What is the slope of a line perpendicular to the line y = −14x – 1?
mash [69]

Answer:

<h2>         m = ¹/₁₄</h2>

Step-by-step explanation:

y=m₁x+b₁   ⊥   y=m₂x+b₂   ⇔    m₁×m₂ = -1

{Two lines are perpendicular if the product of theirs slopes is equal -1}

y = -14x - 1   ⇒   m₁ = -14

-14×m₂ = -1        ⇒    m₂ = ¹/₁₄

So, the slope of a line perpendicular to the line y = -14x - 1 is m = ¹/₁₄

Fidn the points of intersection
Sedbober [7]

EQ. 1: x + y = 8

EQ. 2: 4x-y = 7

Rewrite EQ. 1 as EQ. 3: x = 8-y

Replace x in EQ.2 with EQ. 3:

4(8-y) - y = 7

Use the distributive property:

32 - 4y - y = 7

Combine like terms:

32 - 5y = 7

Subtract 32 from each side:

-5y = -25

Divide both sides by -5

y = -25 / -5

y = 5


Now replace y with 5 in EQ. 3 to solve for X:


x = 8-5

x = 3


The point of intersection is X = 3, Y = 5, which is written as (3,5)

How do I solve this STATS question?
k0ka [10]
We have the following data:

Margin of Error = E = 2.7 % = 0.027
Sample size = n = 900
Proportion of adults in favor = p = 60% = 0.6

We need to find the confidence level. For this first we need to find the z value.

The margin of error for a population proportion is given as:

E=z* \sqrt{ \frac{p(1-p)}{n} }

Using the values, we get:

0.027=z* \sqrt{ \frac{0.6*0.4}{900} } \\  \\ &#10;0.027=z*0.016 \\  \\ &#10;z= \frac{0.027}{0.01633}  \\  \\ &#10;z=1.65

As, seen from the z table, z=1.65 corresponds to the confidence level 90%. So, the answer to this question is option B

An object is moving at a speed of 850 miles per hour. Express this speed in meters per minute.
MAVERICK [17]

Answer:

it would be 1385

Step-by-step explanation: because 850 miles per hour converted into meter per min would be 22799.04 meters per sec and then u would Find the number in the whole number place 4 and look one place to the right for the rounding digit on the right side of the decimal point 7. Round up if this number is greater than or equal to 5 and round down if it is less than 5

So the answer is 1385
