3x+6 = -6 + 3x
Answer:
No solution
Step-by-step explanation:
3 x + 6 = − 6+ 3 x
Move all terms containing 'x ' to the left side of the equation.
'6 = − 6 ' Since '6 ≠ − 6' , there are no solutions.

3. The Mathville Zoo only has tigers and
ostriches. The zoo keeper says they have 22
animals and the animals have a total of 70 feet.
Find the number of each kind of animal?
9514 1404 393
Answer:
13 tigers9 ostrichesStep-by-step explanation:
Let t represent the number of tigers. Then the number of feet is ...
4t +2(22 -t) = 70
2t = 26 . . . . . . . . . subtract 44, collect terms
t = 13 . . . . . . . divide by 2; number of tigers
22 -t = 9 . . . . number of ostriches
The zoo has 13 tigers and 9 ostriches.
Robert painted 4/8 of each tile with green paint. He painted 52 tiles. What is the total amount of tiles that he painted green?
Please show an explanation to solve this problem. Thank you.
Answer:
The answer is 26
Step-by-step explanation:
All we do is multiply 4/8 by 52.
52 = 52/1
52/1 * 4/8 = 208/8
208/8 = 26
So the answer is 26.
Hope this helps! :)

match the angle pair with the angle relationship that beat represent the pair of angles.
a)corresponding angles
b)consecutive exterior angles
c)alternate exterior angles
d)alternate interior angles
e)consecutive interior angles
1.angle9 and angle 16
2.angle3 and angle 5
3.angle 7 and angle 15
4.angle 1 and angle 10
5.angle 2 and angle 11
^^^^^places angles(number) with words!! (lettters)
Answer/Step-by-step explanation:
a. Corresponding angles => 3. angle 7 and angle 15
Rationale:
Both angles are found just on the same position on the transversal line s that cuts across the two lines. Thus, they correspond to each other.
b. Consecutive exterior angle => 4. angle 1 and angle 10
Rationale:
Both angles are exterior angles on the same side of the transversal line r that cuts across two straight lines
c. Alternate exterior angles => 1. angle 9 and angle 16
Rationale:
Both angles alternate each other as they lie on the exterior side of the transversal line q, opposite each other.
d. Alternate interior angles => 5. angle 2 and angle 11
Rationale:
Both angles are interior angles that lie alternately to each other on the transversal line r.
e. Consecutive interior angles => 2. angle 3 and angle 5
Rationale:
Both angles are interior angles that lie on the same side of the transversal line p.

3/10n = 4/5
What value of n will make this equation correct
A. 6/25
B. 3/8
C. 1/2
D. 8/3
Answer: B. 3/8
Step-by-step explanation:
3/10n=-4/5
We move all terms to the left:
3/10n-(-4/5)=0
Domain of the equation: 3/10=8
n=3
n!=8
n=R
We get rid of parentheses
3/10n+4/5= 3/8
Answer:
n= (4/5)(3/10)
n=4/5 * 10/3
n=8/3
n=2 2/3

Skyler getting a delivery from Chick-fil-A they charge $3 delivery fee plus $0.25 per mile write an equation to find the total cost y for a delivery that is X miles away
Answer:
y = 3 + 0.25x
Step-by-step explanation:
x represents the miles and if Skyler is charged $0.25 per mile, then x goes with the 0.25. The $3 is a flat fee and doesn't get added any more times then when it is first added.

A college football scout was interested in seeing if a football players height was a good predictor of how fast they were. He randomly sampled 15 different football players and recorded both their heights and their 40 yard dash times. For a person that was 6 ft 3 in tall, he computed a 99% confidence interval for mean speed to be (4.4, 4.8). Which of these options below is the best interpretation of this confidence interval?
a. It can be stated with 99% confidence that the mean speed for players who are 6 ft 3 in tall is between 4.4 and 4.8 seconds.
b. 99% of the time a player will run the 40 yard dash in between 4.4 and 48 seconds.
c. 99% of all players are 6ft 3in tall.
d. It can be stated with 99% confidence that out of the 15 football players sampled those who were oft 3in! tall averaged between 4.4 and 4.8 seconds in the 40 yard dash.
Answer:
a. It can be stated with 99% confidence that the mean speed for players who are 6 ft 3 in tall is between 4.4 and 4.8 seconds.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
For a person that was 6 ft 3 in tall, he computed a 99% confidence interval for mean speed to be (4.4, 4.8). Which of these options below is the best interpretation of this confidence interval?
The the entire population(all people with this height), we are 99% confident that the mean is in this interval, so option a.

If m∠2=40°, what is the measure of ∠1 + ∠6?
Answer:
280°Step-by-step explanation:
∠2 and ∠5 are the vertex angles. m∠2 = m∠5.
The same
∠1 and ∠6.
m∠1 + m∠2 + m∠5 + m∠6 = 360°
Substitute m∠2 = m∠5 = 40° and m∠1 = m∠6 = x:
x + 40° + 40° + x = 360°
2x + 80° = 360° /subtract 80° from both sides
2x = 280° /divide both sides by 2
x = 140°
m∠1 + m∠6 = x + x = 2x
2x = 228°
A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected
from its automatic filling process, the amount of cheese inserted into the ravioli is normally distributed. To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli with mean weight of 15.26 grams and standard deviation of 2.56 grams. The margin of error (ME) to construct a 99% confidence interval for the true mean amount of cheese filling is
A) 2.064 B) 1.432 C) 3.745 D) 1.276 E) 1.797
b. A manufacturer of cheese filled ravioli supplies a pizza restaurant chain. Based on data collected
from its automatic filling process, the amount of cheese inserted into the ravioli is normally distributed. To make sure that the automatic filling process is on target, quality control inspectors take a sample of 25 ravioli and measure the weight of cheese filling. They find the 99% confidence interval of 14.16 to 15.84 grams. Which of the following is the correct interpretation?
I. We are 99% confident that the mean weight of cheese filling in all ravioli made by this process is between 14.16 and 15.84 grams.
II. 99% of all ravioli made by this process will have cheese filling weights between 14.16 and 15.84 grams.
III.We are 99% confident that the interval (14.16, 15.84) contains the mean weight of cheese filling in all ravioli made by this process.
IV. The weight of cheese filling in the ravioli is between 14.16 and 15.84 grams 99% of the time.
A) I only
B) III only
C)I and III.
D) II and III
E) I and IV
Answer: a. B) 1.432
b. E) I and IV
Step-by-step explanation:
a. Margin of error to construct a 99% confidence interval is calculated as
[tex]ME=t.\frac{s}{\sqrt{n}}[/tex]
where
t is the critical value expressed as t-score, which comes from t-distribution;
s is sample standard deviation
n is sample size
In this case, a t-score is used because the population standard deviation is unknown and the sample size is small, n < 30.
The way to find t-score is:
1) Define the degree of freedom, which is sample size minus 1: df = n - 1;
2) Compute alpha: [tex]\alpha=1-\frac{confidence}{100}[/tex];
3) Find the critical probability: [tex]p=1-\frac{\alpha}{2}[/tex]
With the df and critical probability, consulte the t-distribution table and find the score.
For the cheese filling:
df = 24
p = 0.995
t-score = 2.797
Calculating margin of error:
[tex]ME=2.797.\frac{2.56}{\sqrt{5}}[/tex]
ME = 1.432
The margin of error to construct a 99% confidence interval for the true mean amount of cheese filling is 1.432.
b. Confidence interval is an interval in which we have a percentage of certainty that the true population mean is. For example, with a 99% confidence interval of 14.16 to 15.84 grams, we are 99% confident that the true mean weight of cheese filling is between those numbers or that the weight of cheese filling is between 14.16 and 15.84 grams 99% of the time.
