The Range is going to be -10, -7, -4, -1, 2
Answer:
-5
Step-by-step explanation:
-5x-12= 13 add 12 to both sides
-5x-12 + 12= 13 + 12 ➡ -5x = 25 divide both sides by 5
-5x ÷ 5 = 25 ÷ 5 ➡ -x = 5 and x = -5
Answer:
4.8%
Step-by-step explanation:
21% of 18
following the BODMAS rule, OF means multiplication
and also this sign% always means 100
so,it will be 21/100 * 18/1
this a laptop so i cant put it in a fraction way.....okay
this is how it shows...21/100 * 18/1
lets divide....
21/100 * 18/1
we will use 2 to divide
2 in 100=50
2 in 18=9
so it will be 21/50 * 9/1
nothing can divide so we will multiply
21*9/50*1
189/50=3.78≈4.8%
Step-by-step explanation:
Sol
Given that ,
mean =300
standard deviation =a =70
n=100
ux=128
a ) within 6 =300 +/-6 : 294, 306
P(294' ' 306)
: P(-0.86 : Z ' 0.86)
: P(Z ' 0.86) - P(Z ' -0.86)
Using z table,
: 0.8051-0.1949
: 0.6102
Probability : 0.6102
a ) within 18 =300 18 : 294, 318
P(294' ' 306)
: P(Z ' 2.57) - P(Z ' -2.57)
Using z table,
:0.9949-0.0051
:0.9898
Probability =0.9898
The correct answer for the question that is being presented above is this one: "Correlation must be between 0 and 1; A correlation of r = .01 means there is no significant correlation; Correlation must be between -1 and 1; <span>Correlation is a numeric measure of the strength and the direction between two categorical variables."</span>
