Answer: 0.9844

Step-by-step explanation:

given data:

sample size n = 6

It’s assumed that half the population are male and the remaining half are females

F = 1/2

M = 1/2

the probability that the investigator would draw altleats one male

P ( x ≥ 1 ) =

= 1 - ( 0.5 ) ^ 6

= ( 0.5 )^6

= 0.9844

Scorpion4ik [409]

Answer:

(x + 8)

Step-by-step explanation:

If you factor x2 + 5x – 24 using the AC method, it equals (x - 3) and (x + 8).

St. Augustine grass can grow at the rate of 4 over 7 centimeter per week.
kotegsom [21]

Given, the rate of growth of St. Augustine grass is \frac{4}{7} cm per week.

We have to find the number of weeks that the grass grow to \frac{12}{7} cm.

Let's take the number of weeks be x.

In 1 week the grass grow = \frac{4}{7} cm

So in x weeks the grass grow = (\frac{4}{7}) (x) =\frac{4x}{7} cm

So we can write,

\frac{4x}{7} =\frac{12}{7}

To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,

(\frac{4x}{7}) (7) =(\frac{12}{7})(7)

4x =(\frac{12}{7})(7)

4x = 12

Now to get we will move 4 to the right side by dividing it to both sides. We will get,

\frac{4x}{4} =\frac{12}{4}

x = 3

So we have got the required answer.

After 3 weeks the grass grow \frac{12}{7} cm.

9. A recent study examining the effects of sugar consumption on a middle
ExtremeBDS [4]

Answer:

(B) Because the confidence interval includes 0, we don't have convincing evidence that sugar causes faster reading times, on average.

Step-by-step explanation:

Confidence Interval for the population mean difference in reading is basically an interval of range of values where the true population mean difference in reading time can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample mean) ± (Margin of error)

In using confidence interval of population mean difference in reading times for hypothesis testing, if the interval obtained contains a value of 0, it means the population mean difference in reading times can take on a value of 0 and indicate that there isn't enough evidence to conclude that there is a significant difference in the two quantities being compared. (The null hypothesis is true).

If the interval doesn't contain a 0, then it can be concluded that there is enough evidence to conclude that there is significant difference in the two quantities being compared.

Hope this Helps!!!

Which cross-sectional shape do you find the most surprising? Which shape do you find the least surprising ? Explain why
natita [175]

Answer:

The circles were the least surprising because the base of the cone is a circle. The curves that look like bent rods were the most surprising, because I have not seen geometric figures like those before.
