All angles in a triangle add up to 180 so 180 - 60 = 120 then 180 - 155 = 25 then 25+65 = 90 that is the remaining angle but finally 180 - 90 = 90 is the missing angle

What is a equivalent fraction for 24/30
liq [111]
There's an infinite number of equivalent fractions for 24/30 - all you need to do is to divide or multiple both numerator and denominator by the same number. For example:

24/30 = 48/60 (because 24 * 2 = 48 and 30 * 2 = 60)
24/30 = 12/15 (because 24 ÷ 2 = 12 and 30 ÷ 2 = 15)
24/30 = 72/90 (because 24 * 3 = 72 and 30 * 3 = 90)
24/30 = 4/5 (because 24 ÷ 6 = 4 and 30 ÷ 6 = 5)
etc...

Answer:

=−36p+52x+1324

Step-by-step explanation:

7x−7+35−34p+45x−2p+64

=7x+−7+35+−34p+45x+−2p+1296

Combine Like Terms:

=7x+−7+35+−34p+45x+−2p+1296

=(−34p+−2p)+(7x+45x)+(−7+35+1296)

=−36p+52x+1324

xP(x)00.2510.0520.1530.55Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal pl
Nookie1986 [14]

The Solution:

Given:

Required:

Find the standard deviation of the probability distribution.

Step 1:

Find the expected value of the probability distribution.

E(x)=\mu=\sum_{i\mathop{=}0}^3x_iP_(x_i)\begin{gathered} \mu=(0\times0.25)+(1\times0.05)+(2\times0.15)+(3\times0.55) \\  \\ \mu=0+0.05+0.30+1.65=2.0 \end{gathered}

Step 2:

Find the standard deviation.

Standard\text{ Deviation}=\sqrt{\sum_{i\mathop{=}0}^3(x_i-\mu)^2P_(x_i)}=(0-2)^2(0.25)+(1-2)^2(0.05)+(2-2)^2(0.15)+(3-2)^2(0.55)=4(0.25)+1(0.05)+0(0.15)+1(0.55)=1+0.05+0+0.55=1.60

Thus, the standard deviation is 1.60

Answer:

1.60

Alchen [17]

Answer: There is 48.14% of dogs are male .

Step-by-step explanation:

since we have given that

Total number of dogs = 37

Number of dogs that are female = 24

Number of dogs that are male  is given by

37-24\\\\=13

We need to find the percentage of dogs are male:

So, Percentage of the dogs are male is given by

\frac{13}{27}\times 100\\\\=48.14\%

Hence, there is 48.14% of dogs are male .
