I bought 10 bananas. Each bonana weighed 50 grams. If the price for bananas was $6.50 per kilogram, how much did I pay?​

Answer: -1

in a function:

f(x) = mx + b

or

y = mx+ b

y=f(x) so,

y = -(1) x - 3

m=slope --------

x=x-coordinate

b=y-intercept

Answer:

26

Step-by-step explanation:

complementary means two angles that add up to 90 degrees

90-38=52

52÷2=26

to check work you can do 26×2 (since there's 2x) = 52

52+38=90

Using the binomial distribution, it is found that there is a 0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.

The formula is:

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

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

The parameters are:

In this problem:

The probability that exactly 4 out of the first 14 customers buy a magazine is P(X = 4), hence:

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

[tex]P(X = 4) = C_{14,4}.(0.07)^{4}.(0.93)^{10} = 0.0116[/tex]

0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.

Using the combination formula, it is found that there are 37,044 ways to form the soccer team.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

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

In this problem:

Since they are independent of each other, the total number of combinations is given by:

[tex]T = C_{9,3} \times C_{7,4} \times C_{7,3} = \frac{9!}{3!6!} \times \frac{7!}{3!4!} \times \frac{7!}{3!4!} = 37,044[/tex]

Answer:

The toys cost about $12.

Roger should have gotten back about $5.15 in change.

Step-by-step explanation:

Dog Toys Question:

Bone cost $5.25, so you can estimate it to be about $5.

Frisbee cost $6.75, so you can estimate it to be about &7.

To get estimated total, add $5 + $7 = about $12 total.

Roger's Change Question:

The hamburger and fries cost $4.84, so you can round that out to $4.85.

$10 - estimated $4.85 = about $5.15 in change.

You could also round the $4.84 cost of the hamburger and fries to $5 even. In this case, $10 - estimated $5 = about $5 in change.

Answer:

276ft^2

Step-by-step explanation:

A triangular prism is made up of multiple faces, just like any three-dimensional shape. Let's do the calculations for this shape together.

Top two faces: 5ft × 14ft × 2 = 140ft^2 (we multiply by two b/c there are two rectangles, so we save a step)

Front and back face: 8ft × 3ft = 24ft^2 (we do not divide by two b/c there are two triangles, so we save a step)

Bottom face*: 8ft × 14ft = 112ft^2

*Note: Don't solve for this face when calculating latent surface area, or when calculating the SA of a compound shape.

Now, we just add up the areas of all the shapes.

140 + 112 + 24 = 276

Final answer: 276ft^2

Answer:

32π or 100.53 cm^3  to the nearest hundredth.

Step-by-step explanation:

dr/dt = 0.5

V = (4/3)π r^3

So dV/dr = (4/3)* 3 π r^(3-1)

= 4πr^2

Rate of increase in volume:  

dV/dt = dV/dr * dr/dt

At r = 4:

Rate of increase in Volume

dV/dt = 4π(4)^2 * 0.5

= 64π * 0.5

= 32π.

Answer:

D, because the word problem separates the minus nine with a comma.

a is incorrect because there is no cube root

b is incorrect because again, no cube root

c is incorrect because the minus nine should not be within the cube root

Four times the cube root of x, minus nine is [tex]4\sqrt[3]{x-9}[/tex].So, our correct answer is 3. [tex]4\sqrt[3]{x-9}[/tex] .Here are a few ways to write "Four times the cube root of x, minus nine":

4 * √(x) - 9

4√(x) - 9

[tex]4\sqrt[3]{x-9}[/tex]

The first way to write it is the most literal way. It uses the multiplication symbol (*) to indicate that we are multiplying 4 and √(x). The second way to write it is a bit more concise. It uses the exponent notation to indicate that we are taking the cube root of x. The third way to write it is the most mathematical way. It uses the LaTeX symbol for the square root, which is \sqrt{}.Which way you choose to write it depends on the context. If you are writing in a more informal setting, you might use the first way. If you are writing in a more formal setting, you might use the third way
