Answer:

The System of equation representing number of each plant bought is  \left \{ {{x+y=24} \atop {3.20x+1.50y =49.6}} \right..

Step-by-step explanation:

Given:

Total number of plants bought = 24

The plants you have picked out are blooming annuals and non-blooming annuals.

Let the Number of blooming annuals plants be 'x'.

Also Let the Number of non-blooming annuals plants be 'y'.

So we can say that;

Total number of plants bought is equal to sum of the Number of blooming annuals plants and the Number of non-blooming annuals plants.

framing in equation form we get;

x+y=24 \ \ \ \ equation \ 1

Also Given:

Cost of blooming annuals = $3.20

Cost of non-blooming annuals = $1.50

Total Cost of Plants which were bought = $49.6

Now we know that;

Total cost of plants which were bought is equal to sum of the Number of blooming annuals plants multiplied by Cost of blooming annuals and the Number of non-blooming annuals plants multiplied by Cost of non-blooming annuals.

framing in equation form we get;

3.20x+1.50y =49.6 \ \ \ \ equation\ 2

Hence the System of equation representing number of each plant bought is  \left \{ {{x+y=24} \atop {3.20x+1.50y =49.6}} \right..

Of a group of randomly selected adults, 360 identified themselves as manual laborers, 280 identified themselves as non-manual wa
Wittaler [7]

Answer:

We are 95% confident that the percent of executives who prefer trucks is between 19.43% and 33.06%

Step-by-step explanation:

We are given that in a group of randomly selected adults, 160 identified themselves as executives.

n = 160

Also we are given that 42 of executives preferred trucks.

So the proportion of executives who prefer trucks is given by

p = 42/160

p = 0.2625

We are asked to find the 95% confidence interval for the percent of executives who prefer trucks.

We can use normal distribution for this problem if the following conditions are satisfied.

n×p ≥ 10

160×0.2625 ≥ 10

42 ≥ 10 (satisfied)

n×(1 - p) ≥ 10

160×(1 - 0.2625) ≥ 10

118 ≥ 10 (satisfied)

The required confidence interval is given by

$ p \pm z\times \sqrt{\frac{p(1-p)}{n} } $

Where p is the proportion of executives who prefer trucks, n is the number of executives and z is the z-score corresponding to the confidence level of 95%.

Form the z-table, the z-score corresponding to the confidence level of 95% is 1.96

$ p \pm z\times \sqrt{\frac{p(1-p)}{n} } $

$ 0.2625 \pm 1.96\times \sqrt{\frac{0.2625(1-0.2625)}{160} } $

$ 0.2625 \pm 1.96\times 0.03478 $

$ 0.2625 \pm 0.06816 $

0.2625 - 0.06816, \: 0.2625 + 0.06816

(0.1943, \: 0.3306)

(19.43\%, \: 33.06\%)

Therefore, we are 95% confident that the percent of executives who prefer trucks is between 19.43% and 33.06%

Which equation is an identity?​
kirza4 [7]

Answer:

Option (3).

Step-by-step explanation:

Option (1).

3(x - 1) = x + 2(x + 1) + 1

3x - 3 = x + 2x + 2 + 1

3x - 3 = 3x + 3 [Not True]

Therefore, this equation is not an identity.

Option (2).

x - 4(x + 1) = -3(x + 1) + 1

x - 4x - 4 = -3x - 3 + 1

-3x - 4 = -3x - 2 [Not true]

Therefore, this equation is not an identity.

Option (3).

2x + 3 = \frac{1}{2}(4x + 2) + 2

2x + 3 = 2x + 1 + 2

2x + 3 = 2x + 3 [True]

Therefore, this equation is an identity.

Option (4).

\frac{1}{2}(6x-3)=3(x+1)-x-2

3x - 1.5 = 3x + 3 - x - 2

3x - 1.5 = 2x + 1 [Not true]

Therefore, this equation is not an identity.

Write an expression for the sequence of operations described below.
Lemur [1.5K]
This might look hard at first, but if you break it down into parts, it will be much easier. With that said, start with what you know. You see that the word problem says "the difference of y and 9", which means that you have to stubtract them. So, part of the equation is going to be y - 9. Now to look at the rest of the word problem. It says to divide by 3, so now you have to take what you have so far and divide that by 3. This means that you are going to have to divide the y - 9 by 3. 

Your answer should be:
y - 9 / 3

***** Note: The slash means division. *************************************
