Graph f(x)=34x+2f(x)=34x+2.

1 answer:

4 0

If your equation is f(x) = 34x + 2, graph it like a normal linear equation.

Your slope (m) is 34 and your y-intercept (b) is 2.

So your line will cross the y-axis at y = 2 and then your slope will go up 34 over 1.

Let x be the amount of cement and y be the amount of sand. If the ratio of cement to sand for mortar is 1:3, then $\frac{x}{y} = \frac{1}{3}$ and y=3x.

So, if Sandy puts in x=7 shovels of cement, then she puts $y=3\cdot 7=21$ shovels of sand.

Answer: 21 shovels of sand.

Assume that the weight of two year old babies have distribution that is approximately normal with a mean of 29 pounds and a stan

Lana71 [14]

Answer:

25.15 ponds is the weight of two year old baby corresponds to 10th percentile.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 29 pounds

Standard Deviation, σ = 3 pounds

We are given that the distribution of weight of two year old babies is a bell shaped distribution that is a normal distribution.

Formula:

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

We have to find the value of x such that the probability is 0.10

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 29}{3})=0.10$

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

$P(z < -1.282) = 0.10$

$\displaystyle\dfrac{x - 29}{3} = -1.282\\x = 25.154 \approx 25.15$

Thus, 25.15 ponds is the weight of two year old baby corresponds to 10th percentile.

Step-by-step explanation:

Well if it's a greater than statement you can rule out C and D because those are less than symbols ( > = Less, < = Greater) It can't be A because thats his starting amount. The x means how many months it will take for him to get more than 70 stamps
