3 0

Answer:

0.5

Step-by-step explanation:

  • Let h = weight of 1 hex bolt
  • Let a = weight of an one anchor bolt

1)  (12h + 10a = 7) × 3  ⇒ (1) 36h + 30a = 21

2)  (5h + 15 = 4) × -2 ⇒ + (2)  - 10h - 30a = 8

                                             ----------------------

                                                 26h  =   13

                                                 -----         -----

                                                  26          26

                                                 

                                          h = 13    ÷ 13

                                                  ---

                                                 26  ÷  13

                               

                                          h = 1

                                              ----          =  0.5

                                                 2

Let f(x) be an exponential functionWhich transformations to the graph of f(x) would describe e - f(x - 3) ?
gayaneshka [121]

Look at the graph below carefully

Observe the results of shifting ={2}^{x}f(x)=2​x

​​  vertically:

The domain, (−∞,∞) remains unchanged.

When the function is shifted up 3 units to ={2}^{x}+3g(x)=2​x +3:

The y-intercept shifts up 3 units to (0,4).

The asymptote shifts up 3 units to y=3y=3.

The range becomes (3,∞).

When the function is shifted down 3 units to ={2}^{x}-3h(x)=2 ​x​​ −3:

The y-intercept shifts down 3 units to (0,−2).

The asymptote also shifts down 3 units to y=-3y=−3.

The range becomes (−3,∞).

What is the number if 50% of 25% of a number is 48?
dedylja [7]

Answer:

384

Step-by-step explanation:

If 48 is 50% of something, that means

48 + 48 = 96. Now, what number is 96 25% of? well 96 • 4 = 384. Now let's do the math backwards!

25 % of 384 is 96. 50 % of 96 is 48! so your answer is 384! Hope this helps!!!

A container holds 50 electronic components, of which 10 are defective.
Gala2k [10]

Answer:

There is some inforrmation that is missing in this question. It should read:

A container holds 50 electronic components, of which 10 are defective. If 6 components are drawn at random from the container, the probability that at least 4 are not defective is . If 8 components are drawn at random from the container, the probability that exactly 3 of them are defective is .

Answers

Part 1.   0.02

Part 2.  0.0375

Explanation

The probability is a chance of an event happening. It is calculated as;

probability = (Number of favourable outcome)/(Number of available outcome)

Part 1

6 are chosen at random. If 4 are not defective, then 2 are defective.

P(at least 4 are not defective) = 4/40 × 2/10

                                               = 1/10 ×1/5

                                               = 1/50

                                                = 0.02

Part 2

8 are chosen at random. If 3 are defective, the 5 are not defective.  

P(3 are defective) = 3/40 × 5/10  

                            = 15/400

                            = 3/80

                           = 0.0375

Ali bought 2.152.15 pounds of turkey at $7.89$7.89 per pound, and 1.871.87 pounds of lamb at $7.89$7.89 per pound. Which express
Stella [2.4K]
In order to calculate the total cost of the purchase, we must first assess that there were two items bought, turkey and lamb. Next, we see multiply the cost of the first item by its quantity, so:
cost(T) = 2.15 * 7.89
cost(T) = $16.96
And repeat for the second item:
cost(L) = 1.87 * 7.89
cost (L) = $14.75

Finally, the total cost is the sum of these costs. So
Total = 16.96 + 14.75
Total = $31.71
