Which equation represents a line which is parallel to the line y=5/6x−7?
lyudmila [28]

Answer:  The choice will be any equation where the slope is the same and the y-intercept is different.

y=\frac{5}{6}x + b

Step-by-step explanation:  Using slope-intercept form, y = mx + b,

m is the slope, b is the y-intercept.

Parallel lines will have the same slope.

So, you are looking for another equation that has 5/6 as the coefficient of x.

It could be an equation in the form 6y + 5x = _b_ where the constant, b, could be anything except -42, as that would be an identical line, not parallel.

mina [271]

Complete Question

An F5 tornado is classified as having mean wind speeds greater than 261 mph. In an effort to classify a recent tornado, 20 wind speed measurements were randomly selected from within the path of the tornado. Suppose the mean wind speed for this tornado really is greater than 261 mph with a sample standard Deviation 41.09 mph. Based on the data, if we fined little to no evidence against the null hypothesis that the mean wind speed is 261 mph, we have made _______________.

Answer:

P-value=0.3322

Step-by-step explanation:

From the question we are told that:

Sample size n=20

Population mean N=261  

Sample mean \=x= 265.1  

Sample standard deviation \sigma=41.09    

Generally the equation t test statistics is mathematically given by

t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }

t=\frac{265.1-261}{\frac{41.09}{\sqrt{20} } }

t=0.446

Therefore

Pvalue from table is

P-value=0.3322

James measured a piece of construction paper to be 6 3/4 inches wide and 9 2/3 inches long. What is the area of the piece of con
ivolga24 [154]

Answer:

The area of the piece of construction paper is \frac{261}{4} inches^2

Step-by-step explanation:

Length of construction paper =6 \frac{3}{4} inches

                                                 =\frac{27}{4} inches

Width of construction paper = 9 \frac{2}{3} inches

                                              = \frac{29}{3} inches

Area of construction paper =Length \times Width

Area of construction paper = \frac{27}{4}  \times \frac{29}{3}

                                             = \frac{261}{4} inches^2

Hence the area of the piece of construction paper is \frac{261}{4} inches^2
