Yanka [14]3 years ago
5 0

Step-by-step explanation:

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

  • 1. slope= 1/4,y intercept = 4
  • 2. y-5=-4(x+1)

And we need to find the slope intercept form of the line . The slope intercept form of a line is y = mx + c , where m is the slope and c is the y intercept. Substitute respective values ,

<u>Solution</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u><u> </u>

:\implies y = mx + c

:\implies y = 1/4 x + 4

:\implies 4y = x + 16

:\implies x - 4y + 16 = 0

<u>Solution</u><u> </u><u>2</u><u> </u><u>:</u><u>-</u><u> </u>

:\implies y - 5 = -4( x +1)

:\implies y -5 = -4x -4

:\implies y = -4x +1

Answer:

\large{ \tt{❃ \: EXPLANATION}} :

  • We're provided the figure of trapezium in which 2 m and 7m are the opposite parallel sides and 10m is the height.

  • The formula to found out the area of a trapezium is \frac{1}{2}  \tt{h(a + b)} where h is the height and a & b are the opposite parallel sides .

\large{ \tt{❁ \: LET'S \: START}} :

\boxed{ \large{ \tt{❊ \: AREA \: OF \: TRAPEZIUM \: (A) =  \frac{1}{2} h(a + b)}}}

- Plug the values & then simplify!

\large{ \tt{↬ \frac{1}{2}  \times 10(2 + 7)}}

\large{ \tt{↬ \frac{1}{2} \times 10 \times 9 }}

↬ \boxed{ \large{ \tt{45 \:  {m}^{2} }}}

  • Hence , The required answer is <u>45</u> square meters .

t the Fidelity Credit Union, a mean of 5.8 customers arrive hourly at the drive-through window. What is the probability that, in
zhuklara [117]

Answer:

0.5217

Step-by-step explanation:

Given that:

mean \mu = 5.8

Using Poisson Probability formula:

P(X=x) = \frac{   (e^{- \mu} * {\mu^x) }}{x!}

P(X>5.8)=1-P(X \leq5)

= 1-[P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)]

= 1 -[\frac{(e^{-5.8}*5.8^0)    }{ 0!   } + \frac{(e^{-5.8}*5.8^1)    }{ 1!   } +\frac{(e^{-5.8}*5.8^2)    }{ 2!   } +\frac{(e^{-5.8}*5.8^3)    }{ 3!   } +\frac{(e^{-5.8}*5.8^4)    }{ 4!   } +\frac{(e^{-5.8}*5.8^5)    }{ 5!   } ]

=1-(0.003+0.0176+0.0509+0.0985+0.1428+0.1656)

=1-0.4783

=0.5217

∴ the probability that, in any hour, more than 5 customers will arrive =0.5217

Please help!Your fixed expenses are $1,151.65/month. You saved 4 months' worth in an emergency fund, investing 25% in a savings
FinnZ [79.3K]
4 x 1,151.65 = 4,606.60 
<span>This is invested in two accounts. Twenty-five percent is invested in savings (4,606.60 x 25% = 1,151.65). The remainder is invested in a CD (4,606.60 - 1,151.65 = 3,454.95) </span>

<span>Interest accrued for savings. *Note: The interest rates given are for a full year, but you want to calculate interest for only 60 days. </span>
<span>1,151.65 x 0.033 x 60/360 = $6.33 </span>
<span>Interest accrued for CD </span>
<span>3,454,95 x 0.043 x 60/360 = $24.76 </span>
<span>Total interest accrued </span>
<span>6.33 + 24.76 = $31.09 </span>

<span>Note: 0.033 and 0.043 = 3.3% and 4.3%. Also, the 360 day year is normally used when doing these types of problems.</span>

I buy a MP3 player for £40 in a sale where it was 20% off. What was the original price
natta225 [31]
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
