#a

H(0)

It refers to y value on graph when x is 0

So here it refers to y intercept

  • y intercept (0,5)

Hence

  • H(0)=5

#b

Observe the graph

y intercept is not 0 so it's not true

#3

Domain is set of x values in graph

  • [0,oo)

#4

Range is set of y values on graph

  • [5,50]

6. CAN SOMEONE PLEASE HELP ME? I'M NOT GOOD IN MATH.<br>Explain your work please​
melomori [17]

Answer:

6√2

Step-by-step explanation:

This is a right triangle. The legs of a right triangle are the sides that make up the right angle, and the hypotenuse is the side opposite to the right angle. To find x, we will use the Pythagorean Theorem. This states that a² + b² = c², where a and b are the legs and c is the hypotenuse. Since we know that the legs are both x and the hypotenuse is 12, we can plug these values into our equation to get  x² + x² = 12².

2x²=144 → x² = 72 → x = √72, which simplifies to x = 6√2. Hope this made sense and helps!

Babies born after a gestation period of 32-35 weeks have a mean weight of 2700 grams and a standard deviation of 700 grams, whil
Nutka1998 [239]

Answer:

The 33 week gestation period baby has the higher z-score, so he weighs more relative to other babies of the same gestation period.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Who weighs more relative to other babies of the same gestation period?

Whoever has the higer z-score

33 - week baby.

Babies born after a gestation period of 32-35 weeks have a mean weight of 2700 grams and a standard deviation of 700 grams. A 33-week gestation baby weighs 2950 grams.

We have to find z when \mu = 2700, \sigma = 700, X = 2950. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{2950 - 2700}{700}

Z = 0.357

40-week baby

Mean weight of 3000 grams and a standard deviation of 490 grams. 40-week gestation baby weighs 3150 grams.

We have to find Z when \mu = 3000, \sigma = 490, X = 3150. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{3150 - 300}{490}

Z = 0.306

The 33 week gestation period baby has the higher z-score, so he weighs more relative to other babies of the same gestation period.

4x - 5y = -28<br>-3x - 2y = 10​
kozerog [31]

Answer:

y=-4/23

im not sure i didn't check (might be wrong)

Step-by-step explanation:

4x - 5y = -28

-3x - 2y = 10​

then make x the same

So

12x-15y=-84

-12x-8y=80

then its left with

-23y=-4

y=-4/23

find x by entering y into -3x - 2y = 10 and solving
