Answer:

Jaw saw an average of 6 birds each day

Step-by-step explanation:

Given: One day, Jean saw 7 birds. The next day, she saw 11 birds. The next day, she saw no birds.

To find: average number of birds Jean saw each day

Solution:

Average is a central value of a set of terms.

Average of terms $x_1,x_2,x_3,...,x_n$ is given by $\frac{x_1+x_2+x_3+...+x_n}{n}$

Number of birds, Jean saw on day one $(x_1)$ = 7

Number of birds, Jean saw on the second one $(x_2)$ = 7

Number of birds, Jean saw on the third one $(x_3)$ = 7

So,

average number of birds Jean saw each day = $\frac{x_1+x_2+x_3}{3} =\frac{7+11+0}{3}=\frac{18}{3}=6$

Therefore,

Jaw saw an average of 6 birds each day

Write the first five terms of the sequence defined by the explicit formula

denis-greek [22]

<u>Answer:</u>

The correct answer option is: 19, 13, 3, -11, -29.

<u>Step-by-step explanation:</u>

We are given the following explicit formula for an arithmetic sequence:

$a_n=21-2n^2$

So to find the first five terms of this sequence, we will substitute the values of $n$ (num here in the given formula:

$a_1=21-2(1)^2\\\\a_1=19$

$a_2=21-2(2)^2\\\\a_2=13$

$a_3=21-2(3)^2\\\\a_3=3$

$a_4=21-2(4)^2\\\\a_4=-11$

$a_5=21-2(5)^2\\\\a_5=-29$

Therefore, the first five terms of the sequence defined by the explicit formula $a_n=21-2n^2$ are 19, 13, 3, -11, -29.

10x +7 = -3х – 3 help guys

Pepsi [2]

Answer:

x = -10/13

Step-by-step explanation:

10x + 7 = -3x - 3

Add 3x to both sides

10x + 3x + 7 = -3x + 3x - 3

13x + 7 = 0x - 3

13x + 7 = -3

Subtract 7 from both sides

13x + 7 - 7 = -3 - 7

13x + 0 = -10

13x = -10

Divide both sides by 13

13x ÷ 13 = -10 ÷ 13

1x = -10/13

x = -10/13

Help please guys!!!!

leva [86]

Answer:

they are like terms

Step-by-step explanation:

the sign ± is not a matter only veriable and power

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

Leona [35]

Answer:

$33.33

Step-by-step explanation:

We are told in the above :

WalMart offered a 15% discount off the regular price of a Ice Cream Maker.

The amount of the discount is $5.00.

The formula for Percentage Discount =

Discount/Original amount × 100

Original amount = x

Hence:

$5/x × 100 = 15%

= 5/x = 15/100

Cross Multiply

5 = 0.15 × x

5= 0.15x

x = 5/0.15

x = $33.33

Therefore, the regular price of the Ice Cream Maker is $33.33
