Answer:

0.5

Step-by-step explanation:

Given that height of 7 year old children are normally distributed with mean =49 inches and std deviation = 2inches

Brenda is 50 inches tall

This means her X score is 50

To convert this X score to Z score we use the formula given below

z=\frac{x-\mu}{\sigma}

Here we know all the values of x, mu and sigma

Just substitute

Z score

=\frac{50-49}{2} =\frac{1}{2} \\=0.5

Thus Z score of Brenda is 0.5

Help, i've been trying for around 30mins and I can't figure it out.
omeli [17]

Answer:

<h2><em><u>Option</u></em><em><u> </u></em><em><u>A</u></em><em><u> </u></em><em><u>and</u></em><em><u> </u></em><em><u>C</u></em></h2>

Step-by-step explanation:

As,

2 \sqrt{75}  + 3 \sqrt{50}

= 2 \sqrt{25 \times 3}  + 3 \sqrt{25 \times 2} (A)

= 2 \times 5 \sqrt{3}  + 3 \times 5 \sqrt{2}

= 10 \sqrt{3}  + 15 \sqrt{2} (C)

Can someone help me out ? Don't just guess the answer :(
Monica [59]
1) 2m+6 / m² + 7m - 12  +  (m+2)/(m+4)

= 2(m+3) / (m+4)(m+3)  + (m+2)/(m+4)

= 2/(m+4) + (m+2)/(m+4)

= 2+m+2 / (m+4)

= m+4 / m+4

= 1  [ Option A ]

Answer 2) 3/ (x+4)  + 7/ (x-3)

=  3(x-3) + 7(x+4)/ (x² +x - 12)

= 3x-9 + 7x + 28 / (x² +x - 12)

= 10x + 19 / (x² +x - 12)  [ Option A ]

Hope this helps!

The area of a rectangle in 24 units. A diagonal drawn from one corner to another divides the rectangle into two right triangles.
nlexa [21]

Answer:

12 sq u

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, assuming the shaded triangle is one of those two triangles, its area would be 12 sq u.

Why? Because its length would be the same as the retances, as would its height, and to find the area of a triangle, you'd do L*H/2 which would be 24/2=12 sq u

(っ◔◡◔)っ ♥ Hope this helped, have a great day! ♥
