Answer:
There is not enough evidence to support the claim that average score for those given colored pen is greater than 77
Step-by-step explanation:
Given the data : 75, 78, 74, 89, 76, 92, 81, 87, 77, 79, 75, 81, 52, 80, 98, 72, 78
Using calculator :
Sample mean, xbar = 79.06
Sample standard deviation = 9.85
Sample size, n = 17
H0 : μ = 77
H1 : μ > 77
The test statistic : (xbar - μ) ÷ (s / sqrt(n))
(79.06 - 77) ÷ (9.85 / sqrt(17))
2.06 ÷ (9.85 / sqrt(17))
= 0.8623
The Pvalue from Tscore :
Pvalue = 0.20063
Since pvaue is > α ; we fail to reject the null ` There is not enough evidence to support the claim that average score for those given colored pen is greater than 77
Answer:
the vertex is of the equation is (3,2)
Answer:
$528.8
Step-by-step explanation:
Given data
Dimension
13 feet by 13 feet
1 ft =4.3 yard
Area= 4.3^2
Area= 18.49 yard
cost of carpet
1 yard= $28.60
18.49 yard= x
cross multiply
x= 18.49*28.60
x=$528.8
Hence the cost to cover the room is $528.8
Answer:
144
Step-by-step explanation:
Since there are 48 fluid-ounce in a cup, we can do 6 x 48
6 x 48 = 288
Now we know how much fluid ounces are in the 6 cups we can divide by the honey bear ( 2 fluid ounce ).
288/2 = 144
Step-by-step explanation:
<em>Here</em><em>,</em>
<em>radius</em><em> </em><em>(</em><em>r</em><em>)</em><em>=</em><em> </em><em>2</em><em>cm</em>
<em>height</em><em>(</em><em>h</em><em>)</em><em>=</em><em>5</em><em>cm</em>
<em>now</em><em>,</em>
<em>according</em><em> </em><em>to the</em><em> </em><em>question</em><em> </em><em>we must</em><em> </em><em>find the</em><em> </em><em>surface</em><em> </em><em>area of cylinder</em><em> </em><em>so</em><em>,</em>
<em>by</em><em> </em><em>formulae</em><em> </em><em>,</em>
<em>a</em><em>=</em><em> </em><em>2.pi.r</em><em>(</em><em>r</em><em>+</em><em>h</em><em>)</em>
<em>now</em><em>,</em><em> </em>
<em>a</em><em>=</em><em> </em><em>2</em><em>×</em><em>3</em><em>.</em><em>1</em><em>4</em><em>×</em><em>2</em><em>(</em><em>2</em><em>+</em><em>5</em><em>)</em>
<em>by</em><em> </em><em>simplifying it we get</em><em>, </em>
<em>The</em><em> </em><em>surface</em><em> </em><em>area of cylinder</em><em> </em><em>is</em><em> </em><em>8</em><em>7</em><em>.</em><em>9</em><em>2</em><em> </em><em>cm</em><em>^</em><em>2</em><em>.</em>
