Answer:

$\frac{1}{ \sqrt[7]{ {12}^{4} } }$

Step-by-step explanation:

${12}^{ - \frac{4}{7} } is \: the \: same \: as \\ \frac{1}{ {12}^{ \frac{4}{7} } } \\ {12}^{ \frac{4}{7} } can \: also \: be \: expressed \: as \\ \sqrt[7]{ {12}^{4} }$

Therefore:

${12} ^ { -\frac{4}{7} } \: is \: equivalent \: to \\ \frac{1}{ \sqrt[7]{ {12}^{4} } }$

Justin and his children went into a grocery store and he bought $18 worth of bananas and mangos. Each banana costs $0.60 and eac

Igoryamba

Answer:

x=10 and y= 8.

Step-by-step explanation:

Given that the cost of 1 banana = $0.60

Cost of 1 mango = $1.50.

Total cost= $ 18

Here, x be the number of bananas and y be the numbers of mangos,

As the number of bananas is 2 more than the number of mangos,

So, x=y+2

$\Rightarrow y=x-2 \cdots(i)$

Cost of x bananas $=\$ 0.60 \times x$

Cost of y mangos $=\$ 1.50 \times y$

Total cost = 0.6x+1.5y

$\Rightarrow 18 = 0.6x+1.5y\\\\\Rightarrow 1.5y=18-0.6x\\\\\Rightarrow y= 12 - 0.4 x \cdots(ii).$

Solving both the equations (i) as well as (ii), graphically as shown in the figure by plotting both the graphs.

Both the graphs intersect at the point (10,8) as shown in the graph.

So, the solution of both the equations is, (x,y)=(10,8). i.e

The number of bananas = x= 10 and

the number of mangos = y = 8.

Here is the histogram of a data distribution. What is the shape of this distribution?

inna [77]

Answer:

This histogram is unimodal skewed. There are two parts to this answer. The first part has to do with the number of modes. This would be the item that is occurring the most frequently. In this case the mode is only 4. It is occurring more than any other.

The second part of this has to do with the distribution of the data as it is displayed on the histogram. There are 4 pieces of data that are only occurimg one time on the right of the histogram. We call this skewing the data. When both sides looks almost the same we say it is symmetric.

This is the last one lol . find the value of x

netineya [11]

Answer:

Step-by-step explanation:

Since these 115 and the angle adjacent to x are alternate interior angles, then that angle is equal to 115. That angle and x add up to 180, so we do 180-115, which is equal to 65.
