Mathematics
1 answer:
NemiM [27]3 years ago
4 0

Answer:

55,98,27

Step-by-step explanation:

To solve for the angles we must first find y with this equation

3y+5+2y-7=153

We can simplify this

5y-2=153

153+2=155

155/5=31

y=31

We now know y and can plug it into the angles

<A=2y-7

2(31)-7

62-7

55

<A=55

<B=3y+5

3(31)+5

93+5

98

<B=98

Now time for the last angle

Since angle BCA and DCB are next to each other they add up to 180

153+x=180

180-153=27

x=27

<BCA=27

Do values of these triangles form right triangles or not using Pythagorean theorem
miskamm [114]

Answer:

Yes

Yes

No

Step-by-step explanation:

9-12-15 is just a dilation of a 3-4-5, which is right.

6-8-10 is also a dilation of 3-4-5.

However, 2-4-6 is not a triangle. In fact, it's just a line segment, because 2+4=6

A​ person's blood pressure is monitored by taking 4 readings daily. The probability distribution of his reading had a mean of 13
ss7ja [257]

Answer:

a) Mean = 133, Standard deviation = 2.5

b) Normal distribution

c) 0.0026

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 4

Mean = 133

Standard deviation = 5

a) Mean and the standard deviation of the sampling distribution of the sample mean for the four observations each day.

The sampling distribution has a mean equal to the population mean

\bar{x} = \mu = 133

The standard deviation of the sampling distribution is given by:

\sigma_s = \dfrac{\sigma}{\sqrt{n}} = \dfrac{5}{\sqrt{4}} = 2.5

b) Shape of the sampling​ distribution

Central limit theorem:

When a large sample is drawn from a normal distribution, then the distribution of sample means approaches a normal distribution.

Since the distribution is normal,  the sampling distribution of the sample mean will be bell shaped and follow a normal distribution.

c) P(sample mean exceeds 140)

P( x > 140) = P( z > \displaystyle\frac{140 - 133}{2.5}) = P(z > 2.8)

= 1 - P(z \leq 2.8)

Calculation the value from standard normal z table, we have,  

P(x > 140) = 1 - 0.9974 = 0.0026

0.0026 is the probability that the sample mean exceeds 140.
