Solve for w. 8(w+2) = 40

AleksAgata [21]

Answer:

w = 3

Step-by-step explanation:

8 • (w + 2) - 40 = 0

Pulling out like terms :

3.1 Pull out like factors :

8w - 24 = 8 • (w - 3)

Equation at the end of step 3 :

8 • (w - 3) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 8 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : w-3 = 0

Add 3 to both sides of the equation :

w = 3

One solution was found :

w = 3

A group of gymnasts were asked to name their favorite piece of equipment. 0.33 of the gymnasts chose the vault,chose the beam, 0

jolli1 [7]

Answer:

beam, vault, uneven bars, floor

Step-by-step explanation:

The complete question is

A group of gymnasts were asked to name their favorite piece of equipment. 0.33 of the gymnasts chose the vault, 4/9 chose the beam, 0.08 chose the floor exercise, and 1/7 chose the uneven parallel bars. List their choices in order of preference from greatest to least.

step 1

Convert 4/9 and 1/7 to decimals in order to compare with the other values

4/9=0.44

1/7=0.14

step 2

Compare the values

0.44 > 0.33 > 0.14 > 0.08

therefore

The order of preferences from greatest to least is

beam, vault, uneven bars, floor

Simplify sin^2y/sec^2 y−1 to a single trigonometric function

liubo4ka [24]

Answer:

$\frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y$

Step-by-step explanation:

We know that ${ \tan }^{2} y = { \sec }^{2} y - 1$

Also , ${ \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y }$

So ,

$\frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y$

According to the National Telecommunication and Information Administration, 56.5% of U.S. households owned a computer in 2001. W

Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Assuming a binomial distribution for the number of U.S. households that owned a computer in 2001. The formula for binomial distribution is expressed as

P(X = r) = nCr × q^(n - r) × p^r

Where

p = probability of success

q = probability of failure

n = number of sample

From the information given,

p = 56.5% = 56.5/190 = 0.565

q = 1 - p = 1 - 0.565 = 0.435

n = 3

We want to determine P(x greater than or equal to 1). This is also expressed as

1 - P(x lesser than or equal to 1)

P(x lesser than or equal to 1) = P(x = 0) + P(x =1)

P(x = 0) = 3C0 × 0.435^(3 - 0) × 0.565^0 = 0.082

P(x = 1) = 3C1 × 0.435^(3 - 1) × 0.565^1 = 0.32

P(x greater than or equal to 1) = 0.082 + 0.32 = 0.402
