In 3-10 use the distributive property to find each missing factor
Elanso [62]

The missing factor in the equation is -21

<h3>What is a distributive factor?</h3>

The Distributive Property introduces the multiplication operator an existing mathematical statement that involves the addition operator.

From the complete question, the equation is given as:

6 \times x= (3 \times 7) + (x \times 7)

Where x represents the missing factor.

So, we have:

6x= (21) + (7x)

Remove brackets

6x= 21 + 7x

Collect like terms

6x-7x= 21

Evaluate the like terms

-x= 21

Divide both sides by -1

x= -21

Hence, the missing factor in the equation is -21

An automobile manufacturer has given its van a 47.2 miles/gallon (MPG) rating. An independent testing firm has been contracted t
Romashka-Z-Leto [24]

Answer:

Test statistic = 1.664

Step-by-step explanation:

The hypothesis :

H0 : μ = 47.2

H1 : μ ≠ 47.2

Given that :

Sample mean, xbar = 47

Sample size, n = 250

Standard deviation, σ = 1.9

The test statistic :

(xbar - μ) ÷ (σ/√(n))

T = (47 - 47.2) ÷ (1.9/√(250))

T = (0.2 / 0.1201665)

Test statistic = 1.664
