$\sf \: 2x + 31 = 5$

$\sf \longmapsto \: 2x = 5 - 31$

$\sf \longmapsto \: 2x = -26$

$\sf \longmapsto{x }= \frac{ - 26}{2}$

$\sf \longmapsto \: x = - 13$

$\boxed{\sf - 13}$

2x + 31 = 5

2x = 5 - 31

2x = -26

x = -26/2

x = -13.

On a bicycle trail, the city is painting arrows like the one shown below: Upper pointing arrow with height of 15 and length of 1

Luden [163]

Answer:

229.5 $cm^{2}$

Step-by-step explanation:

In order to calculate the area of the arrow we need to calculate the area of the body of the arrow, and then the head of the arrow. The body of the arrow is a rectangle meaning that the area (Ar) can be calculated by multiplying the length by the height like so...

Ar = l * h

Ar = 11cm * 12cm

Ar = 132 $cm^{2}$

Now we need to find the area of the head of the arrow, which is a triangle and therefore we can use the formula for the area of a triangle (At) which is height times base divided by 2...

At = $\frac{h * b}{2}$

At = $\frac{15cm * 13cm}{2}$

At = $\frac{195cm^{2} }{2}$

At = 97.5 $cm^{2}$

Now we simply add both areas together to calculate the total area of the arrow...

132 $cm^{2}$ + 97.5 $cm^{2}$ = 229.5 $cm^{2}$

A machine is designed to fill toothpaste tubes, on an average, with 5.8 ounces of toothpaste. The manufacturer does not want any

pochemuha

The correct hypothesis that can be set up for this test is given as

H0: mu = 5.8

Ha: mu ≠ 5.8

<h3>What is a statistical hypothesis?</h3>

This is the method of inference that is made in a statistical testing in order to know if the dat available is able to support the claims that have been made.

What the manufacturer wants to know is the average filling of the machine. If it is within 5.8 or not.
