.3265, 1.4865, 2.9865}
Arrange these values in ascending order as follows:
S₂ = {0.0065 , 0.0635 , 0.1865 , 0.2365 , 0.2635 , 0.4765 , 0.4935 , 0.6535 , 0.6865 , 0.6965 , 1.0665 , 1.1435 , 1.3065 , 1.3265 , 1.3835 , 1.4865 , 1.5535 , 2.0235 , 2.8835 , 2.9865}
There are 20 observations in the data set.
The median value for an even set of values is the mean of the middle two values.
In this case the median will be the mean of the 10th and 11th observations.
[tex]\text{Median}=\frac{10^{th}obs.+11^{th}obs.}{2}=\frac{0.6965+1.0665}{2}=0.8815\approx 0.882[/tex]
Thus, the corresponding point estimate is 0.882.
Compute the standard deviation as follows:
In set S₁ we computed the absolute mean deviations.
Now take the square of these values and divide by (n - 1) to compute the sample variance:
[tex]\sigma^{2}=\frac{1}{n-1}\sum (|X_{i}-\bar X|)^{2}[/tex]
[tex]=\frac{1}{20-1}\times [(2.8835)^{2}+(2.0235)^{2}+...+(2.9865)^{2}]\\\\=\frac{1}{19}\times 35.7953\\\\=1.88396[/tex]
Compute the sample standard deviation as follows:
[tex]\sigma=\sqrt{\sigma^{2}}=\sqrt{1.88396}=1.373[/tex]
Thus, the sample standard deviation is 1.373.

Ok so I wanna know how to solve this. Is it like (3x+6)+24=(2x+8) or like (3x+6)+(2x+8)+24=180
Answer:
24+(2x+8)=3x+6 is the way you set it up
26 is the anser
Step-by-step explanation:
24+2x+8=3x+6
add the 24 and 8
2x+32=3x+6
subtract 6 from both sides
2x+26=3x
subtract 2x from both sides
x=26
a model boat travels at 20 cm per second.How many meters will the boat travel in 2 minutes
Answer:
24 metersStep-by-step explanation:
distance = velocity x time
= 20 cm/sec x 1m/100cm x 60 sec/min x 2 min
= 24 meters.
Maria found the least common multiple of 6 and 15. Her work is shown below.
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . .
Multiples of 15: 15, 30, 45, 60, . . .
The least common multiple is 60.
What is Maria’s error?
Answer:
the lcm would be 30 not 60
Step-by-step explanation:

Answer:
2.25
Step-by-step explanation:
in order to find the scale factor from A to B you need to divide B by A. 13.5÷6=2.25. 11.25÷5=2.25 and 4.5÷2=2.25.
therefore the scale factor is 2.25 because when you multiply the sides from A by 2.25 you get the length of the side from B.
Answer:

A school sold 51 less children’s tickets than adult tickets for the school play. Adult tickets cost $1.25 and children’s tickets cost $0.75. A total of $129.75 was taken in. How many of each kind were sold?
-pls provide work :)
Answer:
80 adult tickets and 29 children tickets
Step-by-step explanation:
c + 51 = a
51 = a - c
c = a - 51
a*1.25 + c*0.75 = 129.75
a = 100 c = 49 a + c = 161.75
a = 80 c = 29 a + c = 121.75

Answer:
(2,-1/2)
Step-by-step explanation:
(9+(-5))/2= 2
(6+(-7))/2= -1/2
Does anyone know how to do this? Im so confused.
================================================
Work Shown:
AB+BC+CD = AD .... segment addition postulate
BC+BC+CD = AD ... replace AB with BC (since AB = BC)
BC+BC+BC = AD ... replace CD with BC (since BC = BC)
3*BC = AD .... combine like terms
3*BC = 12 .... replace AD with 12
BC = 12/3 .... divide both sides by 3
BC = 4
For right triangle PBC, the legs are BP = 3 and BC = 4. We can use the Pythagorean Theorem to find that the hypotenuse is PC = 5
The steps are shown below
(BP)^2+(BC)^2 = (PC)^2
3^2+4^2 = (PC)^2
9+16 = (PC)^2
25 = (PC)^2
(PC)^2 = 25
PC = sqrt(25)
PC = 5

Answer:
4. x = 23 degrees
5. m<A = 33 degrees
m<B = 66 degrees
m<C = 82 degrees
Step-by-step explanation:
4.
(2x + 21) + 90 degrees + x = 180 degrees
(2x + 21) + x = 90 degrees
3x + 21 = 90
3x = 69
x = 23 degrees
5.
2x + x + (2x + 15) = 180 degrees
5x + 15 = 180
5x = 165
x = 33
