If the mean of the data set is 35 apples find the number of apples on the Granny Smith tree

alisha [4.7K]

Answer:

$N=\frac{\sum x_{i} }{35}$

Step-by-step explanation:

Given

The mean of the data set is 35 apples.
Let's call $N$ the number of apples.

The means is defined as the quotient between the sum of all elements and the total number.

Mathematically, it would be defined as

$x=\frac{\sum x_{i} }{N}$

But, we know that the mean is equal to 35.

$35=\frac{\sum x_{i} }{N}$

Then, we solve for $N$

$N=\frac{\sum x_{i} }{35}$

As you can see, the total number of apples depends on the sum of all elements of the data set.

For example, if the sum of all elements is 700, the total number of apples would be

$N=\frac{700}{35}=200$

Therefore, the expression that represents the total number of apples is

$N=\frac{\sum x_{i} }{35}$

In the triangle below, y= . Round to the nearest tenth

horsena [70]

Use cosine.

$cosine={adjacent}{hypotenuse}$

We have:

adjacent = 9cm and hypotenuse = 17 cm

$\cos x=\dfrac{9}{17}\approx0.5294\to x\approx58^o$

Layna can paint a 350-square foot room in 4 hours. It takes Bebe 7 hours to paint the same room. Which equation can be used to f

ohaa [14]

The equation can be used to find the time in hours, $\dfrac{t}{4}+\dfrac{t}{7}=1$ and the time will be 2.5 hours. So the correct answer is option A.

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Layna can paint a 350-square-foot room in 4 hours.It takes Bebe 7 hours to paint the same room.

Let t be the total time taken by both to paint.They are completing 1 job so the equation will be :

$\dfrac{t}{4}+\dfrac{t}{7}=1$

Further solving it we get;

7 t + 4 t = 28

11t = 28

t = 2.5 hours.

Therefore the equation can be used to find the time in hours, $\dfrac{t}{4}+\dfrac{t}{7}=1$ and the time will be 2.5 hours. So the correct answer is option A.

Given tan θ = 3/4 for acute angle θ, find the value of a and b for the statement cos θ = a/b.

Furkat [3]

Step-by-step explanation:

$\tan \theta = \frac{3}{4} \\ \\ \sec \theta = \sqrt{1 + { \tan }^{2} \theta} \\ \hspace{22 pt} = \sqrt{1 + {( \frac{3}{4} )}^{2} } \\ \hspace{22 pt} = \sqrt{1 + {\frac{9}{16} }} \\ \hspace{22 pt} = \sqrt{ {\frac{16 + 9}{16} }} \\ \hspace{22 pt} = \sqrt{ {\frac{25}{16} }} \\ \red{ \boxed{\bold{ \therefore \sec \theta = { {\frac{5}{4} }} }}} \\ \\ \cos \theta = \frac{1}{\sec \theta } = \frac{4}{5} = \frac{a}{b} \\ \\ \implies \: a = 4 \: and \: b = 5$
