Please Help on this Geometry question
Answer:
50 degrees
Step-by-step explanation:
You can see that angle ADC is composed of angle ADB and angle BDC
Angle ADB is 38 degrees and angle BDC is 12 degrees
Therefore angle ADC is 50 degrees
Angle ADC is opposite from angle ABC so they are congruent.
So angle ABC is 50 degrees

A bakery sells taro, red bean and green tea pues. 65% of the pies are taro pies. 40% of the remaining pies are red bean pies. How many pies are there altogether?
Answer: 1,800 pies in total
Step-by-step explanation:
A key detail missing is that there are 378 green tea pies.
Assuming the total number of pies is x.
65% of this is taro pies. This leaves 35% to be red bean pies and green tea pies.
If 40% of this remaining 35% are red bean pies, that means that 60% are green tea pies.
= 35% * 60%
= 21% of the total are green tea pies
There are 378 green tea pies and this is 21% of the total number of pies.
378 = 0.21 * x
x = 378 / 0.21
= 1,800 pies in total

Jacks Plumbing charges customers $100 per hour for repair jobs. Al's Plumbing charges according to the equation y = 75x + 50, where x = time in hours and y = cost
dollars
Explain why Ars Plumbing charges less than Jacks Plumbing for a 4-hour repair job.
Does Als Plumbing charge less than Jacks Plumbing for all repair jobs? Explain why or why not.
Answer:
As given,
Per hour cost of Jack's plumbing = $100
Also,
Al's plumbing charges = 75x + 50 where x = time in hours .
Now,
Al's plumbing cost for 4 hours:
Here , x = 4
⇒75x + 5 = 75(4) + 50 = 300 + 50 = 350
∴ we get
Al's plumbing cost for 4 hours = $350
Now,
As Jack cost for 1 hour = $ 100
⇒ For 4 hour = 4×$100 = $400
∴ we get
Jack's plumbing cost for 4 hours = $400
As we can see that
$ 400 > $350
⇒Jack's plumbing cost for 4 hours > Al's plumbing cost for 4 hours
Now,
Al's plumbing charges = 75x + 50 where x = time in hours .
For 1 hour
75x + 50 = 75(1) + 50 = 125
Al's 1 hour cost = $125
whereas Jack Plumbing cost for 1 hour = $100
∴ we get
$125 > $100
⇒Al's 1 hour cost > Jack's 1 hour cost
Now,
Al's 2 hour cost
75x + 50 = 75(2) + 50 = 150 + 50 = 200
Al's 1 hour cost = $200
whereas Jack Plumbing cost for 2 hour = $200
∴ we get
$200 = $100
⇒Al's 2 hour cost = Jack's 2 hour cost
Now,
Al's 3 hour cost
75x + 50 = 75(3) + 50 = 225 + 50 = 275
Al's 1 hour cost = $275
whereas Jack Plumbing cost for 3 hour = $300
∴ we get
$275 < $300
⇒Al's 3 hour cost < Jack's 3 hour cost
Als0,
Jack's plumbing cost for 4 hours > Al's plumbing cost for 4 hours
∴ we get
We can not say that Als Plumbing charge less than Jacks Plumbing for all repair jobs.
Because the charge is fluctuating ,
For 1 hour , Aly' charge is grater whereas The 2 hour cost of Jack's is higher.
So, the Correct answer is - No, Al's Plumbing charge is not always less than Jacks Plumbing for all repair jobs.
Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 99 people in the 18-21 age bracket and finds that 84 of them respond and 15 refuse to respond. When 276 people in the 22-29 age bracket are contacted, 257 respond and 19 refuse to respond. Assume that 1 of the 375 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who agreed to respond.
Answer:
The probability of getting someone in the 18-21 age bracket or someone who agreed to respond [tex]= 0.365[/tex]
Step-by-step explanation:
The counts are as follows
Age Group No of people contacted No of refusals Total
18-21 88 8 96
22-29 240 42 282
Total 328 50 378
The probability of getting some one in the age bracket of 18-21 or some one who refused to respond is
[tex]= \frac{96}{378} + \frac{50}{378} - \frac{8}{378} \\= \frac{96+50-8}{378} \\= \frac{138}{378} \\= 0.365[/tex]

Answer:
2%
Step-by-step explanation:
Answer: 2%
Step-by-step explanation: Method 1
Express the ending population as a percentage of the starting population:
127000 /129540= 1.02
1.02×100= 102%
Subtract the starting 100% to get the percent increase:
102%−100%= 2%

Suppose a normal distribution has a mean of 266 and a standard deviation of
12. What is P(x> 242)?
O A. 0.16
B. 0.475
C. 0.84
D. 0.975
0.975 is P(x ≥242) with a mean of 266 and standard deviation of 12
The required value of P(x> 242) = is 0.975 for normal distribution. Option D is correct.
The normal distribution has a mean of 266 and a standard deviation of
12. What is P(x> 242) is to determine.
Whata is normal distribution?Normal distributions can be altered to standard normal distributions by the formula:
Z = (X - μ)/σ
Where x is a value from the initial normal distribution, μ is the mean of the initial normal distribution, and σ is the standard deviation of the initial normal distribution. The standard normal distribution is periodically called the z distribution.
Now,
z = X - 266 /12
p(x > 242) = P [(X - 266)/12 ≥ (242 - 266)/12]
p(x > 242) = P [z ≥ -24/12]
p(x > 242) = P [z ≥ -2]
p(x > 242) = P [z ≤ 2]
p(x > 242) = 0.975 (from Z table).
Thus, the required value of P(x> 242) = is 0.975. Option D is correct.
