The claim is that the standard deviation of the speeds of drivers in Bradford is 8 mph. An experienced driver feels that this is
Irina-Kira [14]

Answer:

Null hypothesis is rejected. Standard deviation is > 8 miles per hour

Step-by-step explanation:

σ [Population standard deviation] = 8 , s [sample standard deviation] = s

n [no of items] = 8

H0 [Null] : σ = 8 ; H1 [Alternate - Right Tail] : σ > 8

χ2 = (n - 1) . s^2 / σ^2

= 49 x (10.5)^2 / 82 = 5402.25 / 64

χ2 = 84.410

df [degree of freedom] = n -1 = 50 - 1 = 49

P value (χ^2 49 > 84.410) = 0.00125

p = 0.0013

p < α ie 0.05

So, H0 is rejected

Hence we state that standard deviation is > 8 miles per hpur

Claudia added an equilateral triangle shape that is one inch high and one inch wide to a slide in her presentation. She clicked
mr_godi [17]

The effect of Claudia's changing the height of of the triangle from 1 inch

to 3 inches is the option;

  • The height of the triangle changed to three inches but the width remained 1 inch

<h3>Which option gives the effect of changing the height?</h3>

The given dimensions of the equilateral triangle Claudia added are;

Height of the triangle = 1 inch

Width of the triangle = 1 inch

The value Claudia typed in the Shape Height box = 3

Required:

What happened to the shape after she press Enter

Solution:

By entering 3 in the Shape Height box, changes the height of the

equilateral triangle to 3 inches but the width remains 1 inches

From a similar question posted online, the correct option is therefore;

  • The height of the triangle changed to three inches but the width remained 1 inch

Allushta [10]

Answer:

(4, -2)

Step-by-step explanation:

if you do process of elimination you find that 'a' doesn't work out but 'b' will . . . substitute -2 for 'y' and 4 for 'x' and see if the equation is true

-2 = -3/4(4) + 1

-2 = -3 + 1

-2 = -2

The world’s largest round pizza was set in December 2012 by five Italian chefs. The diameter of this pizza was 131 feet. If this
Tems11 [23]

First find the area of the whole pizza.

The formula for area of a circle is Area = PI x r^2

The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet.

I will use 3.14 for PI since the problem doesn't say what value to use.


Area = PI x 65.5^2

Area = 3.14 x 4290.25

Area = 13,471.39 square feet


Divide the total area by the number of pieces:

13,471.39 / 50 = 269.43 square feet


To find the length of the crust first find the circumference of the whole pizza:

Circumference = PI x diameter

Circumference = 3.14 x 131 = 411.34 feet

Now divide the total by the number of pieces:

411.34 / 50 = 8.23 feet


Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.
