Using specific data, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eat

pshichka [43]

Answer:

Test statistic:

z = (0.67 - 0.63) / 0.033 = 1.21

p - Value = P(z > 1.21) = 0.106

My conclusion: Fail to reject null hypothesis

No, there is no evidence of a difference

Find the area of a compound shape Can you please explain

gtnhenbr [62]

Answer:

$A=292.53~m^2$

Step-by-step explanation:

Area of a Compound Shape

The shape shown in the image is made of two shapes: Half a circle of radius 8 m and a triangle of base 24 m and height 16 m.

The area of a circle of radius r is:

$A_c = \pi r^2$

The area of a triangle of base b and height h is:

$\displaystyle A_t=\frac{b.h}{2}$

Calculate the area of the circle:

$A_c = \pi 8^2$

$A_c = 64\pi$

Area of half the circle:

$A_c/2 = 32\pi~m^2$

Area of the triangle:

$\displaystyle A_t=\frac{24\cdot 16}{2}$

$A_t=192~m^2$

The area of the shaded shape is:

$A=32\pi~m^2+192~m^2$

Substituting the value of pi:

$\mathbf{A=292.53~m^2}$

Please answer this question! Easy, just not for me! Will give brainliest. :)

Answer:

20.3 cm. to the nearest tenth.

Step-by-step explanation:

Using the Pythagoras Theorem:

CR^2 = CS^2 + SR^2

= 6^2 + 13^2

= 205

CR = √205 cm.

UR = CR (because they are both radii of the circle).

So UR = √205

and SU =6 + √205

= 20.3 cm to the nearest tenth.
