Answer:

N = 17

Step-by-step explanation:

In a parallelogram the opposite angles are congruent, hence

4n - 2 = 2n + 32 ( subtract 2n from both sides )

2n - 2 = 32 ( add 2 to both sides )

2n = 34 ( divide both sides by 2 )

n = 17

An engineering crew ran several tests on a new automobile engine they were designing. The mean fuel consumption was 52.4 miles p

zhenek [66]

Any value which is more than 2 standard deviations away from the mean is considered to be "unusual."

2 standard deviations above the mean 52.4 mp would be 52.4+2(1.8), or 56; 2 std devs below the mean would be 52.4 - 2(1.8), or 48.8. Thus, any value larger than 56 or any value smaller than 48.8 would be "unusual."

54.8, 49.1 and 51.3 are not unusual; 56.5 is unusual, because it's greaster than 56.

They're just hired a new employee to work in your bike shop in one hour the employee burns 55 chocolate chip cookies if this rep

KATRIN_1 [288]

Answer:

250 cookies

Step-by-step explanation:

The employee burns 55 chocolate chip cookies

if this represented 22% of the days production

Let x = the total production of cookies for the day

how many cookies did you plan on producing that day?

22% of x = 55

22 / 100 * x = 55

0.22x = 55

Divide both sides by 0.22

x = 55 / 0.22

= 250

x = 250 cookies

Therefore, the total production of cookies for the day is 250

U = 6i – 10j<br> g= -81 – 11j<br> Find: -3u + 5g

VARVARA [1.3K]

Answer:

$-3u + 5g =-58i -25j$

Step-by-step explanation:

Given

$u = 6i - 10j$

$g=-8i - 11j$

Required

$-3u + 5g$

We have:

$-3u + 5g$

This gives:

$-3u + 5g = -3(6i - 10j) + 5(-8i - 11j)$

Open bracket

$-3u + 5g = -18i + 30j - 40i - 55j$

Collect like terms

$-3u + 5g = -18i - 40i+ 30j - 55j$

$-3u + 5g =-58i -25j$

<h2><u>Given:</u><u>-</u></h2>

Points C = (-7,2) → $\sf{(X_1,Y_1)}$
D = (3,12) → $\sf{(X_2,Y_2)}$

The Midpoint of CD.

<h2><u>Required</u><u> </u><u>Response</u><u>:</u><u>-</u></h2>

Let,

Midpoint of CD be (x,y).

WKT,

$\boxed{\sf{(x,y) = \frac{X_1+X_2}{2},\frac{Y_1+Y_2}{2}}}$

$→\;{\sf{\frac{-7+3}{2},\frac{2+12}{2}}}$

$→\;{\sf{\frac{-4}{2},\frac{14}{2}}}$

$→\;{\sf{-2,7}}$

The Midpoint of CD ◕➜ $\Large{\red{\mathfrak{(-2,7)}}}$

Let,

The centre be O

Radius = CO & OD

Here, C = (-7,2) → $\sf{(X_1,Y_1)}$

O = (-2,7) → $\sf{(X_2,Y_2)}$

$\boxed{\sf{Distance = \sqrt{(X_2-X_1)²+(Y_2-Y_1)²}}}$

$→\;{\sf{\sqrt{(-2+7)²+(7-2)²}}}$

$→\;{\sf{\sqrt{5²+5²}}}$

$→\;{\sf{\sqrt{25+25}}}$

$→\;{\sf{\sqrt{50}}}$

$→\;{\sf{5√2 (or) 7.07}}$

Radius of Circle ◕➜ $\Large{\red{\mathfrak{7.07}}}$
