Hello!

I believe the number that can be written in the blank space above is 6.

48+54=6'(8+9)

The number written in the blank space is 6 because when you divide 48 and 54 by their numbers, 8 and 9, you will get an answer of 6 for both numbers.

48/8=6
54/9=6

So the number in the blank space would be 6.

I hope this helps!

Help Plzzz i cant find the answer
Kryger [21]
To solve this, you need to know slope-intercept form;  
y=mx+b  
Where mx is the slope and b is the y-intercept form.  
Now, looking at the values you have been provided, you can just plug them into the formula.  
y= \frac{2}{3}x -2

In an experimental treatment, a random individual scores 51 on a measurement. People in general are normally distributed with a
fiasKO [112]

Answer:

There is significant evidence that treatment will create effect on the subject. Hence We reject H0

Step-by-step explanation:

H0 : μ = 37

H1 : μ ≠ 37

μ = 37 ; σ = 7 ; sample size, x = 51 ; sample size, n = 1

Decision region :

If P value < α ;

Reject H0

Using the Z test statistic :

Zstatistic = (x - μ) ÷ (σ / √n)

Zstatistic = (51 - 37) ÷ (7 / 1)

Zstatistic = 14 ÷ 7

Zstatistic = 2

Obtaining p value from Zstatistic using the p value calculator ;

Zscore = 2 ; 2-tailed test, significance level = 0.05

P value = 0.0455

Zcritical at α = 0.05 for a 2 - tailed test = 1.96

0.0455 < 0.05

There is significant evidence that treatment will create effect on the subject. Hence We reject H0

Solve for x. 2x + 9 = 33 What is the answer?<br><br> A 7.5<br><br> B 12<br><br> C 21<br><br> D 84
Valentin [98]
B, because you subtract 9 from both sides(2x-9 leaves 2x by itself then 33-9=24), which leaves you with 2x=24 the you divide everything by 2 which leaves you with x=12

amid [387]

Answer: Each person will take \dfrac{1}{6} of the pie.

Step-by-step explanation:

Given : One pie is shared equally by 6 people.

The total number of persons = 6

Now, the fraction of the whole pie each person will take :-

\dfrac{\text{Number of pie}}{\text{total persons}}\\\\=\dfrac{1}{6}

Therefore, the fraction of the whole pie each person will take= \dfrac{1}{6}
