Answer:

Solution given:

[tex] {x}^{2} - 13x + 12 = 0[/tex]

doing middle term factorization

x²-12x-x+12=

x(x-12)-1(x-12)=0

(x-12)(x-1)=0

either

x=12

or

x=1

value of x is 1 or 12.

Answer:

x = 65

y = 71

z = 44

Step-by-step explanation:

y = 71 because If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 2) ← 2 points on the line

m = [tex]\frac{2-0}{1-0}[/tex] = [tex]\frac{2}{1}[/tex] = 2

Answer:

A=152.32 cm^2

Step-by-step explanation:

A=2(wl+hl+hw)

A=2(6.8*3.4+5.2*3.4+5.2*6.8)

A=2(23.12+17.68+35.36)

A=2(76.16)

A=152.32

Answer:

The first where z = -1.78 and p-value = 0.0375 would be the correct answer

Hope it helps

Using the z-distribution, it is found that the test statistic and the p-value of the test are given as follows:

z = –1.78, P-value = 0.0375.

At the null hypothesis, it is tested if the proportion is of 85%, that is:

[tex]H_0: p = 0.85[/tex]

At the alternative hypothesis, it is tested if it is less than that, hence:

[tex]H_1: p < 0.85[/tex].

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

In this problem, we have that the parameters are given as follows:

[tex]n = 50, \overline{p} = 0.76, p = 0.85[/tex]

Hence, the test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.76 - 0.85}{\sqrt{\frac{0.85(0.15)}{50}}}[/tex]

z = -1.78.

Using a z-distribution calculator, considering that we have a left-tailed test, as we are testing if the proportion is less than a value, the p-value is of 0.0375.

Answer:

1440 it is right because

Step-by-step explanation:

Decagon is a 10-sided polygon.

Formula to find the sum of interior angles of a n-sided polygon is  

=  (n - 2) ⋅ 180°

By using the formula,  sum of the interior angles of the given decagon (10-sided polygon) is  

=  (10 - 2) ⋅ 180°

=  8 ⋅ 180°

=  1440°

Step-by-step explanation:

2miles

The required shortest between the two houses is given as 10 miles. Option B is correct.

In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.

Here,
Matthew lives 6 miles east of the school drew lives 8 miles north of the school.

Let's assume, the position of Mathew and drew house create the right angle with the school,
hypotenuse distance between Mather and Drew's house be x,
Applying the Pythagoras theorem,

x = √[8² + 6²]
x = √[100]
x = 10 miles

Thus, the required shortest between the two houses is given as 10 miles. Option B is correct.
