When multiplying an odd number of factors,, then that means they will equal a negative. This rule will make this expression change to the following:
-\frac{2}{5}x × 5y × 2x
Now reduce the numbers with 5
-2xy × 2x
Lastly,, calculate the product to get your final answer
-4x²y
This means that your coefficient is -4 and the simplified version of your expression is -4x²y.
Let me know if you have any further questions

Slove:33/29=46/x. Try to find the answer.
Tju [1.3M]

Answer:

x=40\frac{14}{33}

Step-by-step explanation:

we have

\frac{33}{29}=\frac{46}{x}

Solve for x

Multiply in cross

(33)(x)=(46)(29)

Divide by 33 both sides (Division Property of Equality)

x=46(29)/33

x=\frac{1,334}{33}

Convert to mixed number

x=\frac{1,334}{33}=\frac{1,320}{33}+\frac{14}{33}=40\frac{14}{33}

A simple random sample of 44 men from a normally distributed population results in a standard deviation of 10.7 beats per minute
sladkih [1.3K]

Answer:

Step-by-step explanation:

The Hypothesis :

H0 : σ = 10

H1 : σ ≠ 10

The Chisquare statistic, χ² ;

χ² = [(n-1) * s²] ÷ σ²

Sample size, n = 44 ; sample Standard deviation, s = 10.7 ; population standard deviation, σ = 10

χ² = [(44 - 1) * 10.7²] ÷ 10²

χ² = [43 * 114.49] ÷ 100

χ² = [4923.07] ÷ 100

χ² = 49.2307

Using the Pvalue from Chisquare calculator :

degree of freedom, df = n - 1 = 44 - 1 = 43

Pvalue = 0.238
