How many metres are there in one and three quarter killometres

Mathematics

jolli1 [7]3 years ago
3 0
We know there are 1000 meters in 1 kilometer, KILO=1000.

so, how many in 3/4 km?

\bf \begin{array}{ccll}
meter&km\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1000&1\\\\
m&\frac{3}{4}
\end{array}\implies \cfrac{1000}{m}=\cfrac{1}{\frac{3}{4}}\implies \cfrac{1000}{m}=\cfrac{\frac{1}{1}}{\frac{3}{4}}\implies \cfrac{1000}{m}=\cfrac{1}{1}\cdot \cfrac{4}{3}
\\\\\\
\cfrac{1000}{m}=\cfrac{4}{3}\implies \cfrac{1000\cdot 3}{4}=m

How to do exterior angle
SVETLANKA909090 [29]
The exterior angles of a polygon all add to 360, if you need to find an exterior angle when given the number of sides and that all angles are equal you simply do: 360/ number of sides.
When you need to find the exterior angle when given an interior angle, you do: 180- interior angle.

Hope this helps :)

Suppose you are the manager of Speedy Oil Change which claims that it will change the oil in​ customers’ cars in less than 30 mi
Veronika [31]

Answer:

Explained below.

Step-by-step explanation:

(1)

The hypothesis can be defined as follows:

<em>H</em>₀: The Speedy Oil Change will change the oil in​ customers’ cars in more than 30 minutes on average, i.e. <em>μ</em> > 30.

<em>H</em>ₐ: The Speedy Oil Change will change the oil in​ customers’ cars in less than 30 minutes on average, i.e. <em>μ</em> ≤ 30.

(2)

Use Excel to compute the sample mean and standard deviation as follows:

\bar x=\text{AVERAGE(array)}=24.917\\\\s=\text{STDEV.S(array)}=8.683

Compute the test statistic as follows:

t=\frac{\bar x-\mu}{s/\sqrt{n}}=\frac{24.917-30}{8.683/\sqrt{36}}=-3.51

The degrees of freedom is:

df = n - 1

   = 36 - 1

   = 35

Compute the p-value as follows:

p-value=P(t_{35}

(3)

The <em>p</em>-value = 0.0006 is very small.

The null hypothesis will be rejected at any of the commonly used significance level.

(4)

There is sufficient evidence to support the claim that the Speedy Oil Change will change the oil in​ customers’ cars in less than 30 minutes on average.
