Where,

P=principal=$20,000

r=Interest rate=7.77%=7.77/100

Answer:

Step-by-step explanation:

The probability is obtained by calculating the z score,  

(pˆD−pˆE) - (PD - PE)

      0.0914  

10.1917-0.1

0.0914           = 1.0029

P(z > 1.0029) = 1 - P(z ≤ 1.0029)

The probability is obtained from the z distribution table,

P(Z > 1.0029) = 1-0.8420 = 0.1580

Distribute the 2 through the parentheses

on the right side of the equation.

2(y) is 2y and 2(2) is 4.

So the problem now reads 6 = 2y + 4.

Now we can subtract 4 from both

sides of the equation to get 2 = 2y.  

Now divide both sides of the

equation by 2 and 1 = y.

Answer:

12

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 9)² + (y - 4)² = 36 ← is in standard form

with r² = 36 ⇒ r = [tex]\sqrt{36}[/tex] = 6

diameter = 2 × r = 2 × 6 = 12

Answer:

In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean.

To calculate the standard deviation of those numbers:

Work out the Mean (the simple average of the numbers)

Then for each number: subtract the Mean and square the result.

Then work out the mean of those squared differences.

Take the square root of that and we are done!

The minimum length of a table that is 3 feet wide to have at least 24 square feet of space is found by solving the inequality 3L ≥ 24, which results in a minimum length of 8 feet.

The question involves finding the minimum length of a table to achieve a certain area, which requires understanding and solving an inequality. Given that the table is 3 feet wide and we need at least 24 square feet of space, we can set up the inequality as follows:

Let L be the length of the table in feet.

The area A of a rectangle is calculated as A = length × width.

Thus, A = L × 3 square feet.

To satisfy the condition of having at least 24 square feet, we have the inequality 3L ≥ 24.

Dividing both sides by 3 to solve for L, we get L ≥ 8.

Therefore, the minimum length the table should have is 8 feet.

The height of Joseph in meters is 1.79 m.

Height, altitude, elevation mean vertical distance either between the top and bottom of something or between a base and something above it. Height refers to something measured vertically whether high or low.

Here, Height of Joseph = 5.9 ft.

         1 feet = 0.304 m

        5.9 ft = 0.304 X 5.9 m.

        5.9 ft = 1.79 m.

Thus, the height of Joseph in meters is 1.79 m.

Answer:

C

Step-by-step explanation:

Total number of notebooks and pencils= 19

Assuming that she bought notebooks only,

amount spent

= 19($2.05)

= $38.95

Difference in actual amount spent

= $38.95 -$31.80

= $7.15

This difference in amount is due to the number of wrong assumptions we have made previously, such that we assumed that a certain number of pencils that she bought was notebooks. Thus, let's find the number of wrong assumptions so we can find out how many pencils she bought.

Cost difference of each notebook compared to a pencil

= $2.05 -$1.50

= $0.55

This means that for each wrong assumption, there is an additional $0.55 in the total amount Joanna spent.

Number of sets of extra $0.55

= $7.15 ÷$0.55

= 13

Thus, she bought 13 pencils.

Amount of notebooks bought

= 19 -13

= 6

Let's check our work!

If Joanna bought 13 pencils and 6 notebooks,

total amount spent

= 13($1.50) +6($2.05)

= $19.50 +$12.30

= $31.80

Thus option C is indeed correct as it is given from the question that she spent $31.80.

Answer:  Armando used the wrong dimensions for the triangular prism.

Step-by-step explanation:

Hi, to answer this question we have to analyze Armando’s work.

Total Volume = Volume of rectangular prism + volume of triangular prism  

Total Volume = 5 (8) (18) + one-half (6) (18) (8)  

Total Volume= 720 + 432  

Total volume = 1,152 cubic inches.

He made a mistake in the second step, where used h=8 for the triangular prism instead of h= 5 . (h=height)

The correct way to solve this is.

Total Volume = 5 (8) (18) + one-half (6) (18) (5)  

Total Volume= 720 + 270

Total volume = 990 cubic inches.

Answer: $7,81; $4.78 per mile

Step-by-step explanation:

To get the cost per mile we have to divide 9,500 by the cost.

(The total cost annual was $3,200)

9,500 divided by $1,215 = $7.81

9,500 divided by $1,985 = $4.78

Answer:

15..

Step-by-step explanation:

4, 10, 14, 18, 22, 22

Mean = (4 + 10 + 14 + 18 + 22 + 22)/6

= 90/6

= 15.

Number to be added, 'y'

For the mean to be the same

(90 + y) / 7 = 15

90 + y = 15 × 7

90 + y = 105

y = 105 - 90

= 15

Answer:

Hi there! The answer is B: 45 Miles/Hour (or mph)

Step-by-step explanation:

When looking at speed signs in the U.S. they always use miles per hour, or MPH. Making it so the other options are incorrect!

Hope this helps!! :)

The most common unit on a U.S. speed limit sign is B. 45 miles/hour. Speed limits are displayed in miles per hour, not in units like miles per day, miles per second, or feet per second.

The value you would most likely see on a U.S. speed limit sign is B. 45 miles/hour. In the U.S., speed limits are almost always shown in miles per hour (mi/h). Therefore, options like 150 miles/day, .08 miles/second, or 25 feet/second are not standard measurements for speed limits on road signs.

To address the conversion exercises, converting 80 km/h to metric units of meters per second (m/s), you use the conversion factor 1 km/h = (1/3.6) m/s. So, 80 km/h equals approximately 22.2 m/s. The conversion to imperial units of miles per hour requires knowing that 1 km is roughly 0.621 miles, making 80 km/h about 49.7 mi/h.

Similarly, 100 km/h equals about 27.8 m/s (not an option here), and in miles per hour, it's approximately 62 mi/h. When converting from metric to imperial or vice versa, it's useful to remember that 1 m/s equals 3.6 km/h and roughly 2.2 mi/h.

Answer:

A' = 2,-2

B' = 2,-4

C' = 5,-4

Step-by-step explanation:

By calculating angles and side lengths using trigonometric ratios and the Pythagorean theorem, we determined that the height of the silo (length CE) is approximately 18 feet.

Calculate angle ACD using the tangent trigonometry ratio:

Given AD = 8 feet and DP = 5 feet, we find C using tan(C) = AD/DP, which gives C = arctan(8/5) = 32 degrees.

Calculate angle BCA:

BCA = 90 - 32 = 58 degrees.

Calculate side length AC using the Pythagorean theorem:

Given AB = 5 feet and BC = 8 feet, AC^2 = AB^2 + BC^2, so AC = sqrt(89) = 9.4 feet.

Calculate the height of the silo (length CE) using the cosine ratio:

With AC = 9.4 feet and BCA = 58 degrees, cos(58) = BC/AC = CE/9.4. Solving for CE, we get approximately 17.7 feet.

Therefore, the height of the silo is approximately 18 feet.

The total surface area of the triangular prism will be 14 square centimeter.

Option C is correct.

Total surface area :

From the  given diagram of  triangular prism,

It is observed that, The total surface area of the triangular prism will be the summation of area of two triangle and area of large rectangle.

Area of one triangle =(1/2)*3*2 = 3  square centimeters

So that, area of both triangle =2 * 3=6 square centimeters

Area of large rectangle=(2.5+3+2.5)*1=8*1=8 square centimeters

total surface area of the triangular prism =8+6=14 square centimeters

Therefore, total surface area of the triangular prism is 14 square centimeters.

Answer:

A) ∠D ≅ ∠F

Step-by-step explanation:

Supplementary angles : A pair of angles whose sum is 180° are called supplementary angles

We are given that ∠D is a supplementary angle of ∠E

So,[tex]\angle D+\angle E = 180^{\circ} -----1[/tex]

We are also given that ∠F is a supplementary angle of ∠E

So,[tex]\angle F+\angle E = 180^{\circ} ------2[/tex]

Find the value of ∠E form 1 and 2

From 1 : [tex]\angle E = 180^{\circ}-\angle D[/tex]

From 2 : [tex]\angle E = 180^{\circ}-\angle F[/tex]
