Answer:

1 and 3 are irrational!!! The others are all rational

Step-by-step explanation:

1 and 3 are never terminating and they are not repeating, therefore, they are irrational! All the others are either terminal (they have a decimal that stops) or they are repeting and those repeting numbers can be written as a fraction, for example 0.2222... can be written as 2/9

How to factor 4x^2+7x-15
GuDViN [60]
4x^2+7x-15

Break the expression into group:

(4x^2+5x)+(12x-15)

factor out x from 4x² - 5x : x (4x-5)
factor out 3 from 12x-15 : 3 (4x-5)

=x(4x-5)+3(4x-5)

factor out common term (4x-5) :

= (4x-5)(x+3)

hope this helps!

To be considered for pilot school, 12 students took a spatial reasoning test that resulted in this list of scores. Find the valu
lord [1]

Answer:

the 90th percentile is 145

Step-by-step explanation:

Data provided:

152 121 130 143 122 101 137 98 138 127 145 117

Number of students considered, n = 12

To find:

90th percentile

Now,

Step 1 : Arrange the data in ascending order

98, 101, 117, 121, 122, 127, 130, 137, 138, 143, 145, 152

Step 2 : Compute the position of the 90th percentile

position of the 90th percentile, i = (90% × n)

Thus,

i = 0.90 × 12

or

i = 10.8

Now,

Step 3 : Since, the index i is not an integer, round up to the nearest integer

i.e i = 11

Therefore,

The 90th percentile is the value in 11th position,

i.e 145
