Answer:

18: x=98 y=38

19: x=20 y=50

Step-by-step explanation:

To figure out figure 18 you would first figure out x and a triangle equals 180 so 180- (36+46) which is 180-82= 98 and then there are vertical angles between the right and left side so x is equal to one of the angles on the right so 98+44= 142 and 180-142= 38

Then to figure out figure 19 you would first find y by adding 39 and 91 to get 130 and 180-130=50 and then 180-91 (for the angle in the bottom right for the left triangle) is 89 so 89+71=160 and 180-160 is 20.

Answer:

figure1.

x=98

y=38

fig2.

x=20

y=50

Step-by-step explanation:

fig 1

46+36+x=180(sum of all side)

x=98

the opposite angle of x Is also 98 being (V.O.A)

98+44+y=180

y=38

fig2

x+71=91(sum of 2 opposite interior angle is equals the exterior angle)

x=20

39+91+y=180(sum of angles of triangle)

y=50

Suppose that in a random selection of 100 colored​ candies, 26​% of them are blue. The candy company claims that the percentage
quester [9]

Answer:  a) -0.2252, b) 0.8219

Step-by-step explanation:

Since we have given that

Sample size n = 100

Probability that candies are blue = p= 0.26

Probability that company claims that it is blue candy = P = 0.27

So, Q = 1-P= 1-0.27 = 0.73

So, Null hypothesis : H_0:p=P

Alternate hypothesis : H_1:p\neq P

So, the test statistic would be

z=\dfrac{p-P}{\sqrt{\dfrac{P.Q}{n}}}\\\\z=\dfrac{0.26-0.27}{\sqrt{\dfrac{0.27\times 0.73}{100}}}\\\\z=-0.2252

Since α = 0.05

So, critical value of z = 1.96

p-value = P(Z>Z(calculated)

Using the excel function , we get that

P(z>0.2252)\\\\=2\times 0.410.911845\\\\=0.8219

Hence, a) -0.2252, b) 0.8219

The cosine law
romanna [79]
\bf \textit{Law of sines}
\\ \quad \\
\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\
-------------------------------\\\\

\bf \cfrac{sin(88^o)}{39.9}=\cfrac{sin(A)}{31}\implies \cfrac{31\cdot  sin(88^o)}{39.9}=sin(A)
\\\\\\
sin^{-1}\left[ \cfrac{31\cdot  sin(88^o)}{39.9} \right]=sin^{-1}\left[ sin(A) \right]
\\\\\\
sin^{-1}\left[ \cfrac{31\cdot  sin(88^o)}{39.9} \right]=\measuredangle A
\\\\\\
50.93841^o\approx \measuredangle A\qquad thus\qquad \measuredangle C\approx 41.0619^o
