Answer:

a. Strawberry > Rasberry

6.18 > 6.1

b. required more in strawberry

Step-by-step explanation:

Given that

Strawberry = 6.18 pound

Raspberry = 6.1 pound

Based on the above information

As we can see that the number of pounds in strawberry is more than the number of pounds in Rasberry

So, it would be

a. Strawberry > Rasberry

6.18 > 6.1

b.  Here the inequality means that the number of pounds is required more in Strawberry as compared to the Rasberry so that the jam could be made

If you were to flip a coin 10 times, what is the probability that it will land on heads exactly 7 out of 10 times?
bezimeni [28]

Answer:

The probability of flipping a coin 10 times and it landing on heads exactly seven times is about 0.1172 or 11.72%.

Step-by-step explanation:

We can use basic binomial distribution, which is given by the formula:

\displaystyle P(x) = {n \choose x}p^xq^{n-x}

Where <em>n</em> represent the number of trials, <em>x</em> represent the number of successes desired, <em>p</em> represent the chance of success, and <em>q</em> represent the chance of failure.

Since we are flipping a coin 10 times, we are conducting 10 trials. So, <em>n</em> = 10.

We want to probability that it lands on heads exactly 7 out of 10 times. So, the number of desired successes <em>x</em> is 7.

The probability of success <em>p</em> is 1/2.

And the probability of failure <em>q</em> is also 1/2.

Substituting:

\displaystyle P(7)={10 \choose 7}\left(\frac{1}{2}\right)^7\left(\frac{1}{2}\right)^3=120\left(\frac{1}{2}\right)^{10}=\frac{120}{1024}=\frac{15}{128}\approx0.1172

The probability of flipping a coin 10 times and it landing on heads exactly seven times is about 0.1172 or 11.72%.

Chanelle deposits $7,500 into the bank. She does not withdraw or deposit money for 6 years. She earns 6% interest during that ti
koban [17]

Answer: a. $2700

b. $10200

Step-by-step explanation:

a. The interest she would have earned at the end of the 6 years can be gotten using the formula

= PRT/100

= $7500 × 6% × 6

= $7500 × 6/100 × 6

= $7500 × 0.06 × 6

= $2700

b. Her balance when she wants to withdraw the money would be:

= $7500 + $2700

= $10200

Which equation represents a line that passes through the two points in the
lesya [120]

Answer: The slope is 2/3, y=2/3x+1

Step-by-step explanation: The 2 points, (3,3) and (6,5), use the method y2-y/x2-x1. Then you find the slope that way, then use point slope form for the slope intercept form: y-y1=m(x-x1), then substitute and solve to get y=2/3x+1
