Answer:

x = 9.2

x =22.0

x = 8.7

Step-by-step explanation:

Required

Find x

(a)

x is calculated using tangent formula

\tan(57) = \frac{x}{6}

Make x the subject

x = 6 * \tan(57)

x = 6 * 1.5399

x = 9.2394

x = 9.2 --- approximated

(b):

x is calculated using cosine formula

\cos(60) = \frac{11}{x}

Make x the subject

x = \frac{11}{\cos(60)}

x = \frac{11}{0.5}

x =22.0

(c):

x is calculated using sine formula

\sin(60) = \frac{x}{10}

Make x the subject

x = 10 * \sin(60)

x = 10 * 0.8660

x = 8.660

x = 8.7 --- approximated

Lapatulllka [165]
No because if you divide 1.25 by two to find out what the half is in 2.5, it would be .62… and since she wants to buy 2.5 pounds, you've already figured out the .5, so 1.25x2 + .62, it would be 3.12.

riadik2000 [5.3K]

Answer:

Option b - not significantly greater than 75%.

Step-by-step explanation:

A random sample of 100 people was taken i.e. n=100

Eighty of the people in the sample favored Candidate i.e. x=80

We have used single sample proportion test,

p=\frac{x}{n}

p=\frac{80}{100}

p=0.8

Now we define hypothesis,

Null hypothesis H_0 : candidate A is significantly greater than 75%.

Alternative hypothesis H_1 : candidate A is not significantly greater than 75%.

Level of significance \alpha=0.05

Applying test statistic Z -proportion,

Z=\frac{\widehat{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n}}}

Where, \widehat{p}=80\%=0.80 and p=75%=0.75

Substitute the values,

Z=\frac{0.80-0.75}{\sqrt{\frac{0.75(1-0.75)}{100}}}

Z=\frac{0.80-0.75}{\sqrt{\frac{0.1875}{100}}}

Z=\frac{0.05}{0.0433}

Z=1.1547

The p-value is

P(Z>1.1547)=1-P(Z

P(Z>1.1547)=1-0.8789

P(Z>1.1547)=0.1241

Now, the p-value is greater than the 0.05.

So we fail to reject the null hypothesis and conclude that the A is not significantly greater than 75%.

Therefore, Option b is correct.
