-5a – 2 >8 equals a<−2

2a +4>14 equals a>5

Answer:

x = 1.

Step-by-step explanation:

√25x + 10 = 15

√25x = 15 - 10

√25x = 5

squaring both sides:

(√25x)^2 = (5)^2

25x = 25

hence x = 1.

The required equation of the line is 6x + y  = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

First, we have to determine the slope of the line 6x + y = 6 by placing it into a slope-intercept form:

6x + y = 6 ⇒ y = -6x + 6

Therefore, the slope of the line is m = - 6

Since the required line passes through the point at (2, -5).

Let the line  (y - y₁) = m(x -x₁  )

Here x₁ = 2, y₁ = -5

Substitute the values in the equation,

So, y - (-5) = -6(x - 2)

⇒ y  + 5 = -6x + 12

⇒ 6x + y  = 7

Hence, the required equation of the line is 6x + y  = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).

Answer:

144 miles

Step-by-step explanation.

If the bus has a consumption speed of 18 miles to a gallon, multiply 8 times 18 for the length of the trip!

Answer:

144 miles

Step-by-step explanation:

Distance = (fuel economy measure)(number of gallons of gas used)

Here,

Distance = (18 mpg)(8 gallons) = 144 miles

Answer:

X = 40

Step-by-step explanation:

{ 2 (x + 10)} = (3x - 30)

2x + 10 = 3x - 30

10 = 3x - 2x - 30

10 + 30 = 1x

40 = 1x

X = 40

Complete Question

Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph, use their z-scores to find which dog is running faster relative to its breed

Answer:

Miniature dachshunds is faster

Step-by-step explanation:

From the question we are told that

   The speed of the Miniature dachshunds is  [tex]x = 14.8 \ mph[/tex]

    The mean for the Miniature dachshunds is [tex]\mu_1 = 13 \ mph[/tex]

    The standard deviation for the Miniature dachshunds is  [tex]\sigma_1 = 1.6 \ mp h[/tex]

    The speed of the Labrador is [tex]y = 25 \ mph[/tex]

     The mean for the Labrador is [tex]\mu_2 = 22 \ mph[/tex]  

    The standard deviation for the Labrador  is  [tex]\sigma_2 = 2.8 \ mp h[/tex]

Generally the z-score for the Miniature dachshunds is

     [tex]z_1 = \frac{x- \mu_1 }{\sigma_1}[/tex]

=>  [tex]z_1 = \frac{14.8 - 13 }{1.6}[/tex]

=>  [tex]z_1 = 1.125[/tex]

Generally the z-score for the Labrador is

     [tex]z_2 = \frac{x- \mu_2 }{\sigma_2}[/tex]

=>  [tex]z_2 = \frac{25 - 22 }{2.8}[/tex]

=>  [tex]z_2 = 1.071[/tex]

From the value obtained we see that  [tex]z_1 > z_2[/tex] , hence miniature dachshund  is  faster

Answer:

9 ft

Step-by-step explanation:

The ladder is 15 feet long

The wall is 12 feet high

Therefore the distance between the base of the wall and the ladder can be calculated by applying phythagoreans theory

c^2= a^2 + b^2

15^2 = a^2 + 12^2

225= a^2 + 144

225-144= a^2

a^2= 81

a= 9 ft

Answer:

120

Step-by-step explanation:

I’m assuming you ment 12(2+7+1)

soooo

2+7=9

9+1=10

so here’s it is now

12(10)

when there’s 2 numbers like that you multiply

so 12 x 10 = 120

and there’s your answer

Step-by-step explanation:

The above statement is not correct since the time and cost of the study is of no concern to the one who is conducting the study, The person conducting the study having ample time and resource, means that it  would be better for the person to expand the scope of the study by conducting it over the whole population because that will give a more accurate result rather than conducting the study over a few samples .

Answer:

the answer is 5

Step-by-step explanation:

it is 5 because 2+8-3=5

Answer:

We set up 2 equations:

n - m = 80 so "n" is the larger number

A) n - m = 80

B) m / n = .6

A) n = 80 + m

B) m = .6 n   so B) n = (5/3) m

We substitute B) into A)

(5/3) m = 80 + m

(2/3) m = 80

m = 1.5 * 80

m = 120

n = 200
