Answer:

Step-by-step explanation:

you can use the side angle side formula  ( a form of Law of Cosines)

a^2 = b^2 + c^2 − 2bc cos(A)

where x = a  , then

[tex]x^{2}[/tex] =  [tex]5^{2}[/tex] +[tex]3^{2}[/tex] - 2*5*3*cos(107)

[tex]x^{2}[/tex] = 25 + 9 - 30 * (-0.292371)

[tex]x^{2}[/tex] = 25 + 9 -8.7711511

x = 5.0228 cm

Answer:

[tex]x=\sqrt{41}[/tex]

Step-by-step explanation:

Pythagorean theorem: [tex]a^{2}+ b^{2}=c^{2}[/tex]

Answer:

Option B

Step-by-step explanation:

Pythagorean Theron is:

[tex]a^2+b^2=c^2\\\\\text{a and b - legs}\\\text{c - hypotenuse}[/tex]

We would be solving for 'c', or the hypotenuse.

[tex]4^2+5^2=c^2\\\\16+25=c^2\\\\41=c^2\\\\\boxed{\sqrt{41}, -\sqrt{41} =c}[/tex]

The correct answer should be option B.

Hope this helps.

2x ^7/4

Step-by-step explanation:

Sorry, no explanation.

The representation of the given expression 2[tex]\sqrt[4]{x^{7}}[/tex] will be 2[tex]x^{7/4}[/tex].

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

As per the given expression,

2[tex]\sqrt[4]{x^{7}}[/tex]

Open the radical sign of the above,

2[tex]\sqrt[4]{x^{7}}[/tex] = 2[tex]x^{7/4}[/tex]

Since 7 and 4 are both integers thus they will be rational exponents.

Hence "The representation of the given expression 2[tex]\sqrt[4]{x^{7}}[/tex] will be 2[tex]x^{7/4}[/tex]".

Step-by-step explanation:

To test for Difference in mean times

Null hypothesis, H0 will be, there is no difference in mean times ; m1 = m2

Alternative hypothesis, there is difference in mean times ; m1 ≠ m2

Decision region :

When p value < α ; reject the Null

Here. ;

Pvalue = 2% = 0.02

α = 1% = 0.01

Pvalue > α

0.02 > 0.01

Since, Pvalue > α ; we do not reject the Null ;

Hence, conclusion should be, there is no difference in mean times of bus and car

Because the ratio is how many problems:How much time so it is 2:15

Multiply each side by 5 10:75

So that means 10 problems in 75 minuets.

HOPE THIS HELPED!!!

Answer:

10

Step-by-step explanation:

Set up the following proportion.

2 questions /15 minutes = x questions / 75 minutes.

Notice that both ratios are set up the same way -- questions / time. All proportions are set up the same way.

Mulltiply both sides by 75

2 * 75 / 15 = x

2 * 5 = x

x = 10

She would be able to solve 10 problems in 75 minutes.

The question has missing parameters, as the box plot is not given.

So, I will answer the question using the attached box plot.

Basically, the box plot summarizes 5 data which are:

Minimum, Lower quartile, the Median, the Upper quartile and the Range

So, the summary is as follows:

The first dot on the box plot represents the minimum

[tex]Minimum = 2[/tex]

The first line represents the lower quartile

[tex]Q_1 = 3[/tex]

The mid-line represents the median:

[tex]Q_2 = 6[/tex]

The third line represents the upper quartile:

[tex]Q_3 = 8[/tex]

The last dot represents the maximum

[tex]Maximum = 12[/tex]

From the above data, we can also calculate the range.

[tex]Range = Maximum - Minimum[/tex]

[tex]Range = 12 - 2[/tex]

[tex]Range = 10[/tex]

Answer: 2 days

Step-by-step explanation:

The monkeys eat 3 ²/₃ buckets of bananas each day. Convert this to an improper fraction:

= 3²/₃ = 11/3 buckets per day

The zookeeper bought 7¹/₃ which is:

= 22/3 buckets

To find out the number of days the bananas will last, divide the buckets bought by the buckets eaten per day:

= 22/3 ÷ 11/3

= 22/3 * 3/11

= 66/33

= 2 days

If dividing fractions, multiply by the reciprocal of the second fraction.

Answer:

An appropriate interpretation of the p-value is

E) If the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031

Step-by-step explanation:

A one-sample t-test is used for the comparison between the derived mean of the sample data and the a known mean value, given that the population standard deviation is unknown

The P value indicates the likelihood of obtaining a mean with a value difference from the hypothetical mean which is as much as or more than the difference between the observed mean and the hypothetical

Therefore, an appropriate interpretation of the p-value is if the population mean wait time is 3 minutes then the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.

The option E is correct option which is if the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.

Given-

For the experiment the total customers were selected is 60.

Mean wait time of the experiment is 4.7 minutes.

T-test result in a p-value is 0.00031.

The probability that the population mean wait time is greater than 3 minutes is 0.00031-

Now in the given options the option is E is best interpretation of this pp-test. According to option E, the population mean wait time is 3 minutes the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.

When the t test is performed it is all about the chances of the groups of the experiment results. The time which is taken by a customer in real will be more than this time and thus the probability of observing a sample mean wait time of 4.7 min or more is 0.00031 as the test data suggest.

Hence the option E is correct option which is if the population mean wait time is 3 minutes, the probability of observing a sample mean wait time of 4.7 minutes or more is 0.00031.

Answer:

B.11

Step-by-step explanation:

Two triangles are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.

From the image, CF corresponds to EF, CD corresponds to EG and DF corresponds to GF.

DF = DE + EF = 7 + 5 = 12

Since Triangle CDF is similar to triangle EGF. hence:

[tex]\frac{CF}{EF} =\frac{DF}{GF} \\\\\frac{CF}{5}=\frac{12}{4} \\\\CF=\frac{12*5}{4}\\\\CF=15[/tex]

We can see that:

CF = CG + GF (line segment addition postulate)

CF = x + 4

15 = x + 4

x = 15 - 4

x = 11

Answer:

Step-by-step explanation:

The ratios of side lengths in the given triangle are ...

  1 : √3 : 2 = shortest : middle length : longest

We can make the longest side match the given value if we multiply these numbers by 4√5

  y : x : 8√5 = 1(4√5) : √3(4√5) : 2(4√5) = 4√5 : 4√15 : 8√5

Then we have ...

  x = 4√15

  y = 4√5
