Answer:

The equivalent to -(-5.25) = 5.25

Step-by-step explanation:

Given

$-(-5.25)$

We need to determine the equivalent to -(-5.25)

some of the sign rules are:

+(+) = +

−(−) = +

+(−) = -

−(+) = -

Thus,

$-(-5.25)$

Applying the rule: -a(-a) = a

$=5.25$

Therefore, the equivalent to -(-5.25) = 5.25

Evaluate 3/7r + 5/8s when r= 14 and s= 8

jasenka [17]

Answer:

Step-by-step explanation:

Step 1:

3/7r+5/8s

Step 2:

So u multiply 3/7 by 14

3/7 x 14= 42/7= 6

Step 2.5:

Now u multiply 5/8 by 8

5/8 x 8= 40/8= 5

Find the constant of proportionality and unit rate for the data in the table. Then write the equation to represent the relations

Hatshy [7]

You should set up an X and Y table. Make time X and Distance Y. (the table is like a cross: on the left top put x and left top put y. Then under the line list the x and y numbers given in order.) Then find the "slope" which is y/x (rise over run) then you get the increase rate of 45 mph. The relation between them would be D=45t

At a certain concert, 73 % of the audience was under 20 years old. A random sample of n = 146 members of the audience was select

Tatiana [17]

Answer: p = 0.73

Step-by-step explanation:

Given that,

73% of the audience was under 20 years old :

so, probability (p) = 0.73

n = 146

Mean of the distribution of sample proportion = ?

According to central limit theorem,

np(1-p) ≥ 10

146 × 0.73(0.27) ≥ 10

28.77 ≥ 10

∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.

Hence, the mean of the distribution of sample proportion:

μ = p = 0.73
