Given : In preparation for a party, brant is putting desserts onto platters. the chocolate cake is cut into 15 pieces and the cheesecake is cut into 6 pieces. if he wants to prepare identical platters without having any cake left over.

To find : What is the greatest number of platters he can prepare?

Solution :

The greatest number of platters he can prepare is given by finding the GCF of 15 and 6.

Factoring the numbers,

6=2\times 3

15=3\times 5

The GCF is the greatest common factor.

GCF(6,15)=3

Therefore, the greatest number of platters he can prepare is 3.

What is the slope of the line?
Ede4ka [16]

Answer:

-1

Step-by-step explanation:

Remember, slope is rise/run

Start from a point on the line and count up and over until you reach another point on the line.

For example, start from (0,-2), count up and left until you get to (-2,0). This gets you 2/2, which reduces to 1.

Since the line represents a negative slope, the slope is -1.

Sarina throws a ball up into the air, and it falls on the ground nearby. The ball's
Anuta_ua [19.1K]

Answer:

Option C.

Step-by-step explanation:

It is given that the ball's height, in feet, is modeled by the function

f(x)=-x^2-x+3

where, x represents time in seconds.

We need to find the height of the ball when Sarina throws it. It means, we need to find the initial height of the ball.

Substitute x=0 in the given function, to find the initial height.

f(0)=-(0)^2-(0)+3

f(0)=0+0+3

f(0)=3

The height of the ball is 3 feet when Sarina throws it.

Therefore, the correct option is C.

Sergeu [11.5K]

Answer:

Check the explanation

Step-by-step explanation:

Below are the null and alternative Hypothesis,

Null Hypothesis, H0: μ = 300000

Alternative Hypothesis, Ha: μ < 300000

Test statistic,

z = (xbar - mu)/(sigma/sqrt(n))

z = (288000 - 300000)/(80000/sqrt(25))

z = -0.75

P-value Approach

P-value = 0.2266

As P-value >= 0.05, fail to reject null hypothesis.
