joshua is planting a triangular garden he sketched his diagram measurements are 12m and 10m the questions asks to find the missing side PLZ THIS IS URGENT

Answers

Answer:

It's 16m

Step-by-step explanation:

Let's say the missing side is C, and since the triangle is right-angle triangle, you can use Pythagoras theorem. Which is

C squared is equal to A squared plus B squared

Like this: c^2 = a^2+b^2

Then

c^2= (10)^2 + (12)^2

c^2= 100 + 144

c^2= 244

[tex] \sqrt{244} [/tex]

c = 15.6

Rosie bought a ring in the USA she paid 345 US dollars work out in pounds the amount rosie paid for the ring

Answers

1 Us dollar equals to 0.72 Pound sterling so to convert 345 US dollars to British sterling we’ll need to multiply the amount of dollars by 0.72, so
345 x 0.72 = 248.4
345 us dollars = 248.4 British pounds
Rosie paid 248.4 British pounds for the ring. Hope this helped

A teacher would like to estimate the mean number of steps students take during the school day. To do so, she selects a random sample of 50 students and gives each one a pedometer at the beginning of the school day. They wear the pedometers all day and then return them to her at the end of the school day. From this, she computes the 98% confidence interval for the true mean number of steps students take during the school day to be 8,500 to 10,200. If the teacher had used a 90% confidence interval rather than a 98% confidence interval, what would happen to the width of the interval?

It would increase by 8%.
It would decrease by 8%.
It would increase, but not necessarily by 8%.
It would decrease, but not necessarily by 8%.

Answers

Answer:

It would decrease, but not necessarily by 8%

If the teacher had used a 90% confidence interval rather than a 98% confidence interval, the width of the interval would decrease, but not necessarily by 8%.

Option D is the correct answer.

What is a confidence interval?

A confidence interval is a range of values that is likely to contain the true value of an unknown parameter, such as a population means or proportion, based on a sample of data from that population.

It is a statistical measure of the degree of uncertainty or precision associated with a statistical estimate.

We have,

The width of a confidence interval is determined by the level of confidence and the sample size.

A higher confidence level requires a wider interval, and a larger sample size typically results in a narrower interval.

Since the sample size is fixed in this case, changing the confidence level will result in a change in the width of the interval.

As the confidence level increases, the width of the interval also increases. This is because a higher confidence level requires a larger margin of error, which is added to the point estimate to create the interval.

Therefore,

If the teacher had used a 90% confidence interval rather than a 98% confidence interval, the width of the interval would decrease, but not necessarily by 8%.

The marked price of a radio is Sh. 12600. If the shopkeeper can allow a discount of 15% on the marked price and still make a profit of 25%.At what price did the shopkeeper buy the radio?

Answers

Answer:

13388

Step-by-step explanation:

12600 will be 100% so we want to get at what price its sold when there is a 15%dicount

So will minus 15% from the 100% of the Mp

100%-15%=85%

so if 100%=12600

what about 85%=?

we crossmultiply

85%×12600/100%=10710

so10710 is what the radio will be sold if a 15% dicount is given but we want to get wat price the shopkeeper got in that he made a profit of25%

so if 100%=10710

what about 125%

125%×10710/100%=13387.5 which is 13388/=

Find the length of side x in simplest radical form with a rational denominator

Answers

Answer:

x = 8/√3

Step-by-step explanation:

We solve that above question using the trigonometric function of sin

Sin theta = Opposite/Hypotenuse

Theta = 60°

Opposite = 4

Hypotenuse = x

Hence,

Sin 60 = 4/x

Cross Multiply

sin 60 × x = 4

x= 4/sin 60

in rational form

sin 60 = √3/2

Hence, x = 4/ √3/2

= 4 ÷ √3/2

= 4 × 2/√3

= 8/√3
