28/8 or 7/2 is the answer to that

Anit [1.1K]3 years ago

3 0

To achieve this you need to make the whole number a fraction
To do this you simply put it over one
So 7/1x4/8
Then find common denominators
Then multiply
Then simplify into smallest form
You should get 7/2

Francine applies the commutative property to the product. (−8/9)⋅(−13)⋅(18) Which expression illustrates the commutative propert

oksian1 [2.3K]

The commutative property implies that, the order of multiplication is not important.

$(-\frac 89) \cdot (18) \cdot (-13)$ is true

Commutative property of multiplication states that:

If $a \times b = b \times a$

The expression is given as:

$(-\frac 89)\cdot (-13) \cdot (18)$

To get the commutative expression, we simply change the position of each factor in the expression.

So, some possible equivalent expressions are:

$(18) \cdot (-13) \cdot (-\frac 89)$

$(18)\cdot (-\frac 89) \cdot (-13)$

$(-13) \cdot (18) \cdot (-\frac 89)$

There are several other equivalent expressions.

From the list of options;

$(-\frac 89) \cdot (18) \cdot (-13)$ is true

Find 4 consecutive odd numbers such that twice the sum of the least 2 numbers is 40 less than three times the sum of the greates

ANTONII [103]

4 consecutive odd numbers....x, x + 2, x + 4, x + 6

2(x + x + 2) = 3(x + 4 + x + 6) - 40
2(2x + 2) = 3(2x + 10) - 40
4x + 4 = 6x + 30 - 40
4x + 4 = 6x - 10
4x - 6x = -10 - 4
-2x = - 14
x = -14/-2
x = 7

x + 2 = 7 + 2 = 9
x + 4 = 7 + 4 = 11
x + 6 = 7 + 6 = 13

ur numbers are : 7,9,11,13 <==

A gambler claims that horses in a horse race that start closer to the rail have an advantage over horses that start further from

k0ka [10]

Answer:

Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS

there is no significant evidence that starting position is a factor in horse races

Step-by-step explanation:

Given the data in the question;

Starting position: 1 2 3 4 5 6

# of Winners: 25 22 18 19 21 15

Mean x" (E) = (25+22+18+19+21+15)/6 = 120/6 = 20

Observed/Expected value table;

O E ((O-E)²) / E

25 20 1.25

22 20 0.2

18 20 0.2

19 20 0.05

21 20 0.05

15 20 1.25

∑ 3

so using chi square = ∑(((O-E)²) / E) = 3

DF = n-1 = 6-1 = 5

then, the critical chi square value is;

significance level = 0.05

chi square( critical ) = 11.07049769

from table;

p - value = 0.699986

Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS

there is no significant evidence that starting position is a factor in horse races

Factor.<br> x^2 - 8x +16

galben [10]

This is a perfect square trinomial. All of these special cases take this form which you can identify: a²+2ab+b².

x^2 - 8x +16 equals (x-4)²

answer: (x-4)²
