The measure of <ABC is 90 degrees and the measure of <DBC is 33 degrees

How would you show a rate of change of 3.5 meters per minute on a graph name some of the points

-30 + 5a < 16 A. a 9.2 C. a < 9.2 a> -2.8 a < -2.8

Goryan [66]

Answer:

-30 + 5a < 16

5a < 46

$a < \frac{46}{5}$

a < 9.2

Hope this help...

( what’s the better deal ) please help me with this, i’ve been trying for a long time

ValentinkaMS [17]

Answer:

Brand A is the better deal!

Step-by-step explanation:

Let's start by comparing.

We know brand B has the following cost: 5 ounces = $3.75

10 ounces $7.50 and 16 ounces = $12

Now check the graph.

6 ounces cost $3

12 ounces cost $6

20 ounces cost $10

I don't think we need to look any further but brand A is the better deal!

Question 1: The answer is D. which it ended up being 0.9979

Question 2: The expression P(z > -0.87) represents the area under the standard normal curve above a given value of z. What is P(z > -0.87)? Express your answer as a decimal to the nearest ten thousand

The expression P(z > -0.87) represents the area under the standard normal curve above a given value of z. What is P(z > -0.87)? Express your answer as a decimal to the nearest ten thousandth (four decimal places). So being that rounding it off would mean your answer would be = ?

Question 3: Assume that the test scores from a college admissions test are normally distributed, with a mean of 450 and a standard deviation of 100.
a. What percentage of the people taking the test score between 400 and 500?
b. Suppose someone receives a score of 630. What percentage of the people taking the test score better? What percentage score worse?
c. A university will not admit a student who does not score in the upper 25% of those taking the test regardless of other criteria. What score is necessary to be considered for admission? z = 600-450 /100 = .5 NORMSDIST(0.5) = .691462 z = 400-450 /100 = -.5 NORMSDIST(-0.5) = .30854

P( -.5 < z <.5) = .691462 - .30854 = .3829 Or 38.29%
Receiving score of 630:
z = 630-450 /100 = 1.8 NORMSDIST(1.8) = .9641
96.41% score less and 3.59 % score better
upper 25%
z = NORMSINV(0.75)= .6745
.6745 *100 + 450 = 517 Would need score >517 to be considered for admissions 
Question 4: The z-score for 45cm is found as follows:
Reference to a normal distribution table, gives the cumulative probability as 0.0099.
Therefore about 1% of newborn girls will be 45cm or shorter.

PLEASE HELP!! this is due really soon

Answer: There are 467 students at Holmes Junior High.

There are 342 students at Harper Junior High.

_________________________________________________

Step-by-step explanation:

_________________________________________________

Let " x" represent the number of students at Harper Jr. High.

Holmes Junior has: " (x + 125) " students .

Harper Junior High has: " x" students:

_________________________________________________

Together, the total number of students equal: " 809 " students.

so: " x + (x + 125) = 809 " .

We want to solve for "x" and " (x + 125)" .

We want to solve for "x" ;

then we can solve for " (x + 125) " by adding "125" ;

to our "solved value for "x" ;

____________________________________________

x + (x + 125) = 809 .

→ 1x + 1x + 125 = 809 ;

→ 2x + 125 = 809 ;

Now, subtract "125" from each side of the equation:

→ 2x + 125 - 125 = 809 - 125 ;

→ 2x = 684 ;

Now, divide each side of the equation by "2" ;

to isolate: "x" on one side of the equation; & to solve for "x" ;

→ 2x/ 2 = 684 / 2 ;

to get:

→ x = 342 ; which is the total number of students at Harper Jr. High.

Now, to solve for: " (x + 125)" ;

Plug in: "342" for "x" ;

→ " (342 + 125) " = " 467 " '

→ which is the total number of students at Holmes Jr. High.

_________________________________________________

Do our answers make sense:

Does: " 342 + 467 =? 809 ?? " ;

→ Yes!

_________________________________________________

Answer: There are 467 students at Holmes Junior High.

There are 342 students at Harper Junior High.
