Answer:

Step-by-step explanation:

The x-intercept is at (∞, 0)

The y intercept is (0, 1)

The x-intercept of a graph occurs at the point where y = 0

Given the equation y =  5^x

If y = 0

5^x = 0

xln5 = ln 0

x = ln0/ln5

x = ∞

The x-intercept is at (∞, 0)

y-intercept

The y-intercept occurs at the point where x = 0

y = 5^0

y = 1

Hence the y intercept is (0, 1)

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:

In mathematics, the natural numbers are those used for counting and ordering.

Natural numbers include all the whole numbers excluding the number 0. In other words, all natural numbers are whole numbers, but all whole numbers are not natural numbers.

Hi, I'm trying to level up so if you are satisfied with my answer you don't have to but if you could give me brainliest that would be great.

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.

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

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:

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:

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:

Volume of the shape = 1,190 in.³

Step-by-step explanation:

The volume of the shape = volume of the rectangular prism - volume of the right triangle prism

= L*W*H - ½*b*h*l

Where,

L = 20 in.

W = 8 in.

H = 8 in.

b = 3 in.

h = 3 in.

l = 20 in.

Plug in the values

Volume of the shape = 20*8*8 - ½*3*3*20

= 1,280 - 90

= 1,190 in.³

The number of gallons of liquid that Courtney bought is 2 gallons.

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

Given that,

Amount of milk bought = 2 quarts

Amount of orange juice bought = 4 quarts

Amount of apple juice bought = 2 quarts

Total amount of liquid bought = 2 + 4 + 2 = 8 quarts

We have the conversion,

1 quart of liquid = 0.25 gallon of liquid

Total amount of liquid bought in gallons = 8 × 0.25 = 2 gallons

Hence the total amount of liquid bought is 8 gallons.
