Let's start with what we know, 3/5 pounds is equal to 60% or 0.60. 0.60÷6=0.10 pounds of sugar daily. So, Mrs. Campbell used one tenth of a pound. (1/10 or 0.10 or 0.1) I hope this helps!

Answer:

.10 pounds of sugar each day.

Step-by-step explanation:

In order to solve this we first have to calculate how many pounds of sugar she used in total, we just need to solve the fraction 3/5

3/5=.60

So she used .6 pounds in the 6 days, if she used the same amount each day, we just divide the .6 by the 6 days:

.6/6=.1 pounds

So we know that Mrs Campbell used .1 pounds a day.

Find the exact value of csc ø, if cos ø= 1/9; 180° less ø less than 270°
Iteru [2.4K]

Answer:

The answer to your question is: the first option  - 9/ \sqrt{80}

Step-by-step explanation:

Process

          cosФ = adjacent side / hypotenuse

          -1/9 = adjacent side / hypotenuse

          adjacent side = -1    hypotenuse = 9

          c² = a² + b²

          b² = c² - a²

           b² = 81 - 1

           b = \sqrt{80} \\    b = opposite side

But b is negative because we are in the third quadrant.

          b = -\sqrt{80}

Finally   csc Ф = hypotenuse / opposite side

             csc Ф = - 9 / \sqrt{80}

Roll a die 10 sided die 3 times. What is the probability that the sequence is strictly increasing or decreasing?
snow_lady [41]

Answer:

The probability of obtaining a sequence which is neither strictly increasing nor decreasing in 0.76.

Step-by-step explanation:

We have 10 possible outcomes on a single throw.

So, outcomes in 3 throws = 10^{3} =1000 outcomes.

Let x be the number of strictly increasing arrangements.

Let y be the number of strictly decreasing arrangements.

Let z be the number of outcomes that are neither strictly decreasing nor strictly increasing

So, we have x+y+z=1000

If we look at a strictly increasing arrangement from the other/opposite side, it will look like a strictly decreasing arrangement.

So, x = y

Hence, we can say the final equation will be :

2x+z=1000

And for strictly increasing arrangements ,all 3 numbers will be different and it can be done in 10C3 ways.

10C3=\frac{10!}{3!7!} = 120 ways

So, 2x=2\times120=240

Thus z=1000-240=760

So, the probability is = \frac{760}{1000} = 0.76

Therefore, the probability of obtaining a sequence which is neither strictly increasing nor decreasing in 0.76.

Evaluate using suitable identity:<br>e). 102 × 98​
chubhunter [2.5K]

Step-by-step explanation:

<h3><u>★ Solution :-</u></h3>

\sf \longmapsto 102 \times 98

\sf \longmapsto (a + b)(a - b) = a^2 - b^2

Here,

  • a = 100
  • b = 2

\sf \longmapsto (100 + 2)(100 - 2) = 100^2 - 2^2

\sf \longmapsto 100^2 - 2^2

\sf \longmapsto 10000 - 4

\sf \longmapsto 9996
