The associative law states that it doesn't matter how we group numbers when we add and/or multiply. So we could rearrange the brackets and parentheses to get the equivalent equation:
9m(6+n)

Both equations total:
54m+9mn
(I applied the distributive property to solve it).

Arturiano [62]

Answer:

13cm

Step-by-step explanation:

104 × 2 = 208

208 ÷ 16 = 13cm

In circle A shown below, the measure of ∠BAD is 148°: Circle A with angle BAD measuring 148 degrees; points B, C, D lie on Circl

german

Answer:

52°

Step-by-step explanation:

In the figure attached, Circle A is shown. There we can see that:

∠BC + ∠CD = ∠BAD

We know that Arc BC measures 96° and arc BAD measures 148°. Replacing this data into the equation and solving for Arc CD, we get:

96° + ∠CD = 148°

∠CD = 148° - 96°

∠CD = 52°

Determine algebraically whether the function is even, odd, or neither even nor odd. f as a function of x is equal to 14 times th

svlad2 [7]

Replace x with -x
if you get same function, function is even
if get negative of original, function is odd
if niehter, then neither

if replace with -x
we get the negattive of it or -14 times cube root of x

answer is it is odd function

A researcher computes r = 0.45 using a sample of 18 participants. Is this Pearson correlation coefficient significant for a two-

Eduardwww [97]

Answer with explanation:

Given : The computed r -value = 0.45

Sample size : n=18

Degree of freedom : $df=n-2=18-2=16$

Now, the critical value for Pearson correlation coefficient for a two-tailed test at a .05 level of significance will be :

$r_c=0.468$ ( by critical correlation coefficient table)

Since , $r>r_c$ i.e. 0.45>0.468 , then we say that his Pearson correlation coefficient is not significant for a two-tailed test at a .05 level of significance.
