Three Times A Number X Is The Same As Doing:
3X.
However, If It Said:
Three Times A Number Plus X, It Would Be Something Like:

Why do I think I'm ugly

Tanya [424]

Answer:

Ok listen here

Step-by-step explanation:

You are like the earth.

On the inside is a bright center and lava. When lava comes to the surface as a volcano, many people think it's ugly and dangerous, but other people think that it's beautiful.

We all know that a lot of people think the surface of the earth is ugly, and they have given up hope that people can change it, but the truth is that, the world is beautiful and we can change it.

You are beautiful and the people on your earth are represented as your brain. Your brain needs to tell you to look at yourself and to say that you are beautiful. You can change your mindset to tell you that you don't care what other people say, all that matters is what you say.

Always remember that :)

Answer:the smallest possible sum of the two numbers is 537

Step-by-step explanation:

Two three-digit numbers are made up of six different digits.

To interpret this, let the two three digit numbers be;

ABC and. DEF

The first digit of the second number is twice as big as the last digit of the first number.

Interpret;

D=2C

The first digit of the first number can be 1, the second digit 0 and the third digit 2.

102.

For the second number:

D=2C

The first digit is 4, second digit 3 and last digit 5 since no repetition of digits

435.

Answer:the smallest possible sum of the two numbers is

102+435= 537

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

X : 18.0, 30.7, 19.8, 27.1, 22.3, 18.8, 31.8, 23.4, 21.2, 27.9, 31.9, 27.1, 25.0, 24.7, 26.9, 21.8, 29.2, 34.8, 26.7,31.6

True standard deviation (σ) = 4

α = 0.01

Mean (m) of the data:

Σ(X) /n = 520.7/20

m = 26.035 = 26.04

Uaing calculator :

Sample standard deviation (s) = 4.785

Null hypothesis : μ = 25

Alternative hypothesis : μ > 25

Test statistic (t) : (m - μ) / (s/√n)

t = (26.04 - 25) / (4.785/√20)

t = 0.972

We can obtain the p value using the pvalue from t score calculator :

df = n - 1 = 20 - 1 = 19

Decision:

If p < 0.01 ; reject null

p(0.972, 19) = 0.1716

Since p > 0.1716 ; we fail to reject the Null
