Answer:

Option B is the correct answer.

Step-by-step explanation:

We have one side = 27.6 cm

Hypotenuse = 30 cm

Length of remaining side =\sqrt{30^2-27.6^2}=11.76cm

Area of right angled triangle =\frac{1}{2}\times \texttt{Product of lengths of 2 sides other than hypotenuse}

Area =\frac{1}{2}\times 27.6\times 11.76=161.7cm^2

Option B is the correct answer.

juin [17]

Answer:

Standard deviation 46.3

Step-by-step explanation:

A 28% of the distribution is equivalent to a z score of -0.5828, you can use a z table to find that.

Z score is calculated as follows:

z = \frac{x-\mu}{\sigma}

x is the number being evaluated

μ is the mean

σ is the standard deviation

And it is used to calculate how many standard deviations you are from the mean of the sample.

Replacing with the known information you can calculate the standard deviation:

\sigma=\frac{x-\mu}{z} =\frac{76-103}{-0.5828}= 46.3

The triangle below has been reduced by a scale of 0.4. A large triangle has a base of 30 centimeters and height of 10 centimeter
egoroff_w [7]

Answer:

24 centimeters squared(cm²)

Step-by-step explanation:

The triangle below has been reduced by a scale of 0.4.

A large triangle has a base of 30 centimeters and height of 10 centimeters.

Hence, reducing the large triangle by the given scale ratio, we have :

Height = 10cm × 0.4 = 4cm

Base = 30cm × 0.4 = 12 cm

Hence, the area of the smaller triangle

= Area = 1/2 × Base × Height

Height = 4 cm

Base = 12 cm

Area = 1/2 × 4 × 12

= 24 cm²

Determine the value of base x if (211)x = (6A)16
igor_vitrenko [27]
211_x=2x^2+x+1
6A_{16}=106_{10}

\implies 2x^2+x+1=106\iff 2x^2+x-105=(x-7)(2x+15)=0

This has two solutions, x=7 and x=-\dfrac{15}2.
