Answer:
B). Angle G is smaller than Angle P
Step-by-step explanation:
Given that,
GK ≅ PN,
GH ≅ MP
HK = 32 cm
MN = 40cm
and the other lengths are congruent.
This suggests that although the triangles are congruent yet they are not similar. Hence, the second statement correctly compares the angles that 'angle P is greater than angle G.'

The reflection of a horizontal line has the same result as a rotation of 90 degrees clockwise.
Step-by-step explanation:
When an image is rotated 90 degrees counterclockwise the shape is still congruent but in a different quadrant. The same is true when an image is reflected across a horizontal line.
Native people in the Amazon Rainforest use a toxin to help them catch fish. The toxin interferes with the gas exchange in the fish which makes them slow and easy to catch. Which of the following describes what is occurring to the cellular respiration in the fish?
A . The fish are unable to take in oxygen and cannot convert glucose into ATP
B. The fish are unable to take in ATP and cannot produce glucose for energy
C. The fish are unable to make glucose from sunlight
D. The fish are unable to take in carbon dioxide and cannot make ATP
Answer:
A
Step-by-step explanation:
The thing that will occur to the cellular respiration in the fish is A. The fish are unable to take in oxygen and cannot convert glucose into ATP.
Cellular respiration refers to the metabolic pathway that helps in the breaking down of glucose and the production of ATP.In this case, since there is toxin that is put in the river to help them catch fish, the fish will be unable to take in oxygen and would not be able to convert glucose into ATP.Read related link on:

The amount of time required for an oil and filter change on an automobile is normally distributed with a mean of 45 minutes and a standard deviation of 10 minutes. 1)If a random sample of 16 cars is selected, a) what is the probability that the sample mean will be between 39 and 48 minutes? b) 95% of all sample means will fall between what two values? c) 90% of the sample means will be greater than what value? 2)What sample size is needed in order for the standard deviation of the mean to be one fifth of the population standard deviation?
Answer:
1a
[tex]P(39 < X < 48 ) = 0.8767[/tex]
1b
95% of all sample means will fall between [tex] 40.1 < \mu < 49.9 [/tex]
1c
[tex]\= x = 41. 795[/tex]
2
[tex]n = 25[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]n = 45[/tex]
The population standard deviation is [tex]\sigma = 10[/tex]
The sample size is n = 16
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{x} = \frac{ \sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{ 10 }{\sqrt{16 } }[/tex]
=> [tex]\sigma_{x} = 2.5[/tex]
Generally the probability that the sample mean will be between 39 and 48 minutes is
[tex]P(39 < X < 48 ) = P( \frac{ 39 - 45}{ 2.5} < \frac{X - \mu }{\sigma } < \frac{ 48 - 45}{ 2.5} )[/tex]
=> [tex]P(39 < X < 48 ) = P(-2.4 < Z< 1.2 )[/tex]
=> [tex]P(39 < X < 48 ) = P( Z< 1.2 ) - P(Z < -2.4)[/tex]
From the z table the area under the normal curve to the left corresponding to 1.2 and -2.4 is
=> [tex]P( Z< 1.2 ) = 0.88493[/tex]
and
[tex]P( Z< - 2.4 ) = 0.0081975[/tex]
So
[tex]P(39 < X < 48 ) = 0.88493 -0.0081975[/tex]
=> [tex]P(39 < X < 48 ) = 0.8767[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.96 * 2.5 [/tex]
=> [tex]E =4.9 [/tex]
Generally the 95% of all sample means will fall between
[tex]\mu -E < and \mu +E[/tex]
=> [tex]45 -4.9\ and \ 45 + 4.9[/tex]
Generally the value which 90% of sample means is greater than is mathematically represented
[tex]P( \= X > \= x ) = 0.90[/tex]
=> [tex]P( \= X > \= x ) = P( \frac{\= X - \mu }{ \sigma_x} > \frac{\= x -45 }{ 2.5} ) = 0.90[/tex]
=> [tex]P( \= X > \= x ) = P( Z > z ) = 0.90[/tex]
Generally from the z-table the critical value of 0.90 is
[tex]z = -1.282[/tex]
[tex]\frac{\= x -45 }{ 2.5} = -1.282[/tex]
=> [tex]\= x = 41. 795[/tex]
Considering question 2
Generally we are told that the standard deviation of the mean to be one fifth of the population standard deviation, this is mathematically represented as
[tex]s = \frac{1}{5} \sigma[/tex]
Generally the standard deviation of the sample mean is mathematically represented as
[tex]s = \frac{\sigma }{ \sqrt{n} }[/tex]
=> [tex]\frac{1}{5} \sigma = \frac{\sigma }{ \sqrt{n} }[/tex]
=> [tex]n = 5^2[/tex]
=> [tex]n = 25[/tex]
Using the normal distribution and the central limit theorem, it is found that:
1)
a) 0.8767 = 87.67% probability that the sample mean will be between 39 and 48 minutes.
b) 95% of all sample means will fall between 40.1 and 49.9 minutes.
c) 90% of the sample means will be greater than 41.8 minutes.
2) A sample size of 25 is needed.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
The mean is of 45 minutes, hence [tex]\mu = 45[/tex].The standard deviation is of 10 minutes, hence [tex]\sigma = 10[/tex].Sample of 16 cars, hence [tex]n = 16, s = \frac{10}{\sqrt{16}} = 2.5[/tex].Item 1, question a:
The probability is the p-value of Z when X = 48 subtracted by the p-value of Z when X = 39, hence:
X = 48:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{48 - 45}{2.5}[/tex]
[tex]Z = 1.2[/tex]
[tex]Z = 1.2[/tex] has a p-value of 0.8849.
X = 39:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{39 - 45}{2.5}[/tex]
[tex]Z = -2.4[/tex]
[tex]Z = -2.4[/tex] has a p-value of 0.0082.
0.8849 - 0.0082 = 0.8767
0.8767 = 87.67% probability that the sample mean will be between 39 and 48 minutes.
Item b:
The critical value for a 95% confidence interval is |z| = 1.96, hence:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]-1.96 = \frac{X - 45}{2.5}[/tex]
[tex]X - 45 = -1.96(2.5)[/tex]
[tex]X = 40.1[/tex]
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]1.96 = \frac{X - 45}{2.5}[/tex]
[tex]X - 45 = 1.96(2.5)[/tex]
[tex]X = 49.9[/tex]
95% of all sample means will fall between 40.1 and 49.9 minutes.
Item c:
Greater than the 10th percentile, which is X when Z has a p-value of 0.1, so X when Z = -1.28.
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]-1.28 = \frac{X - 45}{2.5}[/tex]
[tex]X - 45 = -1.28(2.5)[/tex]
[tex]X = 41.8[/tex]
90% of the sample means will be greater than 41.8 minutes.
Item 2:
This is n for which [tex]s = \frac{10}{5} = 2[/tex], hence:
[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]2 = \frac{10}{\sqrt{n}}[/tex]
[tex]2\sqrt{n} = 10[/tex]
Simplifying both sides by 2:
[tex]\sqrt{n} = 5[/tex]
[tex](\sqrt{n})^2 = 5^2[/tex]
[tex]n = 25[/tex]
A sample size of 25 is needed.

Answer:
AStep-by-step explanation:
Exponents are representations of repeated multiplication.
For example: 5³ = 5 x 5 x 5 or 125. If we want to compare values, we must evaluate each expression and then compares the final values for each.
3⁶ = 3 x 3 x 3 x 3 x 3 x 3 = 729
6³ = 6 x 6 x 6 = 216
729 > 216
We can immediately notice that 3⁶ is much larger than 6³
what is baal veer? give all the bad and good fairies names i will mark those people as b brainiest
Answer:
The story revolves around a boy, Baal Veer, who is blessed with the powers of 7 fairies. Gaal Pari (Cheek Fairy), Vijhdar Pari (Electric Fairy), Baal Pari (Tress Fairy), Atkaati Pari (Obstacle Fairy), Aarpar Pari (Across Fairy), Bhatkati Pari (Wander Fairy), Natkhat Pari (Naughty Fairy) and Rani Pari (Queen Fairy) give magical powers to Baal Veer to help them fight an evil fairy Bhayankar Pari (Frightening Fairy), who wants to become the queen of Pari Lok (Fairy Realm). Years ago, Maa Pari (Mother Fairy) gave Pari Lok's (Fairy Realm's) throne to Bahuroopi Pari (Disguise Fairy) instead of Bhayankar Pari, who, at that time was Bhali Pari (Good Fairy), so she returns to take revenge from Maa Pari and Rani Pari. Baal Veer is sent to Earth to help children and to save Earth from Bhayankar Pari and the wrath of other cunning and cruel, evil fairies. Baal Veer stays with the Dagli family on Earth as Ballu. The family has seven members who never lie, even at the time of difficult circumstances, including Manav and Meher, who later receive powers from Rani Pari (they were made Baal Mitra and Baal Sakhi, respectively) and help Baal Veer in his quests and adventures.
