For a two-tailed test, the p-value is the probability of obtaining a value for the test statistic are as follows:
p-value = 0.09 is the probability of obtaining a value for the test statistic.
We are going step by step
Step 1) the p-value is the probability of obtaining a value for the test statistic at least as extreme as that provided by the sample
Step 2) Here the Confidence level is equal to 0.95
So the level of significance is equal to 0.05
p-value = 0.09
Since the p-value is higher than the level of significance that we do not reject the null hypothesis.
Hence the answer, the p-value = 0.09 is the probability of obtaining a value for the test statistic.

The linear function graphed is defined as follows:
y = -1/3x + 11/3.
What is a linear function?The slope-intercept representation of a linear function is given as follows:
y = mx + b
The coefficients of the function and their meaning are listed as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x increases by one.b is the y-intercept of the function, which is the value of the function when it's graph crosses the y-axis.From the graph and from the options, the function crosses the y-axis at y = 11/3, hence the intercept is given as follows:
b = 11/3.
When x increases by 5, from 0 to 5, the function decays from 11/3 to 2, hence the slope is obtained as follows:
m = (2 - 11/3)/5 = (6/3 - 11/3) x 1/5 = -5/3 x 1/5 = -1/3.
Hence the equation is:
y = -1/3x + 11/3.

event B: the sum of the spots on the up-faces is 11
We have 5 + 6, 6 + 5
There are 2 ways for this to happen, therefore,
P(B) = 2/36
P(B) = 1/18
We need to find the probability that the sum of the spots on the up-faces is 7 or 11
P(A or B) = P(A) + P(B)

The Royal Fruit Company produces two types of fruit drinks. The first type is 65% pure fruit juice, and the second type is 100% pure fruit juice. The
company is attempting to produce a fruit drink that contains 70% pure fruit fuice. How many pints of each of the two existing types of drink must be
used to make 140 pints of a mixture that 70% pure fruit juice?
120 pints of first mixture and 20 pints of second mixture need to make 140 pints new mixture that 70% pure fruit juice.
Let we have to mix existing mixture in x,y respectively in amount to make the new mix of 70% purity.
Given that the first type is 65% pure.
So the pure juice = 65x/100
Given the second type is 100% pure.
So amount of pure juice in it = 100y/100
So the amount of pure juice in new mix = 65x/100+100y/100 = (65x+100y)/100
So the total amount of new mix = x+y
According to question,
((65x+100y)/100)/(x+y) = 70/100
(13x+20y)/(20x+20y) = 7/10
(13x+20y)/(2x+2y) = 7
13x+20y = 14x+14y
14x-13x = 20y-14y
x = 6y
x:y = 6:1
So we have to mix the existing mixture in 6:1 ratio.
So to make 140 pints of new mix need,
first mix = 140*(6/(6+1)) = 140* (6/7) = 120
second mix = 140*(1/(6+1)) = 140*(1/7) = 20
Hence 120 pints of first mixture and 20 pints of second mixture need to make 140 pints new mixture that 70% pure fruit juice.

The proportion statement is 2/3. The missing angles are CK = 12, GN = 15 and GT = 9
How to write the proportion statement and find the missing sides?Given that: Polygon ROCK ~ Polygon GNAT.
The symbol ~ means the polygons are similar to each other. That means the ratios of all their corresponding sides are the same. Thus:
CO/AN = 4/6 = 2/3 (This is the proportion statement)
We can also say CK/AT= 2/3 because the ratios of all their corresponding sides are the same
With this, we can determine the missing sides:
CK/AT= 2/3 where AT = 18
CK/18= 2/3
CK = (18×2)/3 = 12
OR/GN = 2/3 where OR = 10
10/GN = 2/3
2GN = 10×3
2GN = 30
GN = 30/2 = 15
KR/GT = 2/3 where KR = 6
6/GT = 2/3
2GT = 6×3

Now for the red part, we get the length of the rectangle i.e., y = 4.
Area of a rectangle = length * breadth
12 = 4 * x
x = 3.
Hence, the expression would look like
12 + 16 = 4 × (4 + 3)

Based on the given parameters, the amount owed is $10865
How to determine the amount owed in six years?The given parameters about the compound interest are
Principal Amount, P = $5300
Interest Rate, R = 8%
Time, t = 6 years
To calculate the amount owed, we make use of the following formula
A = P + CI
Where
Compound interest, CI = P(1 + R)^t - P
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
In this question, the formula is given as
A = P(1 + r/n)^nt
Where
n = 12, i.e compounded monthly
Substitute the known values in the above equation
A = 5300 * (1 + 8%/12)^(6*12)
Express 8% as decimal
A = 5300 * (1 + 0.08/12)^(6*12)
Evaluate the sum
A = 5300 * (1.01)^(6*12)
Evaluate the exponent
A = 5300 * 2.05
Evaluate the product
A = 10865
Hence, the value of the amount after 6 years is $10865

In this triangle, what is the value of x?
Enter your answer, rounded to the nearest tenth, in the box.
The value of x in this triangle is [tex]67.1^{o}[/tex]
The angle can be calculated as follows:
The first you should calculate the long of the side in front of the angle
as we know [tex]c^{2}= a^{2}+ b ^{2}[/tex]
so [tex]a^{2}= c^{2}- b ^{2}[/tex]
[tex]a =\sqrt{ 72^{2}- 28 ^{2}}[/tex] = 66.3
then we can calculate the angle of the triangle by calculate the sin of x
sin x = [tex]\frac{66.3}{72}[/tex]
sin x = 0.92
x =[tex]\sqrt{0.921}[/tex] = [tex]67.1^{o}[/tex]
hence, The value of x in this triangle is [tex]67.1^{o}[/tex]

^3✓-8x^24 y^36
[tex]\sqrt[3]{-8x^{24}y^{36}} = \sqrt[3]{-8}\cdot \sqrt[3]{x^{24}}\cdot \sqrt[3]{y^{36}}[/tex]
[tex]\sqrt[3]{8}=-2[/tex] because [tex](-2)(-2)(-2)= -8[/tex]
[tex]\sqrt[3]{x^{24}}=x^8[/tex] because [tex](x^8)(x^8)(x^8)=x^{24}[/tex]
[tex]\sqrt[3]{y^{36}}=y^{12}[/tex] because [tex](y^{12})(y^{12})(y^{12})=y^{36}[/tex]
Therefore [tex]\sqrt[3]{-8x^{24}y^{36}} = -2x^8y^{12}[/tex]
Answer:
[tex]-2x^8y^{12}[/tex]
Step-by-step explanation:
Given expression:
[tex]\sqrt[3]{-8x^{24}y^{36}}[/tex]
[tex]\textsf{Apply radical rule} \quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}:[/tex]
[tex]\implies \sqrt[3]{-8}\sqrt[3]{x^{24}}\sqrt[3]{y^{36}}[/tex]
[tex]\textsf{Apply exponent rule} \quad \sqrt[n]{a}=a^{\frac{1}{n}}:[/tex]
[tex]\implies \left(-8\right)^{\frac{1}{3}}\left(x^{24}\right)^{\frac{1}{3}}\left(y^{36}\right)^{\frac{1}{3}}[/tex]
Rewrite 8 as 2³:
[tex]\implies \left(-2^3\right)^{\frac{1}{3}}\left(x^{24}\right)^{\frac{1}{3}}\left(y^{36}\right)^{\frac{1}{3}}[/tex]
[tex]\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:[/tex]
[tex]\implies -2^{\frac{3}{3}}x^{\frac{24}{3}}y^{\frac{36}{3}}[/tex]

Are triangles def and lnm similar if ln equals 5, mn equals 3, de equals 10, and fe equals 6? triangles lnm and def with angles n and e marked with the right angle symbol no, the corresponding sides are not proportional no, the corresponding angles are not congruent yes, by the sss similarity postulate yes, by the sas similarity postulate
The given triangles DEF and LNM are similar "by the SSS similarity postulate"
As given in the question, for LNM:
∠N=90°, LN(base)=5 and MN(prependicular)=3
and for DEF:
∠E=90°, DE(base)=10 and MN(prependicular)=6
Two triangles are similar when all their corresponding angles are congruent.
So far we have ∠N≅∠E=90°
Now, for the remaining angles, we first compare ∠L and ∠D.
From Pythagoras' theorem, we get:
For triangle LNM
[tex]LM^{2}=MN^{2}+LN^{2}\\LM=\sqrt{3^{2}+5^{2}}\\LM=\sqrt{34}[/tex]
For triangle DEF
[tex]DF^{2}=EF^{2}+DE^{2}\\DF=\sqrt{6^{2}+10^{2}}\\DF=\sqrt{136}\\DF=2\sqrt{34}[/tex]
Now we have all sides for both triangles and we compare the ratio of corresponding sides;
Side 1: LN:DE = 5:10 = 1:2
Side 2: MN:FE = 3:6 = 1:2
Side 3: LM:DF = [tex]\sqrt{34}[/tex]:[tex]2\sqrt{34}[/tex] = 1:2
As all three ratios are the same, by SSS similarity postulate, we can deduce that triangles LNM and DEF are similar.
This problem can also be solved with the other two (SAS & AA) similarity postulates.
