Answer:

The equation is x + 17 > 26

x > 9

Step-by-step explanation:

The sum of a number and 17 is no less than 26

Let "x" be a number.

The sum of a number and 17 = x + 17

No less than means ">"

So, the inequality is x + 17 > 26

We can solve this inequality.

Solve for x.

Subtract 17 on both sides, we get

x + 17 - 17 > 26 - 17

x > 9

We put this into an algebraic equation, where x = the number .
x + 17 > 26
x > 9

This > is the greater than sign, we use this because it's no less than 26.
Ideally we would use this sign:

because it could be equal to 26.

The number is greater or equal to 9

Solve the following inequality for d. Write your answer in simplest form.

suter [353]

Answer:

d>67

Step-by-step explanation:

Let's solve your inequality step-by-step.

−50−(−9d+7)>−d+10+9d

Step 1: Simplify both sides of the inequality.

9d−57>8d+10

Step 2: Subtract 8d from both sides.

9d−57−8d>8d+10−8d

d−57>10

Step 3: Add 57 to both sides.

d−57+57>10+57

d>67

Which equation could define the function below?

dimulka [17.4K]

Answer:

y= (x+1)(x+ .5) (x+ 3.5)

y= (x+1) (X - .5) (x-3.5)

y = (x-1) (X-.5) (x-3.5)

y= (x+1) (X- .5) (x +3.5)

Siri is grocery shopping. She is buying macaroni. One box is 6 inches long, 1 inch wide and 9

sashaice [31]

Answer:

The second box

Step-by-step explanation:

The volume of a pyramid can be given by the formula: V=31Ah. Where. A: Area of the V=(1/3)(B)(h)

multiply both sides by 3

3V=Bh

divide both sides by B

3V/B=h

Therefore, If it is wider it has more space to carry more items such as macaroni.

I hope this helps! (:

According to the manufacturer of the candy Skittles, 20% of the candy produced are red. If we take a random sample of 100 bags o

Answer:

Probability that the proportion in our sample of red candies will be less than 20% is 0.5 .

Step-by-step explanation:

We are given that 20% of the candy produced are red. A random sample of 100 bags of Skittles is taken.

The distribution we can use here is;

$\frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } }$ ~ N(0,1)

where, p = 0.20 and n = 100

Let $\hat p$ = proportion of red candies in our sample

So, P( $\hat p$ < 0.20) = P( $\frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } }$ < $\frac{0.20 - 0.20}{\sqrt{\frac{0.2 (1- 0.2)}{100} } }$ ) = P(Z < 0) = 0.5
