Answer:

97

Step-by-step explanation:

Angle on a straight line = 180

106 + ∠st = 180

∠st = 180 - 106 = 74

x = ∠st + 23

= 74 + 23

= 97

Answer:

51 degrees

Step-by-step explanation:

This is a scalene triangle. Which means it sums up to 180 degrees. Therefore, you have to add up all the degrees to 180. 106+23 is 129, and 180 - 129 is 51.

A store sells shirts at a price of 2 for $5.00. At this price, how much do 7 shirts cost?

Answers

Answer:

$17.50

Step-by-step explanation:

2 goes into 7 3 times, and 5 times 3 is $15.00, so theres one shirt left. If 2 shirts cost $5, one will cost $2.50. So, 15+2.50= $17.50

5/2 equals 2.50 so 2.50x7 equals 17.50

The monthly electric bills in a certain community are normally distributed, with a mean of $245 and a standard distribution of $55. If there are 461 households in the community, about how many of them have electric bills less than $200?

A. 45
B. 21
C. 95
D. 81

Answers

95 households have electricity bills of less than $200. Option C is correct.

Given that,
The monthly electric bills in a certain community are normally distributed, with a mean of $245 and a standard distribution of $55. There are 461 households in the community, how many of them have electric bills less than $200 is to be determined.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.


probability for the number of households has electric bills less than $200.
x = 200 , μ = 245 ; σ = 55
Now,
Probability,
z (p < 200) =  [tex]\frac{X -\mu}{\sigma}[/tex]
z (p < 200) =  (200 - 245)/55
                = --45/5
                = -0.818181
p < 200 = 0.206 (from z table)

Now, the number of households that has electricity bill less than $200,
= 461 * 0.206
= 94.966
≈ 95

Thus, 95 number of household have electricity bills of less than $200. Option C is correct.

The answer is x=6 !!!!

Answer:

x = 6

Step-by-step explanation:

First, subtract 7 from both sides to get x alone. That will give you 4x = 24 .

Then divide both sides by 4 to remove the coefficient of x. That means x = 6.

4x+7=31

Assume that last year in a particular state with 700000 children there were 1205 children out of 32600 in a random sample who were diagnosed with Autism Spectrum Disorder. Nationally, 1 out of 88 children are diagnosed with ASD. Is there sufficient data to show that the incident rate of ASD is higher in that state than nationally

Answers

Answer:

We accept Hₐ   there is enough evidence to claim that the incidence of ASD is bigger in this state than it is nationally

Step-by-step explanation:

The population follows a binomial distribution, and the fact that

p₀ = 1205/32600 = 0,03696       and then q₀  = 1-0,03696 = 0,9630

And both

p₀*n = 0,03696*32600 = 1205 > 10

q₀*n = 31395 > 10

The binomial distribution can be approximate to a Normal Distribution, then we need to develop a one tail test ( to the right) to evaluate if the claim " There is sufficient data to show that the incident rate is higher in the mentioned state than the national one.

Therefore:

Hypothesis Test                    H₀    ⇒    p₀ = p

Alternative Hypothesis        Hₐ   ⇒     p₀ > p

p is the population proportion mean

p = 1/88  =  0,011

We must test having a very wide Confidence Interval since the matter we are trying is public health then we choose CI = 95 %

CI = 95 %     α = 5 %    α = 0,05    

Critical value for 0,05  is from z-table  z(c) = 1,64

We compute z(s)

z(s) =( p₀ - p )/ √ p₀*q₀/n

z(s) = 0,03696 - 0,011 / √ (0,03696*0,9630)/ 32600

z(s) =  0,02596* 180,55/ √ 0,0356

z(s) = 4,687 / 0,189

z(s) = 24,9

Comparing  z(s) and z(c)   24,9 > 1, 64

z(s) is out of the acceptance region and we have to reject H₀

We accept Hₐ   there is enough evidence to claim that the incidence of ASD is bigger in this state than it is nationally

Please answer quickly! merry christmas (: Read the story.Life on the Sea The storm roiled on the horizon as rough waves rocked the helm of the fishing vessel. The captain had known the storm was cominghe had watched the weather reports for the past several days of the journeybut he started to question his decision as the waves got more powerful. One wave slapped the vessel and knocked him to the deck; when he stood up on unsteady feet, he grabbed the wheel with both hands. Though he had been a fishing boat captain for years and knew that the sea was the safest place for a vessel in a storm, these moments always terrified him. He had spent most of his life on the sea; he knew the habits and nuances of the water like it was his closest friend. The calmness that he felt when the water was placid wasnt like any stillness that he experienced on land. And though he didnt like the choppy waves when he could barely stay upright, he knew that these moments were necessary too. It was like lifein order to get to the peace, he had to weather the storm. His wife, Marla, didnt understand his obsession with the water, why he spent months of the year navigating a boat full of crab fishermen to isolated spots of the ocean hundreds of miles from shore. She couldnt grasp why he didnt get the same satisfaction from life behind a deskthe stable job in an office downtown that Marla wanted him to have. He had tried things her way, but that had only lasted a couple years; after a while, she could tell that he was miserable, and she gave him her permission to do what he loved. He gave his job two weeks notice and was back on the sea right away. He knew he missed things while he was away on these fishing boats: he listened to his wifes voice over an unreliable cell phone connection. Hed had to watch his daughter Ky speak her first words on a video that chirped into his phone. And though hed been there for her first steps, hed missed her first day of preschool, and there would inevitably be other milestones that he would miss. He stared into the blackness of the storm and knew that the fishermen below deck were relying on him to get them safely back to their familieshe knew this because he was aware of how his own family relied on him. He knew that he had to stay focused, even when he wanted to think about what his wife was doing now. He would see her in a weekand hed be able to take his daughter to school again. Hed be able to go to the grocery store and the park and do all the everyday things that he missed while at sea. He touched the picture of his family that was inside his raincoat as the next wave approached. He imagined their voices telling him that they were proud of him, and it filled him with a strength that he hadnt felt at other times during this journey. In the morning, the storm would die down, and he would enjoy the quiet. In the morning, he would call his daughter and tell her about the big storm and hear the wonder in her voice as he described the size of each wave. But for now, he was a man on a mission; he took a deep breath and held onto the steering wheel with every bit of his strength. Lets go, he thought as the biggest wave of all crashed into the boat.Question 1Part AIn the story "Life on the Sea," how does the captain mostly feel when he is on the sea?proudguiltyconfidentmiserableQuestion 2Part BWhich excerpts from the story best support the answer in Part A?Select the two correct answers."He gave his job two weeks notice and was back on the sea right away.""The calmness that he felt when the water was placid wasnt like any stillness that he experienced on land.""The storm roiled on the horizon as rough waves rocked the helm of the boat.""He had spent most of his life on the sea; he knew the habits and nuances of the water like it was his closest friend." one bucket of gravel has a mass of 7.05 kg. what is the mass of 20 buckets of gravel in kilograms?
