Combine Like Terms :2y+7z-2z+4y+8+y+2

Viktor [21]

Answer:

7y + 5z + 10

Step-by-step explanation:

2y + 7z - 2z + 4y + 8 + y + 2

Like terms are terms that have the same variable part.

2y, 4y, y are like terms (remember that y is the same as 1y when you add)

7z, -2z are like terms

8, 2 are like terms

2y + 7z - 2z + 4y + 8 + y + 2 =

= 2y + 4y + y + 7z - 2z + 8 + 2

= 7y + 5z + 10

How many times dies 11000 go into 609,000

diamong [38]

This is simply 609 000 divided by 11 000

609 000 / 11 000.

Cancel each of the 3 zeros at the top and bottom

= 609/11

Use a calculator

= 55.3636...

So it goes in approximately 55.36 times.

Each year the US Environmental Protection Agency (EPA) releases fuel economy data on cars manufactured in that year. Below arc s

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attachment file.

$n_1 = 26 \\\\ x_1 = 16.12 \\\\s_1 = 3.58\\\\n_2 = 26\\\\ x_2 = 19.85 \\\\ s_2 = 4.51$

$H_0: u_1 = u_2\\\\H_1: u_1 \neq u_2$

Using formula:

$\to S^{2}_{p}=\frac{S^{2}_{1}(n_1 -1)+ S^{2}_{2}(n_2-1)}{n_1+n_2-2}$

$\to Sp^2 = \frac{((26-1) \times (3.58^2) + (26-1) \times (4.51^2))}{(26+26-2)}$

$= \frac{((25) \times 12.8164 + (25) \times 20.3401 )}{(26+24)}\\\\ = \frac{(320.41 + 508.5025)}{(50)}\\\\ = \frac{(828.9125)}{(50)}\\\\=16.57825$

$\to Sp = 4.0716$

Calculating the value of standard error:

$\to SE = Sp \times \sqrt{\frac{1}{n_1}+\frac{1}{n_2}}$

$=4.0716 \times \sqrt{\frac{1}{26}+\frac{1}{26}}\\\\=4.0716 \times \sqrt{\frac{1+1}{26}}\\\\=4.0716 \times \sqrt{\frac{2}{26}}\\\\=4.0716 \times \sqrt{\frac{1}{13}}\\\\=4.0716 \times 0.277 \\\\=1.1278332\\\\= 1.1293$
