Answer:

a. Firat term of the sequence= 77

b. 29th term of the sequence= -35

c. Sum of the first 40 terms of the sequence= -40

Step-by-step explanation:

The first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.

Given that, [tex]a_{15} =21[/tex] and d=-4.

The nth term of the arithmetic sequence is [tex]a_{n} =a+(n-1)d[/tex].

To find the first term of the sequence:

[tex]a_{15}[/tex]=a+(15-1)(-4)

⇒21=a+(15-1)(-4)

⇒a=77

To find the 29th term of the sequence:

[tex]a_{29}[/tex]=77+(29-1)(-4)=-35

To find the sum of the first 40 terms of the sequence:

The first n terms of a sequence [tex]=\frac{n}{2}[2a+(n-1)d)][/tex]

[tex]S_{40} =\frac{40}{2}[2 \times77+(40-1)(-4))][/tex]

=20(154-156)=-40

Therefore, the first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.

Answer:

answer: 31.4

Step-by-step explanation:

the formula to finding circumference is just diameter × pi we arent given the diameter so we have to figure it out but what we do know is the radius is half of the diameter so 5 x 2 = 10 so now that we have the diameter we just multiply by pi so 10 × 3.14 = 31.4 Hope this helps!

Answer:

10 π m

Step-by-step explanation:

Given,

Radius ( circle ) = 5 m

To find : Circumference ( circle ) = ?

Formula : -

Circumference ( circle ) = 2πr

Circumference ( circle )

= 2 x π x 5

= 10 π m

x > 4 hours/week

4 hours is 240 minutes

45 minutes/ 1st book

4 hours minus 45 minutes is 3 hours and 15 minutes

3 hours and 15 minutes = 195 minutes

195 minutes ÷ 6 = 32.5 minutes

make the formula working backwards

(240 - 45) ÷ 6 > x

Step-by-step explanation:

Answer:

x = number of pairs of sandals sold = 287

Total pair of sneakers and sandals sold = 451 pairs

Step-by-step explanation:

Sneakers = 4

Sandals = 7

Sneakers : sandals = 4 : 7

If the store sells 164 pair of sneakers

Let

x = number of pairs of sandals sold

Sneakers : sandals = 164 : x

Equate both ratios to find x

4 : 7 = 164 : x

4/7 = 164/x

4 * x = 7 * 164

4x = 1,148

x = 1,148/4

x = 287

x = number of pairs of sandals sold = 287

how many pair of sneakers and sandals does the store sell in all ?

Total pair of sneakers and sandals sold = Sneakers + sandals

= 164 + 287

= 451 pairs

Total pair of sneakers and sandals sold = 451 pairs

Answer: A

Step-by-step explanation:

I did this test before : )

The theoretical probability of pulling a blue pen based on the expected frequency will get closer to 1/2 as the no. of trials increases.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The first thing is to define each of the probabilities,

Theoretical probability is defined as a proportion that expresses the ways to be successful in the total events of an experiment.

Experimental probability is defined as the proportion of the proposed result for the number of experimental attempts.

Based on the above explanation, the reason that best supports is that; the more the experiment is repeated, the closer the experimental probability gets to the theoretical one, However, as the number of attempts increases, it tends to go more to what theoretically is what would happen.

The more experiments that are done, the more the theoretical attempts trend is marked

Hence, the Theoretical probability of pulling a blue pen based on the expected frequency will get closer to 1/2 as the no. of trials increases.

Step-by-step explanation:

Wages are usually identified as the money you are paid per hour. For instance, the current minimum wage in the United States, meaning the least per hour an employer can pay a worker, is $7.25 an hour. Minimum wage is determined by the Federal Department of Labor. Individual states can set a higher minimum wage for its citizens. In those instances where the federal and state minimum wages are different, the higher minimum wage is used.

Answer:

2 • (u - 2) • (u2 + 2u - 7)

Step-by-step explanation:

2.1     Pull out like factors :

  2u - 4  =   2 • (u - 2)  

Trying to factor by splitting the middle term

2.2     Factoring  u2 + 2u - 7  

The first term is,  u2  its coefficient is  1 .

The middle term is,  +2u  its coefficient is  2 .

The last term, "the constant", is  -7  

Step 1: Multiply the coefficient of the first term by the constant   1 • -7 = -7  

Step 2: Find two factors of  -7  whose sum equals the coefficient of the middle term, which is   2 .

     -7 +   1 =   -6  

     -1  +   7 =   6
