How can I write a story about the doubles plus 2 fact 5+7=12.??

aksik [14]

One <u>possible story</u> is:

I had 5 apples. My sister gave me 7, and now I have 12.

Explanation:

We are writing a story for 5+7=12. This means we need to start with 5 objects and somehow gain 7 more. In our story, we start with 5 apples and we get 7 more.

The last part is that our total must be 12. In our story, we end with 12 apples.

find two consecutive odd integers that 7 times the smaller integer is 61 more than 2 times the larger integer.

Aleks04 [339]

Answer:

x = 13 smaller integer

x + 2 = 15 the other integer

Step-by-step explanation:

x = the smaller integer

x + 2 = the next integer

7(x) = 61 + 2(x + 2)

7x = 61 + 2x +4

5x = 61 + 4

5x = 65

x = 13 smaller integer

x + 2 = 15 the other integer

An art history professor assigns letter grades on a test according to the following scheme.A: Top 5% of scoresB: Scores below th

adoni [48]

Answer:

Grade B score:

$76 \leq x \leq 89$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 73.3

Standard Deviation, σ = 9.7

We are given that the distribution of score on test is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

B: Scores below the top 5% and above the bottom 62%

We have to find the value of x such that the probability is 0.62

$P( X > x) = P( z > \displaystyle\frac{x - 73.3}{9.7})=0.62$

$= 1 -P( z \leq \displaystyle\frac{x - 73.3}{9.7})=0.62$

$=P( z \leq \displaystyle\frac{x - 73.3}{9.7})=0.38$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 73.3}{9.7} = 0.305\\\\x = 76.26$

We have to find the value of x such that the probability is 0.05

$P(X < 0.95) = \\\\P( X < x) = P( z < \displaystyle\frac{x - 73.3}{9.7})=0.95$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 73.3}{9.7} = 1.645\\\\x = 89.26$

Thus, the numerical value of score to achieve grade B is

$76 \leq x \leq 89$

I really need help with this ASAP

Alexandra [31]

Answer:

No. of boxes = 10

Oranges per box = 56

Total no. of oranges = 56*10=560

No. of bad oranges = 560/40= 14

(i) Probability of bad orange = 14/560 = 1/40

(ii) no of oranges expected to be bad = 14 ( found above)

Hope it helps.............. :)
