Answer:

The number of bagels is 11 and the cups of coffee is 12.

Step-by-step explanation:

Given:

Keisha bought cups of coffee and bagels for the people in her office. Each bagel cost $2 and each cup of coffee cost $1.50.

Keisha spent a total of $40 to buy 23 items.

Now, to find the number of cups of bagels and coffee.

As given in question:

Let $x$ represent the number of bagels.

And $y$ represent the number of cups of coffee.

So, the total number of items:

$x+y=23$

$x=23-y$ ......(1)

Now, the total money spent on items:

$2x+1.50y=40$

Substituting the value of $x$ from equation (1):

$2(23-y)+1.50y=40$

$46-2y+1.50y=40$

$46-0.50y=40$

Subtracting both sides by 46 we get:

$-0.50y=-6$

Dividing both sides by -0.50 we get:

$y=12.$

The number of cups of coffee = 12.

Now, to get the number of bagel we substitute the value of $y$ in equation (1):

$x=23-y$

$x=23-12$

$x=11.$

The number of bagels = 11.

Therefore, the number of bagels is 11 and the cups of coffee is 12.

Explain when each method(graphing, substitution,linear combinations) is a good method to find a solution to a system of equation

PSYCHO15rus [73]

Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.

Jim Tree sells trees. The mean length of the trees purchased was 68 inches with a standard deviation of 10 inches. Jim wants to

Zepler [3.9K]

Step-by-step explanation:

We know that,

$Z=\dfrac{X-\mu}{\sigma}$

Where,

X = raw score = 84

μ = mean = 68

σ = standard deviation = 10

Putting the values,

$Z=\dfrac{84-68}{10}=1.6$

The percent of his sales that were less than or equal to 84 inches, is

$P(Z\leq 1.6)=0.9452=94.52\%\approx 94.5\%$

Therefore, the remaining 100-94.5=5.5% were more than 84 inches.
