\bf \cfrac{6}{7}\div \cfrac{36}{56}\implies \cfrac{6}{7}\cdot \cfrac{56}{36}\implies \cfrac{6}{36}\cdot \cfrac{56}{7}\implies \cfrac{1}{6}\cdot 8\implies \cfrac{8}{6}\implies \cfrac{4}{3}

\dfrac{6}{7}\div\dfrac{36}{56}=\dfrac{6}{7}\cdot\dfrac{56}{36}=\dfrac{6}{36}\cdot\dfrac{56}{7}=\dfrac{1}{6}\cdot\dfrac{8}{1}=\dfrac{8}{6}=\dfrac{8:2}{6:2}=\dfrac{4}{3}=1\dfrac{1}{3}

Based on a random sample of 25 units of product X, the average weight is 102 lbs., and the sample standard deviation is 10 lbs.
Alex

Answer:

Step-by-step explanation:

Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.

H_0: \bar x = 100\\H_a: \bar x >100

(Right tailed test)

Given that we assume population is normally distributed

Test statistic:

Mean difference = +2

Std error of sample = \frac{10}{\sqrt{25} } =2

t = test statistic = Mean diff/Std error = 1

degree of freedom= n-1 =24

Critical value of t = 1.711

Our test statistic >1.71

Accept alternate hypothesis

Because there is significant difference between the test statistic and test statistic lies above critical value.

If 1/8(8x+15)24, what is the value of x?
Lelechka [254]

Answer:

x=22.125  or  x=\frac{177}{8}

Step-by-step explanation:

<u><em>The correct equation is</em></u>

1/8(8x+15)=24

solve for x

Multiply by 8 both sides to remove the fraction

(8x+15)=192

subtract 15 both sides

8x=192-15\\8x=177

divide by 8 both sides

x=\frac{177}{8}

x=22.125

1.7(10^−13)(3.5)(10^25)​
liq [111]

\boxed{\bf\huge{Answer:—}}

\sf \longmapsto5.95 \times  {10}^{ 12}

\boxed{\huge\bf{ Solution:—}}

\sf \longmapsto \: (1.7 \times 10  {}^{ - 13} )(3.5 \times  {10}^{25} )

\sf \longmapsto1.7 \times 3.5 ( {10}^{25}   \times  {10}^{ - 13} )

\sf \longmapsto \: 1.7 \times 3.5( {10}^{25 - 13} )

\sf \longmapsto3.5 \:  \times 1.7( {10}^{12} )

\sf \longmapsto5.95 \times  {10}^{ + 12}
