Answer:
y≈94.31
Step-by-step explanation:
Hi there!
We're given a right triangle (notice the 90 degree angle), the measure of one of the legs (one of the sides that make up the right angle) as 46, the other one as y, and one of the angles as 26°
We want to solve for y
We can use a trigonometric ratio to do that.
First, let's recall the three most-well known ratios:
Sine is [tex]\frac{opposite}{hypotenuse}[/tex]
Cosine is [tex]\frac{adjacent}{hypotenuse}[/tex]
Tangent is [tex]\frac{opposite}{adjacent}[/tex]
Since we are given one of the angles, let's find out which sides are the opposite, adjacent, and hypotenuse, in reference to the given angle (the 26° angle)
In reference to that angle, the side opposite to that angle (also the side known as "opposite) is the side marked as 46, the adjacent side is y, and the hypotenuse is the unmarked side
Since we know the opposite and adjacent, let's use the ratio for tangent
Since we based our labels off of the 26 degree angle, the tangent ratio is the tangent OF 26, or tan(26)
tan(26)=[tex]\frac{46}{y}[/tex]
Now we need to solve the equation
Start by multiplying both sides by y
tan(26)*y=46
Divide both sides by tan(26)
y=[tex]\frac{46}{tan(26)}[/tex]
Plug [tex]\frac{46}{tan(26)}[/tex] into your calculator, and remember to have the calculator on degree mode
[tex]\frac{46}{tan(26)}[/tex]≈94.31
Remember that [tex]\frac{46}{tan(26)}[/tex] is equal to y, which means that y is about 94.31
Hope this helps!

<4 and <8 are in corresponding positions in relations to the lines' intersection of the transversal, therefore they are corresponding angles.
<1 and <8 are on the outside, meaning they are exterior and on opposite sides. This means they are alternate exterior angles.
<1 and <5 are in corresponding positions in relations to the lines' intersection of the transversal, therefore they are corresponding angles.
<4 and <7 are on the inside, meaning they are interior and on the same side. This means they are same side interior angles.

Step-by-step explanation:
Let the number be x
Sum of x and -3.2 : x + (-3.2) = x - 3.2
1/4 times the sum of a number and −3.2 = (1/4) * (x - 3.2)
[tex]\dfrac{1}{4}* \left( x - 3.2 \right) = 1.8\\\\\Multiply \ the \ whole \ equation \ by \ 4 \\\\4*\dfrac{1}{4} *(x - 3.2) = 1.8*4\\\\\\x - 3.2 = 7.2\\\\Add \ 3.2 \ to \ both \ sides\\\\\\x = 7.2 + 3.2\\[/tex]

.A study of 800 homeowners in a certain area showed that the average value of the homes was $82,000, and the standard deviation was $5000. If 50 homes are for sale, find the probability that the mean of the values of these homes is greater than $83,500.
Answers
There is 1.70% that 50 homes have a value greater than $83,500.
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\where\ x=raw\ score,\mu=mean,\sigma=standard \ deviation,n=sample\ size[/tex]
μ = $82000, σ = 5000, n = 50. Hence for x > 83500:
[tex]z=\frac{83500-82000}{5000/\sqrt{50} }\\\\\\z=2.12[/tex]
From the normal distribution table, P(x > 83500) = P(z > 2.12) = 1 - P(z < 2.12) = 1 - 0.9830 = 0.0170 = 1.70%

Step-by-step explanation:

A consultant has developed a new instruc- tional booklet intended to reduce the time an inexpe- rienced kit builder will need to assemble the device. In a test of the effectiveness of the new booklet, 15 nov- ices require a mean of 2.90 hours to complete the job. Assuming the population of times is normally distrib- uted, and using the 0.05 level of significance, should we conclude that the new booklet is effective? Determine and interpret the p-value for the test.( DATA SET ) Note: Exercises 10.33 and 10.34 require a computer and statistical software.
Answers
Testing the hypothesis using the z-distribution, it is found that since the p-value of the test is of 0.0262 < 0.05, it can be concluded that the new booklet is effective.
At the null hypothesis, we test if there has been no improvement, that is, the time is still of 3 hours. Hence:
[tex]H_0: \mu = 3[/tex]
At the alternative hypothesis, we test if there has been improvement, that is, the time is of less than 3 hours. Thus:
[tex]H_1: \mu < 3[/tex]
We have the standard deviation for the population, thus, the z-distribution is used. The test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the population.n is the sample size.In this problem, the values of the parameters are: [tex]\mu = 3, \sigma = 0.2, \overline{x} = 2.9, n = 15[/tex].
Then, the value of the test statistic is:
[tex]z = \frac{2.9 - 3}{\frac{0.2}{\sqrt{15}}}[/tex]
[tex]z = -1.94[/tex]
The p-value of the test is the probability of finding a sample mean of 2.9 hours or less, which is the p-value of z = -1.94.
Looking at the z-table, z = -1.94 has a p-value of 0.0262.
Since the p-value of the test is of 0.0262 < 0.05, it can be concluded that the new booklet is effective.

There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers.
Similarly 2nd, 3rd and 4th digits.
Hence each digit will have 6 possibilities.
Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296
ANSWER 2: Without Repetition
4 digits __ __ __ __
Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.
Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.
Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360

260 Student Edition
Grates in KM
Answers
Answer:
The light travels distance in 1 minute=18 million kilometers
The light travels distance in 1 second=0.3 million kilometers
Step-by-step explanation:
We are given that
Light travels total distance in 10 minutes=180 million kilometers
We have to find the distance travels by light in 1 minute and in 1 seconds.
By unitary method
Distance travel by light in 1 min=million kilometers=18 million kilometers
Distance travel by light in 1 min=18 million kilometers
We know that 1 minute=60 seconds
In 60 seconds, light travels distance =18 million kilometers
In 1 second, light travels distance = million kilometers
Hence, the light travels distance in 1 minute=18 million kilometers
The light travels distance in 1 second=0.3 million kilometers

The width of a rectangular painting is 3 in. less than the length. The area of the painting is 40 in ^2 .Find the length and width.
Answers
Answer:
Mark me as brainlist
Step-by-step explanation:
a) (h + 5)(2h + 8) is the expression for the combined area of the painting and frame
b) The combined area when h = 12 is 544 square inches
c) The combined area when h = 15 is 760 square inches
Solution:
Given that,
A frame that is 2.5 inches wide goes around the painting
The frame will go around all 4 sides of the painting.
That means that the length of each side of the painting will increase by 2.5 inches
Therefore,
The height of painting and frame is:
h = h + 2.5 + 2.5
h = h + 5
(2.5 inches on the top and the bottom)
Also given that,
Width of a rectangular painting is 3 inches more than twice the height
w = 3 + 2h
Now the width of painting and frame is:
w = 3 + 2h + 2.5 + 2.5
(Again, 2.5 inches on the top and the bottom)
w = 2h + 8
Thus the combined area of the painting and frame is:
B) Substitute h = 12 inches
Thus the combined area when h = 12 is 544 square inches
C) Substitute h = 15 inches
Thus combined area when h = 15 is 760 square inches
