In a line of students, Jenna is number 8.The teacher says that a rule for a number pattern is add 4. The first student inline says the first term, 7. What number should Jenna say?

Answers

Answer:

Formula for nth term in Arithmetic sequences is:

a_n =a+(n-1)d

where a is the first term, d is the common difference and n is the number of terms.

As per the statement:

The rule for the pattern is add 4.

As the first term in line says the first term i,e 7

a= 7

common difference(d)= 7

As the Jenna number is 8th in line.

Series we get;

7, 11, .........a_8

We have to find the 8th term.

n = 8, a = 7 and d = 4

Using above formula:

a_8 = 7+(8-1)4 = 7+7 \cdot 4 = 7 +28 = 35

Therefore, 35 number should Jenna say.

7 , 11 , 15,19,23,27,31,35. Jenna should say 35.

If 14 people feeds on 3 cups of rice. how much rice feeds 17 people

Answers

The answer is:

17*(3/14)

More detailed;

3/14 gives us how many it takes to feed 1 person, then we times the amount it takes to feed one person by 17 (to get 17 people)
3.6 cups <br />dividing 3 by 14 gives you the answer for each person then just times by 17.

What is the value for quartile 3(Picture Included) please explain

Answers

Interquantile range (IQR) is represented by the gray box.
IQR = Q3 - Q1  //range for 50% middle values (of all values in the data)
thus Q1 is left side of the gray box, Q3 is right side of the gray box
Q1 = 8  //25% values are less or equal than Q1
Q3 = 18  //25% values are more or equal than Q3
answer: Q3 = 18

Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red. The other half were black. Josh predicted that he would choose a red card in 4 out of 8 trials. When he conducted the experiment, he actually chose a red card 6 out of 8 times. Which explains the most likely reason for the discrepancy between Josh’s predicted and actual results?A.He incorrectly predicted the number of times he would choose a red card.
B.He incorrectly determined the actual number of times he chose a red card.
C.He used too few trials for the sample space.
D.He used too many trials for the sample space.

Answers

Answer: C. He used too few trials for the sample space.


Step-by-step explanation:

Given: Josh used a standard deck of 52 cards to conduct an experiment.

As half of the cards in the deck were red.

If we take sample space= 52 cards

Then probability of getting a red card=(1)/(2)

But Josh took 8 cards as sample space which is not enough for the sample space.

therefore, C. is the right answer. "He used too few trials for the sample space."


Answer:

Option C - He used too few trials for the sample space.

Step-by-step explanation:

Given: Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red. The other half were black.

Josh predicted that he would choose a red card in 4 out of 8 trials.

When he conducted the experiment, he actually chose a red card 6 out of 8 times.

To find : Which explains the most likely reason for the discrepancy between Josh’s predicted and actual results?

Solution :

Sample space = 52 cards

As half of the cards in the deck were red.

Probability of getting a red card is (1)/(2)

He predict and conduct to choose a red card out of 8 trials which is not enough for the sample space.

Therefore, Option C is correct.

He used too few trials for the sample space.

Factor 6x2 - 33x + 15

Answers

Answer:

Step-by-step explanation:

6x² -33x + 15 =6x² -30x - 3x + (-3)*(-5)

=6x(x - 5) - 3(x - 5 )

=(x-5) (6x-3)

Answer:

3(2x - 1)(x - 5).

Step-by-step explanation:

6x2 - 33x + 15

= 3(2x^2 - 11x + 5)

= 3(2x - 1)(x - 5).
