Answer: The data set is missing therefore I will give you a more general answer

answer : The mean value will shift ( to the right ) by 20

Step-by-step explanation:

when a number is added to each data value in a data set the mean value will shift ( to the right ) likewise the mode, and Median by the same amount that was added to the data set . but the range and IQR will remain unchanged

If you flip the five coins, and the probability of one coin being "tails" is 0.50, what is the probability of getting "tails" on

jenyasd209 [6]

Answer: 0.03125

Step-by-step explanation:

We know that the probability of getting a tail , we toss a fair coin = 0.5

Given : Total number of trials = 5

Using binomial probability formula :

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trails, n is total number of trials and p is the probability of getting success in each trial.

The probability of getting "tails" on all five coins :_

$P(x=5)=^5C_5(0.5)^5(1-0.5)^0=(1)(0.5)^5=0.03125$

Hence, the probability of getting "tails" on all five coins =0.03125

Rom4ik [11]

Step-by-step explanation:

Easy:)

$7)4a^{8}b^{12} \\8)25x^{6}y^{8}\\9)x^{9}y^{9}$ × $xy^{2}$

= $x^{10}y^{11}$

$10)a^{3}$ × $a^{8}b^{4}$

= $a^{11}b^{4}$

$11)4a^{2}b^{4}$ × $9a^{4}b^{2}$

$=36a^{6}b^{6}$

Have a nice day! :)
