Answer:

False

Step-by-step explanation:

This is false because A density graph is not used to find the probability of a discrete random variable taking on a range of values. This is because you have to use a calculations instead of a graph. The correct how to calculate is: Determine a single event with a single outcome. Identify the total number of outcomes that can occur. Divide the number of events by the number of possible outcomes.

Therefore, it's B ( false).

Answer:

0.025

Step-by-step explanation:

Mean = 79 ; Standard deviation = 7

P(x ≥ 93)

We obtain the ZSCORE :

Zscore = (x - mean) / standard deviation

x = 93

Zscore = (93 - 79) / 7 = 2

P(Z ≥ 2) = 0.02275

The tools Sami would used to measure the sides and angles of the parallelogram are: compass and ruler.

What is a Parallelogram?

A parallelogram is a type of quadrilateral that has two pairs of opposite sides that are parallel and congruent, and has opposite angles that are also congruent.

A compass ca be used to measure the interior angles while a ruler can be used to measure the side lengths of the parallelogram.

Therefore, the tools Sami would used to measure the sides and angles of the parallelogram are: compass and ruler.

Answer:

Step-by-step explanation:

You have not told us the sort of figure you're supposed to draw. If these are cuboids, then their drawings are substantially similar to the one shown in the attachment. Your figures may need to show the units on each of the dimensions.

1. A cube with edge lengths of 5 m has a volume of ...

  V = s³

  V = (5 m)³ = 125 m³

__

2. A cuboid with the given volume and other dimensions has a length of ...

  V = lwh

  675 cm³ = l(9 cm)(10 cm)

  675 cm³/(90 cm²) = l = 7.5 cm . . . . . . . . divide by the coefficient of l

Answer:

  C.  x -2y = 8

Step-by-step explanation:

One way you can do this is to use the form ...

  (Δy)(x -x1) -(Δx)(y -y1) = 0

where Δx = x2 -x1 = 4 -2 = 2, and Δy = y2 -y1 = -2 -(-3) = 1

This gives ...

  (x -2) -2(y -(-3)) = 0 . . . above form with numbers filled in

You can use any of several other strategies, including finding the slope and y-intercept, then rearranging the equation.

Another strategy that works is to try the answer choices. You might notice that the first given point works in the first equation, so it may make sense to try the second given point in each equation.

The above version of the equation of a line is a variation on one that says the slope of a line is the same everywhere:

  [tex]\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y-y_1}{x-x_1}\ \Rightarrow\ (y_2-y_1)(x-x_1)=(x_2-x_1)(y-y_1)\\\\(y_2-y_1)(x-x_1)-(x_2-x_1)(y-y_1)=0[/tex]

Answer:

C)

Step-by-step explanation:

When you see something like 6³) 2, to get both the exponent and the multiplier together, you must multiply 3 x 2. As this problem goes, there is -7 and 5 as our exponents. If we both multiply them by 2, we will get -14 and 10. Its one of the rules in basic algebra. Check the pic I posted below.

Answer:

[tex]P(x > 0.28) = 1[/tex]

Step-by-step explanation:

Given

[tex]p = 33\%[/tex] --- orders from first time customer

[tex]n =163[/tex] --- samples

Required

[tex]P(x >0.28)[/tex]

First, calculate the mean

[tex]\bar x = np[/tex]

[tex]\bar x = 163 * 33\%[/tex]

[tex]\bar x = 53.79[/tex]

Next, the standard deviation

[tex]\sigma = \sqrt{\bar x * (1 - p)[/tex]

[tex]\sigma = \sqrt{53.79* (1 - 33\%)[/tex]

[tex]\sigma = \sqrt{53.79* (1 - 0.33)[/tex]

[tex]\sigma = \sqrt{53.79* 0.67[/tex]

[tex]\sigma = 6.00[/tex]

For [tex]P(x >0.28)[/tex],

The z score is:

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

[tex]z = \frac{0.28 - 53.79}{6}[/tex]

[tex]z = \frac{-53.51}{6}[/tex]

[tex]z = -8.92[/tex]

So:

[tex]P(x > 0.28) = P(z > -8.92)[/tex]

From z probability:

[tex]P(z > -8.92) =1[/tex]

Hence:

[tex]P(x > 0.28) = 1[/tex]

Answer:

26.6degrees

Step-by-step explanation:

Given

percent grade through north = 10% (opposite)

percent grade through east = 20% (adjacent)

Get the direction

Using the SOH CAH TOA identity

tan theta = opp/adj

tan theta = 10/20

tan theta = 0.5

theta = arctan (0.5)

theta = 26.6degrees

Hence the required angle is 26.6degrees

Answer:

Step-by-step explanation:

The amortization formula can be used to find the payment value.

  A = P(r/2)/(1 -(1 +r/2)^(2n))

where P is the principal amount at the beginning of the loan period, r is the annual interest rate, n is the number of years remaining on the loan

The value of A in this scenario is the semi-annual payment.

Initially, the interest rate is 0.055 and the number of years remaining is 25.

After the first 5-year period, the interest rate goes up by 12%, so is multiplied by a factor of 1.12 to become 6.16% per year. The same growth factor is applied to the interest rate at the beginning of each 5-year period.

Of course, the number of years remaining is decreased by 5 years at the beginning of the next 5-year period.

__

The Principal remaining at the end of each 5-year period is the starting principal for the next period. It is calculated from ...

  FV = P(1 +r/2)^10 -A((1 +r/2)^10 -1)/(r/2)

Where P is the starting principal, A is the loan payment as calculated above, and r is the annual interest rate.

__

These formulas are built into spreadsheet functions, so the desired set of loan payments can be calculated easily by that technology. The result is attached. In the "# pmts" column is the value used to amortize the loan for the 5-year period. The semiannual payment is calculated as though the loan would be completely paid off in that number of payments, keeping the same interest rate for the duration. Of course, that payment series is interrupted and the loan recalculated at the beginning of the next 5 years.

The half-yearly payments for each 5-year interval are ...

  $33,336.83

  $35,176.68

  $36,869.23

  $38,266.75

  $39,158.08

Additional comment

The values displayed in the spreadsheet are rounded to the values shown. The values used in calculation have 14 or more significant digits. This means the numbers here may vary from those provided by a lending institution. In the real world, the principal and interest values are rounded to cents with each payment, so actual results may vary by a few cents either way.

Answer:

y = 27

Step-by-step explanation:

The sum of the two angles is a right angle, which is 90 degrees

y+63 = 90

y = 90-63

y =27

Answer:

The measures of angle y is 30 °.

Step-by-step explanation:

We know that, the sum of two side of right angle is 90 °.

60 ° + y = 90 °

subtract 60 ° from each side

y = 90 ° - 60

y = 30 °

Therefore, the measures of angle y is 30°.

Answer:

He can have 40 guinea pigs in the store.

Step-by-step explanation:

Since Jonas runs a pet store that sells guinea pigs, and he wants to ensure he has more than 1 pound of dry food for every five guinea pigs he has in the store, and he currently has 8 pounds of dry food, to know how many guinea pigs can he have in the store, the following equation must be performed:

1 = 5

8 = X

8 x 5 = X

40 = X

Therefore, he can have 40 guinea pigs in the store.

Answer:

The distance from the store A to the warehouse is of 13.93 miles.

Step-by-step explanation:

The delivery truck drove 5 miles from store A to store B

5 miles south.

13 miles from store B to the warehouse.

13 miles east.

The situation can be represented by:

A

B         Warehouse

In which the distance of A to B is of 5 miles, and the distance of B to the warehouse is of 13 miles. Thus, the distance of store A to the warehouse is the hypothenuse of a right triangle, with sides 5 and 13.

Using the Pytagorean Theorem:

[tex]h^2 = 5^2 + 13^2[/tex]

[tex]h^2 = 25 + 169[/tex]

[tex]h^2 = 194[/tex]

[tex]h = \sqrt{194}[/tex]

[tex]h = 13.93[/tex]

The distance from the store A to the warehouse is of 13.93 miles.
