sin∅ = opposite over hypotenuse
Since we have a right triangle, we can use trig to help us solve for missing values:
sin30° = 4/x
xsin30° = 4
x = 4/sin30°
x = 8

Step-by-step explanation:
you then have to distribute the answer not subtract 9 1/4 from 1.5
you have to do the parenthesis next
4.5/0.5=45/5=9
then
1.5*9= 13.5

An airline company claims in a recent advertisement that more than 94% of passenger luggage that is lost is recovered and reunited with the customer within 1 day. Hunter is a graduate student studying statistics. For a research project, Hunter wants to find out whether there is convincing evidence in support of the airline company's claim. He randomly selects 315 passengers of the airline whose luggage was lost by the airline and found that 276 of those passengers were reunited with their luggage within 1 day. Are all of the conditions for this hypothesis test met, and if so, what are the null and alternative hypotheses for this hypothesis test?
Answers
Answer:
The null hypothesis is [tex]H_o : p \le 0.94[/tex]
The alternative hypothesis is [tex]H_a : p > 0.94[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 315
The population proportion is p = 0.94
The number of luggage that was recovered and reunited with the passenger in one day is k = 276
Generally the sample proportion is mathematically represented as
[tex]\r p = \frac{k}{n}[/tex]
=> [tex]\r p = \frac{276}{315}[/tex]
=> [tex]\r p = 0.876[/tex]
The null hypothesis is [tex]H_o : p \le 0.94[/tex]
The alternative hypothesis is [tex]H_a : p > 0.94[/tex]

The point O(4,-4) would map onto itself after a reflection across the line y=-x.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To find out which point would map onto itself after a reflection across the line y=-x, we need to reflect the given points across the line and see which one ends up in its original position.
The reflection of a point (x, y) across the line y=-x is (-y, -x).
Let's apply this formula to each given point:
The reflection of O(4,-4) across y=-x is (-(-4), -4) = (4, -4), which is same as the original point.
The reflection of O(4,0) across y=-x is (0, -4), which is not the same as the original point.
The reflection of O(0,4) across y=-x is (4, 0), which is not the same as the original point.
The reflection of O(4,4) across y=-x is (-4, -4), which is not same as the original point.
Therefore, the point O(4,-4) would map onto itself after a reflection across the line y=-x.

Since the war has started, you have lost 1/4 of your total body weight. If you now weigh 150 lb, how much did you weigh when the war started?
Answers
Answer:
200
Step-by-step explanation:
1/4 of 150 would be 50
If you lost 1/4 of 200
200 - 50
You would get 150
Therefore your answer is 200
Also, think of it this way, if you lost 1/4 of your body weight, 150 is 3/4 of your entire body weight- so the other 1/4 would be 50
50 x 4 = 200
1/4 = 50
2/4 = 100
3/4 = 150
4/4 = 200

three friends shared a basket of strawberries. Sue got 2/7 of the strawberries. Jim got 54 more strawberries than sue. Dan got 78 strawberries. How many strawberries were there in the basket.
Answers
Answer:
Step-by-step explanation:
Let x be the total no. of strawberries, Let Sue be "S", Let Jim be "J" and Dan be "D"
S = 2x/7
J = 54+S -> J = 54+(2x/7)
D = 78
J+D = 5x/7
54+(2x/7)+78 = 5x/7
132+2x/7 = 5x/7
132 = (5x/7)-(2x/7)
132 = 3x/7
132*7 = 3x
924/3 = x
x = 308.
Therefore, there were initially 308 strawberries in the basket.
Of which; Sue had two-sevenths: 88, Jim had 142 and Dan had 78
To verify our answer, add these to see if we get 308
S+J+D = 308
88 + 142 + 78 = 308

Determine whether each statement below justifies the claim. Select Yes or No for each statement

Answers
A) Intersecting lines allow for the creation for angles with a common vertex
B) if one of the angles is a right angle, the angle the vertical to it must also be a right angle
Step-by-step explanation
C) is not true because linear pairs are supplementary not complementary because a line = 180°
B) it’s true because they are corresponding vertical angles
A) it’s true because they all have the same starting point or vertex
The statements that justifies don's claim about perpendicular lines being lines that intersect such that at least one of the angles is a right angle are; Option A; Intersecting lines allow for the creation of four angles with a common vertex.
Option B; If one of the angles is a tight angle, the angle vertical to it must also be a right angle
This is about perpendicular lines and whether they form right angles upon intersection. To answer this, let us look at the options; Option A; Yes, this statement is true because when a perpendicular line intersects another one, they will form 4 angles since they will all have the same starting point or common vertex.Option B; Yes, this statement is true because from corresponding angles theorem, we can say that they are corresponding vertical angles because they are congruent due to the transverse perpendicular line.Option C; No, this statement is not true because the angles would form linear pairs and as such since angles on a line sum up to 180°, it will also occur here and as such we can say they are supplementary angles.Read more at; brainly.com/question/18373668

Cost of apples:

$5.64
$7.52
$9.40
Answers
Answer:
I think it is the 3.76 I am 85%sire
Answer:
YEAH IT IS :D
Step-by-step explanation:
First you need to get 1 pound. 2 pounds is 3.76 divide it by 2 and get 1.88. Multiply it by so you can get 3 pounds: 1 x 3 = 3 pounds. 1.88 x 3 is 5.64. Now to get 4 pound you add 1.88 again to 3 pounds to add a pound and you get 7.52. Now add 1.88 to 4 one more time to get 5 pounds: 4 + 1 = 5 pounds. And 7.52 + 1.88 = 9.40. Now you checked the whole table and they are right so yes it is proportional to the weight of apples!

Slope = 1
Equation: y= 1x + 1 or y= x + 1
Step-by-step explanation:
The slope is one because the rise over run from point (-1,0) to (0,1) is 1/1, and 1/1 is equal to 1. This means in the form y=mx + b the slope would be put in for m. y= 1x + 1. The plus one is because the line crosses the y axis at y = 1. When you are writing the equation technically you do not need to write it as y= 1x +1 you can just do y = x + 1 because there is only 1 x.

Answers

Step-by-step explanation:
in one minute he scoops 4.25 cups which you get by dividing 8.5 and 2 and then you multiply that by 8 and you get 34 cups
Answer:
34 scoops
Step-by-step explanation:
If I were you I would find how many cups nathan can scoop in a minute because not only its the easiest way it's the fastest so what you can do to find that is divide 8.5 by 2 which is 4.25.
since you know how many he can scoop in a minute you can do 8 times 4.25 because their is 8 minutes and 8 times 4.25 is 34
