Patty wanted to borrow $20,000 for school. The interest rate is 6%. She wants to pay off the loan in 10 years. What would be the simple interest rate?

Answer:

69.75

Step-by-step explanation:

Answer:

Step-by-step explanation:

Because the y intercept is two our y=mx+b equation looks like this

y=mx+2

We then need to find a slope that gives us an x intercept of 3 or satisfies the coordinates of (3,0)

We can plug this in and solve

0=3m+2

-2=3m

-2/3=m

which means our final equation is

-2/3x+2

Answer:

a) 179 people shopped at the grocery store or the drug store.

b) 21 people shopped at neither the grocery store nor the drug store

Step-by-step explanation:

I am going to treat these events as Venn sets.

I am going to say that:

Set A: Shopped at the grocery store

Set B: Shoped at the drug store.

121 shopped at the grocery store:

This means that [tex]A = 121[/tex]

91 shopped at the drug store:

This means that [tex]B = 91[/tex]

33 shopped at both businesses.

This means that [tex]A \cap B = 33[/tex]

a) How many people shopped at the grocery store or the drug store?

This is

[tex]A \cup B = A + B - (A \cap B)[/tex]

With the values given in the exercise.

[tex]A \cup B = A + B - (A \cap B) = 121 + 91 - 33 = 179[/tex]

179 people shopped at the grocery store or the drug store.

b) How many people shopped at neither the grocery store nor the drug store?

179 of 200 shopped in at least one. So 200 - 179 = 21 shopped at neither.

21 people shopped at neither the grocery store nor the drug store

Answer:

$14.7

Step-by-step explanation:

Given: Total = $58.80, Tax = $5.20

To find: The price of each CD before tax

Solution: The total price of the 4 CDs can be determined first by subtracting the tax from the total paid;  

$58.80 - 5.20 = $53.6

To find the price of each CD before tax, divide $58.80 by  4:

$58.80 ÷ 4 = $14.7

The price of each CD was $14.7 before tax.

Answer:

0.8746 = 87.46% probability of at least 6 failures in 7 trials.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

7 trials

This means that [tex]n = 7[/tex]

The probability of success in any trial is 9%​?

So the probability of a failure is 100 - 9 = 91%, which means that [tex]p = 0.91[/tex]

Probability of at least 6 failures in 7 trials?

This is:

[tex]P(X \geq 6) = P(X = 6) + P(X = 7)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 6) = C_{7,6}.(0.91)^{6}.(0.09)^{1} = 0.3578[/tex]

[tex]P(X = 7) = C_{7,7}.(0.91)^{7}.(0.09)^{0} = 0.5168[/tex]

[tex]P(X \geq 6) = P(X = 6) + P(X = 7) = 0.3578 + 0.5168 = 0.8746[/tex]

0.8746 = 87.46% probability of at least 6 failures in 7 trials.

Answer:

Step-by-step explanation:

Whole numbers are numbers such as 0, 1, 2, 3, 4. Irrational numbers are numbers that cannot be represented as a ratio, such as [tex]\sqrt{2}[/tex]. The first one would be false.

Rational numbers are numbers that can be represented as a ratio, like [tex]\frac{4}{5}[/tex] or [tex]\frac{2}{1}[/tex]. Because 4/5 is not a whole number but is a rational number, the second one would be true.

Irrational numbers are numbers that cannot be represented as a ratio. Because integers can be represented as a ratio, since integers are numbers like -2, -1, 0, 1, 2, etc, all irrational numbers are not integers and, therefore, the third one is false.

Using the definition of rational numbers and integers from responses two and three, respectively, this fourth one is false.  

Answer:

52cm^2

Step-by-step explanation:

6*3+2((2*5)/2)+4*6

=18+10+24

=52

Answer:

77cm²

Step-by-step explanation:

Okay, so first you have to find the area of all the shapes that make up the net, I'm going to start with the triangle:

So the height is 2 and the base is 5, so we plug this into our equation to get:

2 x 5 ÷ 2 = 5

There's 2 triangles so:

5 x 2 = 10

Then we start on the rectangles, we're going left to right:

6 x 3 = 18

5 x 5 = 25

4 x 6 = 24

Then we add that all up:

10 + 18 + 25 + 24 = 77

So the net of the triangular prism is 77cm²

hope this helps:)

Answer:

La media es 24

Step-by-step explanation:

La media se obtiene al sumar todos los numero y despues dividirlos entre la cantidad de numeros q son :

26+26+26+26+26+26+25+25+25+25+24+24+23+23+23+22+22+21+21+21 = 480

Despues.......

480÷20 = 24

( es entre 20 por q son 20 numeros )

Answer:

24

Para encontrar la media, sume todos los números y divida por el número de números dados.

Step-by-step explanation:

26+ 26+ 26+ 26+ 26+ 26+ 25+ 25+ 25+ 25+ 24+ 24+ 23+ 23+ 23+ 22+ 22+ 21+ 21+ 21​= 480

480 dividido 20 = 24

Step-by-step explanation:

so first i did 180-76=104, then i did 104/2=52  

then i do a random number times 4, 4x9=36, so then i did 4x13=52,  so s=13

Answer:

The suggestion proposed considering special cases, so that’s what we’ll do.

One special case we could consider is when x=0. If h=r, then we have a hemisphere. You may have learnt that the surface area of a sphere is 4πr2, so the answer in this case is 2πr2. Likewise, we can consider the most extreme cases: when h=2r, we get an area of 4πr2 (the entire sphere), and when h=0, we get zero area.

So if we do manage to get a general formula, we will be able to check it in these special cases.

Another possible idea when x=0 is to consider what happens when h is very small. In this case, the surface area looks a lot like a circle, but the radius of the circle does not seem particularly easy to work out, so maybe we’ll leave this one for a moment. (There are things we can do to approximate the radius using more advanced techniques, but they are currently beyond us.)

Another thing we could consider is the situation where h is very small. Then the part of the sphere between the planes looks very much like the frustum of a cone, and we know how to find the (surface) area of such a shape – see Cones.

If we recall our answer from that problem, we find the formulae for the surface area

π(R+r)s=π(R+r)hcosθ=π(R2−r2)sinθ.

Here, R is the radius of the base of the frustum, r is the radius of the top, h is the perpendicular height, s is the slant length and θ is the angle the slant makes with the vertical.

Hello your question is incomplete below is the missing value

determine the probability that the number who have a high school degree as their highest educational level is exactly 32

answer : P( x = 32 ) = 0.08

Step-by-step explanation:

Given ;

n = 100 , p = 0.304

np = 100 * 0.304 = 30.4

n( 1 - p ) = 100 ( 1 - 0.304 ) = 69.6

applying normal approximation to the Binomial to determine mean value and standard deviation ( because:  np and n(1-p)  > 5 )

mean = np = 30.4

std = [tex]\sqrt{np(1-p)}[/tex] = [tex]\sqrt{30.4(69.6)}[/tex] = 4.6

Determine the probability of exactly 32

P( X = 32 ) = P( 31.5 < X < 32.5 )

                 = P( (31.5 - 30.4) / 4.6  < X  < (32.5 - 30.4) / 4.6 )

                 = P ( 0.24 < Z < 0.46 )

                 = p( Z < 0.46 ) - p( Z< 0.24 )   ( using standard tables )

                 = 0.6772 - 0.5948 = 0.0824  ≈ 0.08

Answer:

m = -22

Step-by-step explanation:

Formula for parabola in it's vertex form is given by;

y = a(x - h)² + k

Where (h, k) is the coordinate of the vertex.

We are told that vertex is at (-6, 6) and the roots are at 10 and m.

Thus;

y = a(x - (-6))² + 6

y = a(x + 6)² + 6

Since 10 is a root, thus;

0 = a(10 + 6)² + 6

-6 = 256a

a = -6/256

a = -3/128

Thus,the equation is;

y = (-3/128)(x + 6)² + 6

Since m is a root, then;

0 = (-3/128)(m + 6)² + 6

-6 = (-3/128)(m + 6)²

Rearranging, we have;

128 × 6/3 = (m + 6)²

256 = m² + 12m + 36

m² + 12m - 256 + 36 = 0

m² + 12m - 220 = 0

Using quadratic formula, we have;

m = 10 or -22

Answer:

240 feet

Step-by-step explanation:

Given that,

The object falls 400 feet in 5 seconds.

We need to find how far it fall in 3 seconds.

5 seconds = 400 feet

1 second = 80 feet

So,

In 3 seconds,

d = (80×3) feet

= 240 feet

So, it will fall 240 feet in 3 seconds.
