Inequality task : -3(x+2)>-69-12x

Mathematics
1 answer:
lys-0071 [83]3 years ago
7 0

Answer:

-7 > x

Step-by-step explanation:

first we expand the brackets so it will be -3x -6>-69-12x

then we can convert the > to = so it will be :

-3x -6=-69-12x

we can now try to solve the equation for x so :

-3x -6= -69-12x

-6 = -69-9x

63 =-9x

7 = -x

-7 = x

we can then change the symbols back so it will be:

-7 > x

masya89 [10]

Answer:

The correct option is option c.

H0: p not equal to 0.5

H1: p equal to 0.5

Step-by-step explanation:

1. H0: p not equal to 0.5

H1: p equal to 0.5

2. P cap = 104/ 260

P cap = 0.4. ( where p cap is the sample proportion)

3. Find the test statistic

Using : Z = ( p cap - p) /√ [(p ×q)/n] where p = 0.5 q= 1-p = 0.5. n=260

Z = -3.23

4. P value = 0.006

5. Since p value is less than the alpha level (0.01) . we reject the null hypothesis and conclude that the touch therapists are not effective.

The top of a desk is shaped like a trapezoid. The bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk
Stolb23 [73]

Answer:

28 centimeters.

Step-by-step explanation:    

Let w be width of desk.

We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.

Since the area of trapezoid is half the sum of parallel sides times its height.

\text{Area of trapezoid}=\frac{h}{2}*(a+b), where

h= Height of trapezoid,

a and b= Length of parallel sides of trapezoid.

We have been given that the height of the trapezoid is the width of the desk.

Upon substituting our given vales in above formula we will get,

791=\frac{w}{2}*(26.5+30)

791=\frac{w}{2}*(56.5)

791=w*28.25

w=\frac{791}{28.25}

w=28

Therefore, the width of trapezoid is 28 centimeters.
