What is the answer for -7 x 7 please say the explanation too.

Answers

-7 x 7 = -49

We can first figure out 7 x 7, which will be 49. Once we have that, we can look at our negatives. If we have an odd number of negative signs, the answer will be negative. If we have an even number of negative signs, the answer will be positive. In this case, we only have 1 negative sign, and 1 is odd, therefore our answer will be odd.

Answer:

A = 14 in²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 7 and h = 4 , then

A = [tex]\frac{1}{2}[/tex] × 7 × 4 = [tex]\frac{1}{2}[/tex] × 28 = 14 in²

if a circle’s circumference is decreased by12% what percent is the diameter decreased by?


A) 2√3 %
b) 6 %
C) 12 %
D)24%

Answers

Answer:

A) 12%

Step-by-step explanation:

Lets assume a random diameter to work with. I will use a diameter of 10.

Circumference = πD

Circumference = π * 10

Circumference = 31.415

Decreasing the circumference by 12%

31.415 * 0.12 = 3.769

31.415 - 3.769 = 27.64

To find out what percent the diameter is reduced by we will find out the new diameter with the new circumference

Circumference = πD

27.64 = π * D

D = 27.64 / π

New Diameter = 8.8

OldD - NewD

10 - 8.8 = 1.2

1.2/10 = 0.12

The diameter decreased by 12%

The diameter of the circle decreased by 12% due to decrease of circles circumference by 12%.

What is a circle?

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

The diameter is the longest line that can be drawn inside a circle.

Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.

Let's say the diameter of the circle is D

Circumference of circle = πD

12% of Circumference = (12/100) × πD

⇒ 0.12πD

So new circumference will be

πD -  0.12πD = 0.88πD

Now let say new diameter after decreasing circumference is d

Circumference of new circle will be

πd = 0.88πD

d = 0.88D

% decrement = (change/original) × 100

diameter decrease = (D - 0.88D)/D × 100

12% hence it will be correct answer.

Step-by-step explanation:

Recall cos2x=cos^2x-sin^2x

Or cos2x=cos^2x-(1-cos^2x)*

Or cos2x=2cos^2x-1**

*By a Pythagorean Identity

**Combined like terms

I'm going to use third identity from above because I only have to find cosx or cos^2x to get requested answer for cos2x.

Recall Pythagorean identity 1+tan^2x=sec^2x.

Plug in our tangent valuem...

1+(9/8)^2=sec^2x

Given:

The probability distribution table:

x     :      0               1               2                3

p(x) :   0.25         0.15          0.05          0.55

To find:

The mean of this probability distribution.

Solution:

The formula for mean of a probability distribution is:

Using this formula, we get

[tex]Mean=0\cdot 0.25+1\cdot 0.15+2\cdot 0.05+3\cdot 0.55[/tex]

13 A traffic roundabout has a circular garden
in the centre and two lanes for traffic
encircling the garden. The diameter of the
garden is 16 metres and each lane is 3 metres
wide. Each lane is to be resurfaced. Calculate
the area to be resurfaced. Answer in square
metres to the nearest whole number.

Answers

Answer:

Step-by-step explanation:

The area to be resurfaced is the area of the

whole circle including garden and lanes minus  

the area of the garden.

 

Area of a circle is (pi)r2

 

radius of garden is (1/2)diameter = 8 m

Garden area:  (pi)82 = 64(pi) m2

 

Diameter of garden plus traffic lanes is

16 + 2(6) because we add 6 m to both sides

of the diameter of the garden.

Full diameter = 16+12 = 28 m

Full radius = 28/2 = 14 m

Full area:  (pi)142 = 196(pi) m2

 

Area to be resurfaced:

196(pi) - 64(pi) = 132(pi) m2  ≅ 415 m2

he radioactive element​ carbon-14 has a​ half-life of 5750 years. A scientist determined that the bones from a mastodon had lost 77.8 ​% of their​ carbon-14. How old were the bones at the time they were​ discovered?

Answers

Answer:

The bones were 12,485 years old at the time they were​ discovered.

Step-by-step explanation:

Amount of the element:

The amount of the element after t years is given by the following equation, considering the decay rate proportional to the amount present:

[tex]A(t) = A(0)e^{-kt}[/tex]

In which A(0) is the initial amount and k is the decay rate, as a decimal.

The radioactive element​ carbon-14 has a​ half-life of 5750 years.

This means that [tex]A(5750) = 0.5A(0)[/tex], and we use this to find k. So

[tex]A(t) = A(0)e^{-kt}[/tex]

[tex]0.5A(0) = A(0)e^{-5750k}[/tex]

[tex]e^{-5750k} = 0.5[/tex]

[tex]\ln{e^{-5750k}} = \ln{0.5}[/tex]

[tex]-5750k = \ln{0.5}[/tex]

[tex]k = -\frac{\ln{0.5}}{5750}[/tex]

[tex]k = 0.00012054733[/tex]

So

[tex]A(t) = A(0)e^{-0.00012054733t}[/tex]

A scientist determined that the bones from a mastodon had lost 77.8 ​% of their​ carbon-14. How old were the bones at the time they were​ discovered?

Had 100 - 77.8 = 22.2% remaining, so this is t for which:

[tex]A(t) = 0.222A(0)[/tex]

Then

[tex]0.222A(0) = A(0)e^{-0.00012054733t}[/tex]

[tex]e^{-0.00012054733t} = 0.222[/tex]

[tex]\ln{e^{-0.00012054733t}} = \ln{0.222}[/tex]

[tex]-0.00012054733t = \ln{0.222}[/tex]

[tex]t = -\frac{\ln{0.222}}{0.00012054733}[/tex]

[tex]t = 12485[/tex]

The bones were 12,485 years old at the time they were​ discovered.

Express the confidence interval in the form of .

Answers

Answer:

0.075 - 0.022 < p < 0.075 + 0.022

Do not evaluate each of the math expressions above.

===========================================================

Explanation:

The given confidence interval is in the form (L, U)

L = lower bound = 0.053U = upper bound = 0.097

Find the midpoint of L and U to get

(L+U)/2 = (0.053+0.097)/2 = 0.075

This is the value of [tex]\hat{p}[/tex] which is the symbol p-hat or phat (both pronounced the same). It's the sample proportion.

To get the margin of error E, we could do either of the following

E = (U-L)/2 = (0.097-0.053)/2 = 0.022E = U - phat = 0.097 - 0.075 = 0.022E = phat - L = 0.075 - 0.053 = 0.022

This value of E represents half the width of the confidence interval. The full width being U-L.

The credit department of Lion's Department Store in Anaheim, California, reported that 30% of their sales are cash, 30% are paid with a credit card, and 40% with a debit card. Twenty percent of the cash purchases, 90% of the credit card purchases, and 60% of the debit card purchases are for more than $50. Ms. Tina Stevens just purchased a new dress that cost $120. What is the probability that she paid cash?

Answers

Answer:

Hence the probability that she paid cash is  0.105

Step-by-step explanation:  

P(cash) = 0.3  

P(credit card ) = 0.3  

P(debit card ) = 0.4  

P ( more than $50 | cash ) = 0.2  

P (more than $50 | credit card ) =0.9  

P (more than $ 50 |debit card ) = 0.6  

P ( more than $50) = P ( more than $50 | cash )* P (cash) + P (more than $50 credit card ) * P(credit card ) + P (more than $ 50 |debit card )* P(debit card )  

= 0.2 * 0.3 + 0.9 * 0.3 + 0.6* 0.4  

= 0.57  

P ( more than $50) = P ( more than $50 | cash )* P (cash) / P ( more than $50)  

= 0.2* 0.3 / 0.57  

= 0.105

Let u = (3, 4) and suppose v = (a, b) is a unit vector orthogonal to u. Then | b| equals:

Answers

Answer:

|b| = 3/5 = 0.6

Step-by-step explanation:

Two vectors

W = (w₁, w₂)

V = (v₁, v₂)

Are orthogonal if their dot product is equal to zero, this is:

W.V = 0 = w₁*v₁ + w₂*v₂

Here we know that:

u = (3, 4) and v = (a, b) are orthogonal.

And v is an unit vector, which means that:

II v II = 1 = √( a^2 + b^2)

or simply:

1 = a^2 + b^2

And because these vectors are orthogonal, we also have that:

3*a + 4*b = 0

Then we have two equations:

1 = a^2 + b^2

3*a + 4*b = 0

We want to find the value of |b|

For that, we can start by isolating a in the second equation, so we get:

3*a = -4*b

a = (-4/3)*b

Now we can replace that in the first equation to get:

1 = ((-4/3)*b)^2 + b^2

1 = (16/9)*b^2 + b^2

1 = (25/9)*b^2

1*(9/25) = b^2

(9/25) = b^2

Then we will have that:

|b| = √b^2 = √(9/25) = 3/5

|b| = 3/5 = 0.6

Answer:  negative integers greater than -10

This is because stuff on the number line to the right is larger than stuff on the left. We can say 2 < 7 since 7 is to the right of 2.

Also, -7 < -2 for similar reasoning.

Saying integers greater than -10 excludes this endpoint. We stop once we reach -1 because 0 and anything larger aren't negative integers.
