Can i get some help on these 2 im confused

Answer:

x = -12

Step-by-step explanation:

=> 1/2 (x-4) = -8

=> x-4 = -8 × 2

=> x-4 = -16

=> x = -16+4

=> x = -12

Answer:

2 * 10^-3 oz

Step-by-step explanation:

Given that:

Number of staples per box = 6 * 10^3

Weight of staple box = 12 oz

Weight per staple = (weight of staple box / number of staples per box)

Weight per staple = 12 / 6 * 10^3

Weight per staple = 12 / 6 * 1000

= 12 / 6000

= 0.002 oz

= 2 * 10^-3 oz

Answer:

0.80589

Step-by-step explanation:

So all of the numbers of correct answers less than 4 are 0,1,2,3

We need to calculate the probability for each separately and then add them together.

To find the probability we have to first find the combination. We know that there’s n=8 trials and that p=0.3. So 1-0.3 gives us 0.7.

The combination formula is: ! / (!(−)!)

So the n would always =8, and the r would be 0,1,2,3. So you would have to calculate it for 0,1,2,3 Separately. This can be done by hand or you can use a simple combinations calculator online.

For 0;

The combination is 1,

1 x 0.3^0 x 0.7^8-0 =

0.057648

For 1;

The combination is 8,

8 x 0.3^1 x 0.7^8-1 =

0.19765

For 2;

The combination is 28

28 x 0.3^2 x 0.7^8-2 =

0.296475

For 3;

The combination is 56

56 x 0.3^3 x 0.7^8-3 =

0.254122

All that’s left is to add these four numbers;

0.057647 + 0.19765 + 0.296475 + 0.254122 = 0.80589

Using the principle of binomial probability, the probability of correct answers fewer than 4 is : 0.8059

Recall the binomial probability formula :

P(x = x) = nCx * p^x * q^(n-x)

Where :

P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)

Using a binomial probability calculator :

Answer:

14cm

Step-by-step explanation:

Volume of the pyramid = Base area × height/3

V = BH/3

Base area = 14×width

Height= 9cm

Volume = 168cm³

Substitute into the formula

168 = 4w×9/3

36w = 168×3

36w = 504

w = 14cm

Hence the width of the pyramid is 14cm

Answer:

7.8^5

Step-by-step explanation:

Answer: 1. 3/8-1/4=1/8

2. 3/8+1/4=5/8

3. x=5/8

Step-by-step explanation: 1. you have to subtract 3/8 by 1/4 because you have to use the largest number to subtract for the smallest number so 3/8-1/4=1/8

2. Add by adding 3/8 by 1/4 because you have to find the value of x so 3/8+1/4=5/8

3. look at number 2. and the answer is x= 5/8

Answer:

x= -6

y= -5

Step-by-step explanation:

(x,y) = (-6, -5)

Answer:

(-6,-5)

x=-6

y=-5

Step-by-step explanation:

9x-7y=-19

5x-3y=-15

When solving with elimination, you multiply both equations by a number to get two terms to cancel each other out.

We can try to get the y's to cancel out. The LCD of 7 and 3 is 21, so we multiply one equation by 3 and another by -7 (to get one -21y and one 21y)

{9x-7y=-19}*3=

27x-21y=-57

{5x-3y=-15}*(-7)=

-35x+21y=105

Now, we combine the two equations.

27x-21y=-57

-35x+21y=105

-8x=48

Now, solve for x.

-8x=48

x=-6

Now we can plug x into one of the original equations to get y.

I will use 9x-7y=-19.

9(-6)-7y=-19

-54-7y=-19

Add 54 to both sides.

-7y=35

y=-5

We can put these values into an ordered pair: (-6,-5).

Answer:

34 degrees

Step-by-step explanation:

Before solving for g, we must remember that the inside of a triangle will always equal 180 degrees. Also, keep in mind that the little square at the top left corner of the triangle represents 90 degrees, so we can add both the existing degrees we know of:

90 + 56 = 146

And to find g, we simply subtract 180 by 146:

180 - 146 = 34

So, g is 34 degrees

Answer:

9.1%

Step-by-step explanation:

The price of a coffee has dropped to $2.50

Yesterday the price was $2.75

Therefore the percentage decrease can be calculated as follows

= 2.50 - 2.75/2.75 × 100

= -0.25/2.75 ×100

= 0.09090 × 100

= 9.1%

Hence the percentage decrease is 9.1%

Answer: 457.3

Step-by-step explanation:

[tex]V=\frac{lwh}{3}[/tex]

[tex]V=\frac{14*14*7}{3}[/tex]= 457.3

Answer:

V= 1568 in^3

Step-by-step explanation:

B = 14^2 = 196

896 = 14^2 + 2(14) (l)

896 = 196 + 28 (l)

700 = 281 l

25 = l

7^2 + b^2 = 25^2

49 = 625

24

1/3 (196)(24) = 1568

Answer:x=-7

Step-by-step explanation:

Answer:

In this problem you have to get rid of the 13 so you take the opposite of the number which is -13 and subtract it by 13 and when you do this you have to do the same thing on the other side so you would do 48-13 and that would give you get 35 so -5x=35. This is not the same because on B it says positive 5x, and on A it is negative 5x.

Answer:

Horizontal Asymptote → y = 17

Step-by-step explanation:

Given function is f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

Here, the parent function is g(x) = [tex]\frac{2}{5}(16)^x[/tex]

Parent function has a horizontal asymptote as y = 0

If the function g(x) is shifted 13 units left and 17 units up, new function will be f(x) = [tex]\frac{2}{5}(16)^{x+13}+17[/tex]

When the parent function is shifted 17 units up, horizontal asymptote shifts 17 units upwards.

Therefore, horizontal asymptote of the image function becomes y = 17.
