Results of a blood test are normally distributed with a mean of 6.2 and a standard deviation of 1.5. What is the probability that a patient has a blood test result less than or equal to 8.3?

Answers

Answer:

91.92%

Step-by-step explanation:

Given that:

Mean (μ) = 6.2, standard deviation (σ) = 1.5

Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3

For x = 8.3, the z score is:

[tex]z=\frac{x-\mu}{\sigma}=\frac{8.3-6.2}{1.5} =1.4[/tex]

From the probability distribution table:

P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%

The number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.



There were 10{,}00010,00010, comma, 000 people using the older version of the spreadsheet program when the new version first came out. The number of people still using the older version decreases by 20\%20%20, percent every 666 months.

Answers

Answer:

The decrease in the use of older version is given by,[tex]y = 10000 \cdot0.60^{t}[/tex].

Step-by-step explanation:

It is provided that the number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the number of people still using the version at that time.

The exponential decay function is given as follows:

[tex]y=a(1-r)^{t}[/tex]

Here,

y = final value

a = initial value

r = decay rate

t = time taken

It is provided that there were 10,000 people using the older version of the spreadsheet program when the new version first came out. And the number of people still using the older version decreases by 20% every 6 months.

So, every half-yearly the decrease in the number of people using the older version is 20%. This implies for a year the decay rate is 40%.

Then the decrease in the use of older version is given as follows:

[tex]y=10000(1-0.40)^{t}\\\\y=10000\cdot 0.60^{t}[/tex]

Write the equation of the line in slope intercept form y=mx + b that would have the slope of two and crosses through the ordered pair (-3,5).

Answers

Answer:

y=2x+11

Step-by-step explanation:

Slope is 2

y=2x+b

plug in (-3,5)

5=-6+b

b=11

y=2x+11

Answer:

y = 2x+11

Step-by-step explanation:

y = mx+b where m is the slope and b is the y intercept

We know the slope is 2

y =2x+b

We have a point (-3,5)

Substitute this into the equation

5 = 2(-3)+b

5 = -6+b

Add 6 to each side

5+6 = b

11 =b

The equation is

y = 2x+11

x=70, y=55

The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.

Then use the triangle angle sum theorem and set the equation to 180.

55+55+x=180
110+x=180
x=70

The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.

Which of the following could be the equation of the function below?

On a coordinate plane, a curve crosses the y-axis at y = negative 1.5. It has a maximum at negative 1.5 and a minimum at negative 2.5. It goes through 2 cycles at pi.
y = 0.5 cosine (2 (x minus StartFraction pi Over 2 EndFraction)) + 2
y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2
y = 0.5 cosine (4 (x + pi)) + 2
y = 0.5 cosine (2 (x minus pi)) minus 2

Answers

Answer:

y = 0.5 cosine (4 (x - pi/2)) - 2

Step-by-step explanation:

Taking the general form:

y = A cosine (Bx - Cπ)) + D

In the following case. the constants are:

y = 0.5 cosine (4x - 2π)) - 2

A: 0.5

B: 4

C: 2π

D: -2

The range of this function is:

range = [-|A|+D, |A|+D]

range = [-0.5-2, 0.5-2]

range = [-2.5, -1.5]

Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"

At x = 0, the function value is:

y = 0.5 cosine (4(0) - 2π)) - 2

y = 0.5 - 2 = -1.5

As indicated in "a curve crosses the y-axis at y = negative 1.5"

The period of the function is:

period: 2π/B

period = 2π/4 = π/2 or 2 cycles at π

as described in "It goes through 2 cycles at pi."

Answer:

B) y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2

What is the next term of the geometric sequence?
7, 21, 63

Answers

First find the common ratio of this geometric sequence.

We will use [tex]r = \frac{a2 }{a1 }[/tex].

The second term is 21 and the first term is 7.

So we have [tex]\frac{21}{7}[/tex] and this reduces to [tex]\frac{3}{1}[/tex] or 3.

So, we take the last term in our geometric sequence

and multiply it by the common ratio we just found.

So we have 63 · 3 which is 189.

So the next term in this geometric sequence is 189.

Answer: 189
Explanation:
The rule for this sequence is to multiply by 3.
7•3 = 21
21•3= 63
So the next term would be 189 because,
63•3=189

The number of hours Jonah works depends on how much he earns.

Answers

Answer:

The equation e = 4 h can be used to describe this situation.

Jonah earns $20 to babysit for 5 hours.

Step-by-step explanation:

When Jonah babysits one hour, he earns $7.50.

looking at the graph we see at 1 hour he earns 4 dollars false

The equation e = 4 h can be used to describe this situation.

The slope is 4   so y = 4x   e = 4h  would also work   true

Jonah earns $20 to babysit for 5 hours.

Using our equation from above

e = 4*5 = 20   true

The number of hours Jonah works depends on how much he earns.

This would be false

The dependent variable is on the y axis.  The amount he earns depends on how much he works
