Answer: 24 cm^2

explanation: the area of the triangle would be 6 because (3*4)/2=6. the area of the larger rectangle would be 12 because 4*3=12. the missing side is found by subtracting 8 by 4. the smaller rectangle’s area would be 6 because 4*1.5=6. add 6, 12, and 6 together and you get 24. i hope this helps!!

babunello [35]

Answer: 0.345

Step-by-step explanation:

Given: The the setup for this hypothesis test:

H_0:p=0.65\\\\H_a:p

Since , the alternative hypothesis is left tail , so the test is left tail test.

P_0=0.65\\\\Q_0=1-0.65=0.35\\\\p=\dfrac{126}{200}=0.63

The test static for population proportion is given by :-

z=\dfrac{p-P_0}{\sqrt{\dfrac{P_0Q_0}{n}}}\\\\\Rightarrow\ z=\dfrac{0.63-0.65}{\sqrt{\dfrac{0.65-0.35}{126}}}=−0.409878030638\approx-0.4

The p-value of z = P(z

PLSSS HELPPPP!!!!!! ITS DUEEE TODAYYYY !!! FIND THE VALUE OF X.
LekaFEV [45]

\huge\bold{To\:find :}

The value of x°.

\large\mathfrak{{\pmb{\underline{\orange{Solution}}{\orange{:}}}}}

The value of x° is 150°. ✅

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}

We know that,

\sf\purple{Sum\:of\:angles\:on\:a\:straight\:line\:= \:180°}

➡ 81° + y° = 180°

➡ y° = 180° -81°

➡ y° = 99°

Since an exterior angle of a triangle is equal to the sum of the two opposite interior angles, we have

x° = y° + 51°

Substituting the value of ''y°" in the above equation,

➪ x° = 99° + 51°

➪ x° = 150°

\sf\red{Therefore, \:the\: value \:of \:x°\: is \:150°.}

<u>Note</u>:-

Kindly refer to the attached file.

There are 6 possibilities, and so each arrangement has a 1 over 6 chance of being used.
