Answer:

Length , time, mass, current, temperature, amount of mass, luminous intesity

m, sec, kg, A, K, mol, cd

Step-by-step explanation:

Seven basic SI units are used for measurement of

Meter for length

Second for time

Kilogram for mass

Ampere for current

Kelvin for temperature

Mole for amount of mass

Candela for luminous intensity

Symbols of these SI units are

m for meter

sec for second

kg for kilogram

A for ampere

K for kelvin

mol for mole

cd for candela

A(-2, 2), B(4, 2), C(-6, -1), D(0, -1)

AB = CD = 4 - (-2) = 4 + 2 = 6

BD = AC. Use the formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates of the points B and D:

$d=\sqrt{(-1-2)62+(0-4)^2}=\sqrt{(-3)^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

BD = AC = 5

The perimeter of parallelogram ABCD:

P = 2 · 6 + 2 · 5 = 12 + 10 = 22

<h3>Answer: a. 22 units.</h3>

Solve for x. -3(3x+3)= -2x+5

notsponge [240]

Answer:

x = -2

Step-by-step explanation:

So we are given the equation -3(3x + 3) = -2x + 5 and we are solving for x. We will have to try to get the equation into the form x = _. That would be our answer.

-3(3x + 3) = -2x + 5

Distribute the -3 on the left side.

-9x - 9 = -2x + 5

Add 2x to both sides to get rid of the -2x on the right side.

-9x - 9 + 2x = 5

Simplify.

-7x - 9 = 5

Add 9 to both sides to get rid of the - 9 on the left side.

-7x = 5 + 9

Simplify.

-7x = 14

Divide both sides by -7 to get rid of the coefficient of -7 on the left side.

x = 14 ÷ (-7)

Simplify.

x = -2

The answer is x = -2.

I hope you find my answer helpful. :)

Put a lid on it! The supplier is considering two changes to reduce to 1% the

bija089 [108]

Answer:

A) 3.996 inches

B) 0.01

C) option B

Step-by-step explanation:

Note: The diameter of the lid is between : 3.95 and 4.05

A) calculate the supplier set mean diameter

std = 0.02 inch

P( x < 3.95 ) = 1% = 0.01

= P ( Z < $(\frac{3.95 - u }{0.02})$ ) = P ( Z < -2.3263 ) = 0.01

therefore :

$(\frac{3.95 - u }{0.02})$ = -2.3263

hence :<em> u </em>= 3.996 inches ( mean diameter )

B) At mean diameter = 3.98 calculate the value of std

P ( X < 3.95 ) = 0.01

= P ( Z < $( \frac{3.95-3.98 }{std } )$ ) = P ( Z < -2.3263 ) = 0.01

therefore

$( \frac{3.95-3.98 }{std } )$ = -2.3263

hence std = 0.01 inch

C) option B is preferable because its mean diameter is smaller and the percent of lids too large to fit is considered more carefully using option B
