10) 80/2 = 40°
11) 105 x 2 = 210°
12) 80 x 2 = 160°
13) (360 - 180 - 108)/2 = 36°
14) (360 - 69 - 95)/2 = 98°
May someone help me please. Solve for x and then find the indicated length. Pleaseee
Answers
Answer:
16
Step-by-step explanation:
3x + 4 = x + 12 [The straight line on the segments AB and BC indicate that they are the same length]
2x = 8 [Subtract x and 8 from both sides]
x = 4 [Divide both sides by two]
Length AB is equal to (3x + 4) as indicated by the diagram. Substituting x = 4, (3 * 4) + 4 = 16

10
Step-by-step explanation:
15 = 1.5t
so t = 15/1.5
= 10
Answer: t = 10
1. Switch sides
- 1.5t = 15
2. Multiply both sides by 10
- 15t = 150
3. Divide both sides by 15
4. Simplify
t = 10
A drug store chain provides an app to its customers to track their shopping habits. One statistic the app
tracks is the amount of money the customer saves by purchasing sale items. The company's sales
team pulls data from the previous year for a random sample of 50 customers. They find that the
mean amount of money saved by these customers in the previous year is $154 with a standard
deviation of $26.
(a) Construct a 99% confidence interval for the true mean amount of money saved by all customers
in the previous year by purchasing sale items.
(b) The sales team would like to repeat this study with the goal of obtaining a smaller margin of
error. Propose two changes that would decrease the margin of error. What are potential
drawbacks if those changes are implemented?
Answers
Answer:
a) CI ( 99% ) = ( 145,45 : 162,55)
b) b) In order to decrease the MOE the sales team has to increase the sample or decrease de 99% of the CI let´s say to 95 % but in that case
you will increase de error type I
Step-by-step explanation:
a) CI = 99 % α = 1% α = 0,01
From z-table z(c) ≈ - 2,325 |z(c)| ≈ 2,325
CI = ( μ₀ ± z(c) * σ/√n )
CI = ( 154 - (2,325) * 26/√50 ; 154 + (2,325) * 26/√50 )
CI = ( 154 - 8,55 ; 154 + 8,55
CI ( 99% ) = ( 145,45 : 162,55)
b) In order to decrease the MOE the sales team has to increase the sample or decrease de 99% of the CI let´s say to 95 % but in that case
you will increase de error type I

Answers
Answer:
See solutions below
Step-by-step explanation:
From the given diagram;
AC = opposite
AB = 7 = hypotenuse
Angle of elevation = 70 degrees
Using SOH CAH TOA
Sin theta = opp/hyp
Sin theta = AC/AB
Sin 70 = AC/7
AC = 7sin70
AC = 7(0.9397)
AC = 6.58
Similarly
tan 70 = AC/BC
tan 70 = 6.58/BC
BC = 6.58/tan70
BC = 6.58/2.7475
BC = 2.39
tan m<A = BC/AC
tanm<A = 2.39/6.58
tan m<A = 0.3632
m<A = 19.96degrees

On a warm summer day, a little girl named Maya layed on the hot sand with her brother George. George loved the beach and loved the water that went with it. Maya and George would always go to the beach every Saturday and play with the kids they made friends with. Since Maya was older than her brother George and loved him she would always surprise him with his favorite kind of ice cream, chocolate. Maya and George were very different in many ways but they always figured out how to get along. Their parents were so happy that they got along and were like best friends, but one day Maya made a big mistake. Maya accidentally broke George’s favorite toy dinosaur. When George found out he cryed so hard and then got very angry at Maya. Maya said sorry so many times but none of them would heal her brother’s loss. Maya told her mom about this and Maya said that she will pay for a new dinosaur with the money she has been saving for a new bike. Her mom agreed and so Maya went and bought George a new dinosaur. When George saw his new toy he was so happy and hugged his sister Maya. Some time later, Maya and George went back to the beach and got their favorite ice cream as usual. Maya saw that her brother was playing with the dinosaur that she bought him. She instantly got so happy, but when her brother looked over at her and smiled so big, she knew that nothing could replace her baby brother.
