Step-by-step explanation:

The y-intercept of the graph represents the beginning price of the candy is $8. Which is the correct answer would be option (A).

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The general equation of a line is y = mx + c

where m is the slope of the line and c is the intercept.

A linear equation is defined as an equation in which the highest power of the variable is always one.

We have to determine the y-intercept of the graph about the price of the bag of candy.

Kroger priced a certain bag of candy at $8. After 1 day, the candy was marked down to $6.

According to the given graph,

Here, the y-intercept of the graph represents the beginning price of the candy is $8.

Therefore, the correct answer would be option (A).

C, every 5th student entering the school.

This would provide the least biased answer by the chances, it would not be skewed as my boy Gabe is asking random people that are spread out rather than simply everyone on his soccer team (if there is a connection between enjoying pizza and playing soccer) or asking everyone in the cafeteria, as similar people may sit together. It’s all in the chances.

Question:

Gabriel wants to know which pizzeria is most popular with students at his school. Which group of students should Gabriel survey in order to get the most accurate results?

Answer:

C. Every 5th person entering the school.

Step-by-step explanation:

A. All the boys in the cafeteria. This is incorrect because they would only add up to 1. The boys. And 2. Only the boys inside of the cafeteria. So that not even counting the ones that are still in the classrooms or in the bathrooms. so therefore A is incorrect.

B. All the students on his soccer team. This would not add up to much because lets say there are 10 players on his soccer team and over 100 people in his school, that would only make up 10% of his whole school, so obviously, B. Is also incorrect.

D. Every 5th person entering Daniella's Pizzeria. This is incorrect also because Gabriel wants to know which pizzeria is most popular in his school, this answer does not say anything about his school, it only says which pizzeria and how many people. In answer D. It says Every 5th person entering Daniella's Pizzeria. This answer already says which pizzeria he would be going to so that part is already proof that D is incorrect.

C. Every 5th person entering the school. This is correct beause it explains how he would be asking every 5th person entering the school. So lets say most of the people he tallied likes Daniella's Pizzeria the most. There would be a tally poll that I have shown in the picture. (Sorry that its messy I did that on mouse.) and as you see in green it says that more people like Daniella's Pizzeria more than any others. So now Gabriel has his results, so now he knows which pizzeria to go to.

Answer:

B

Step-by-step explanation:

A = 0.5kg (Not close)

B = 0.05

C = 0.02 ( Not close)

D = 0.04

(Explanation why answer is B and not D)

B is closet because even we round off to two decimal places 0.05kg answer comes not 0.04kg

Plus 0.05 is 0.01kg away from 0.049, While 0.04kg is 0.09kg away from 0.049kg.

I hope my answer helps you.

1/20 kg is closest to 0.049 kg among the given choices. So, correct option is B.

To determine which option is closest to 0.049 kg, we can compare the given options to the target value and find the option with the smallest absolute difference.

A. ½ kg = 0.5 kg (Difference = |0.5 kg - 0.049 kg| ≈ 0.451 kg)

B. 1/20 kg = 0.05 kg (Difference = |0.05 kg - 0.049 kg| = 0.001 kg)

C. 1/50 kg = 0.02 kg (Difference = |0.02 kg - 0.049 kg| ≈ 0.029 kg)

D. 2/50 kg = 0.04 kg (Difference = |0.04 kg - 0.049 kg| = 0.009 kg)

Comparing the absolute differences, we can see that option B (1/20 kg = 0.05 kg) has the smallest difference from 0.049 kg, which is only 0.001 kg.

Therefore, option B (1/20 kg) is closest to 0.049 kg among the given choices.

When dealing with questions like this, it is helpful to compare the values using the absolute difference from the target value. The option with the smallest absolute difference is the closest approximation to the target value. In this case, 1/20 kg provides the closest value to 0.049 kg, making it the correct choice.

Explanation:

"There are, however, three words in geometry that are not formally defined. These words are point, line and plane, and are referred to as the 'three undefined terms of geometry'"

If point, line, and plane are all undefined terms in Euclidean geometry, then that only leaves one answer left, c. bisector.

The p-value can be calculated to test the null hypothesis that the average running time of HP laptops is 120 minutes against the alternative hypothesis that it is not equal to 120 minutes.

The p-value for testing the hypothesis that the average time for the HP laptops is not equal to 120 minutes can be calculated using a t-test. Given a sample mean of 122 minutes, a sample size of 60, a null hypothesis mean of 120 minutes, and a standard deviation of 25 minutes, we can calculate the t-value and find the corresponding p-value.

To calculate the t-value, we use the formula: t = (sample mean - null hypothesis mean) / (sample standard deviation / sqrt(sample size))

Plugging in the values, we get: t = (122 - 120) / (25 / sqrt(60))

Calculating the t-value, we find t ≈ 0.894

To find the p-value associated with this t-value, we can refer to a t-distribution table or use statistical software. The p-value represents the probability of observing a t-value as extreme as the one obtained, assuming the null hypothesis is true.

Since the p-value (0.757) is greater than the commonly used significance level of 0.05, we fail to reject the null hypothesis. This suggests that there is not enough evidence to conclude that the average running time of HP laptops is significantly different from 120 minutes.

The inverse of the statement consist in the negation fo the two parts of the statement, then:

We can rewrite the stament as: If an angle is obtuse, then it is not a right angle.

The first part of the statement says "if an angle is obtuse", then the negation is "if an angle is not obtuse".

The other parts says "then it is not a right angle", the negation is "then it is a right angle"

Then, the inverse of the statement says: If an angle is not obtuse, then it is a right angle.

By definition, an obtuse angle is an angle that measures more than 90° but less than 180°. And a right angle is an angle that measures exactly 90°. But there's also acute angles, which measures less than 90°, and other classifications for angles.

Thus, if an angle is not obtuse, it can be a right angle but also can be an acute angle, or even a straight angle or reflex angle.

In conclusion, the statement: If an angle is not obtuse, then it is a right angle, is FALSE.

Answer:It will take 5 sec for a parachute to open.I did it on a piece of paper for u to show u more information

Step-by-step explanation:

Solving quadratic equation 16 t² -60t -100=0 formed by Projectile Motion Formula and given conditions it is found that it takes t = 5 seconds to fall from 1000 feet to 900 feet before the parachute opens.

Quadratic equation is an equation which contains one unknown variable and the highest power of this unknown variable is 2. Let x be the unknown variable then the standard quadratic equation in x is given by

ax²+bx+c =0, where a, b, c are constants and a≠0

We can solve this equation by factorizing ax²+bx+c and  putting those factors equal to zero to solve for x.

Projectile Motion Formula h = -16 t² + v t + s,

where t = time in seconds

h = height of the projectile

v = initial velocity

s= starting height of fall

Given s = 1000 feet, v= 60 feet per second, h = 900 ft

And t we have to find.

Projectile motion equation becomes:

900 = -16 t² + 60 t + 1000

⇒16 t² -60t + 900-1000=0

⇒16 t² -60t -100=0, which is a quadratic equation in variable t

Factorizing this quadratic equation

⇒ 16t² - 80t + 20t -100 =0

⇒16t(t -5) + 20( t - 5 ) =0

⇒ (16t +20) ( t-5)=0

Putting these factors equal to zero

16t +20 =0 ⇒ t = -20/16, which is neglected as time cannot be negative.

t-5 = 0⇒ t =5

Therefore it takes 5 seconds to fall from 1000 feet to 900 feet before the parachute opens.
