Well what's the question? I got a buncha graphs and no question!

Answer:

0.41

Step-by-step explanation:

All probability equals 1. So if the probability that something will happen is x, then the probability that it will not happen is 1-x

Answer:

The real answer is:

3x^2 -6x+3x-6

Step-by-step explanation:

Answer:

(b) 60.21ft^2

Step-by-step explanation:

Given

The attached triangle

Required

Number of square feet materials needed

This simply means that we calculate area;

[tex]Area = 0.5 * base * height[/tex]

[tex]Area = 0.5 * (14ft\ 2in) * (8ft\ 6in)[/tex]

Convert to ft [divide by 12]

[tex]Area = 0.5 * (14+ 2/12) * (8+ 6/12)[/tex]

[tex]Area = 0.5 * (14.17) * (8.5)[/tex]

[tex]Area = 60.23ft^2[/tex]

(B) is correct

Answer:

1.4/10=2/5

2.4/8=1/2

3.8/12=2/3

4.7/5=14/10

5.1/3=2/6

Answer:

192ft squared. But remember it says don't put the square feet so just type in: 192.

Step-by-step explanation:

The top triangle is 42 ft squared.

The rectangle below it is 150 feet squared.

You add them together and get 192 ft squared hope this helps!

Density" of the given granite block is 2.7g/cm

3

.

Explanation:

Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, \rho=\frac{m}{v}ρ=

v

m

where, “m" mass of an object and "v" is volume of an object.

Given that,

Dimensions of the block are 20 cm, 5 cm and 10 cm.

\text { Volume of the block is } l \times b \times h Volume of the block is l×b×h

\text { Volume of the block is } 20 \times 5 \times 10 Volume of the block is 20×5×10

\text { Volume of the block is } 1000 \mathrm{cm}^{3} \text { . } Volume of the block is 1000cm

3

.

Mass of the block is 2700 g.

Substitute the given values in \rho=\frac{m}{v}ρ=

v

m

to find density of a block.

\rho=\frac{2700}{1000}ρ=

1000

2700

\rho=2.7 \mathrm{g} / \mathrm{cm}^{3}ρ=2.7g/cm

3

\text { "Density" of the given granite block is } 2.7 \mathrm{g} / \mathrm{cm}^{3} "Density" of the given granite block is 2.7g/cm

Answer:

The answer is -18

Step-by-step explanation:

He starts off with $100 in his account. He then take so $45 to purchase a pair of jeans, so we have to subtract 45 from 100 and that gives us $55. He now has $55 in his account, he then adds another $25 to his account, so we have to add 25 to 55 and that will give us $80 in his account. Finally on Friday he takes out $98 of his checking account. He takes out more than he has in his checking account so we have to subtract $80 from $98 and we will get $18, but since he takes out more than what he has in his account the answer will be negative and we end up with -18 dollars in his checking account.

Answer:72

Step-by-step explanation:

(4, -1) ---> x = 4 and y = -1

If you look at the graph you can se this

Mark points (0, 2) and (8, -4) in the coordinate plane

Plot the line going through both of these points.

Read the coordinates of the intersection of the line so you can see the solution!

Answer:

(4, 4)

Step-by-step explanation:

So you're trying to find what P' is, and P' would be the dilation of P. This means that you apply the rule (x, y) --> (1/4x, 1/4y) with the coordinate point (16, 16). This would be:

(16, 16) --> (1/4 * 16, 1/4 * 16) = (4, 4)

Complete question:

On the package for a certain brand of spinach seeds there is a guarantee that, if the printed instructions are followed, 63% of planted seeds will germinate. A random sample of 9 seeds is chosen. If these seeds are planted according to the instructions, find the probability that 4 of them germinate.

Answer:

[tex]P(x = 4) = 0.1376[/tex]

Step-by-step explanation:

Given

[tex]n = 9[/tex]

[tex]p = 63\%[/tex] --- proportion that germinates

[tex]p = 0.63[/tex]

Required

P(x = 4)

This question follows a binomial distribution:

[tex]P(x) = ^nC_x*p^x*(1-p)^{n-x[/tex]

When x = 4;

[tex]P(x = 4) = ^9C_4*0.63^4*(1-0.63)^{9-4[/tex]

[tex]P(x = 4) = ^9C_4*0.63^4*(0.37)^5[/tex]

[tex]P(x = 4) = 126*0.63^4*0.37^5[/tex]

[tex]P(x = 4) = 0.13763895392[/tex]

[tex]P(x = 4) = 0.1376[/tex]

Answer:

x=4,y=2

Step-by-step explanation:

3x-2y=8 ..........1

2x+y=10...........2

multiply equation 2 by 2 and adding equation 1 and 2 ,we get

3x-2y=8

4x+2y=20

+_________

7x=28

x=28/7=4

:.x=4

again substituting value of x in equation 1 we get

3×4-2y=8

12-8=2y

y=4/2=2

:.y=2

Answer:

[tex]\theta \approx 1.23^\circ[/tex]

Step-by-step explanation:

The expression has been given as:

[tex]tan(\theta) = \frac{50}{18}[/tex]

Required: Find [tex]\theta[/tex]

Simplify the fraction

[tex]tan(\theta) = 2.7778[/tex]

Take arc tan of both sides

[tex]\theta = tan^{-1}(2.7778)[/tex]

[tex]\theta \approx 1.23^\circ[/tex]
