Answer:

Step-by-step explanation:

(4, -6) and (-5, 9)

Slope is m

m = (y2 - y1)/(x2 - x1)

y2 = 9, y1 = -6, x2 = -5 and x1 = 4

m = {9-(-6)}/{-5 -4}

m = {9+6}/(-9)

m = 15/-9

m = -5/3

Answer:

-5/3

Step-by-step explanation:

gradient/m = y1 - y2/ x1 - x2

so, 9-(-6)/ -5-4

= 15/-9 , which simplifies to -5/3 If divided both numbers by 3

Which graph represents a quadratic function that has no real zeros?
xxTIMURxx [149]

Answer:

2nd graph (in the attached pics)

Step-by-step explanation:

Graphically, the <em>x-intercepts of the graph of a quadratic function are its zeroes. </em>

There can be

  • no zeroes (where graph doesn't cut the x-axis at all),
  • 1 zero (where graph touches the x-axis at one point only), and
  • 2 zeros (where the graph cuts the x-axis at 2 points)

Looking at the figures, the 2nd graph has no real zeroes, <em>because the graph doesn't cut the x-axis at all!</em>

<em />

So, the answer is the second graph.

Three landmarks of baseballachievement are Ty Cobb’s batting average of 0.420 in 1911,Ted Williams’s 0.406 in 1941, and George B
harina [27]

Answer:

Ted Williams has the highest standardized score, hence Williams is the best of the three

Cobb is the second highest and hence, the better player

George Brett is third

Step-by-step explanation:

Given the data:

Decade : 1910 __ 1940 ____ 1970

Mean, μ: 0.266 __0.267 ___ 0.261

S/dev, σ : 0.0371 _ 0.0326 __ 0.0317

To compute the standard unit for batting averages, we obtain the standardized score for each of Cobb,Williams, and Brett.

Standardized score (Zscore) : (x - μ) / σ

Cobb, x = 0.420

Ted Williams, x = 0.406

George Brett, x = 0.390

COBB:

Zscore = (0.420 - 0.266) / 0.0371 = 4.1509

Ted Williams :

Zscore = (0.406 - 0.267) / 0.0326 = 4.2638

George, Brett = (0.390 - 0.261) / 0.0317 = 4.0694

Ted Williams has the highest standardized score, hence Williams is the best of the three

Cobb is the second highest and hence, the better player

George Brett is third

Ricardo spends 8/9 hr. reading the paper. He spends 1/4 of the time reading world news and splits the remaining time equally bet
lapo4ka [179]
Total time spent reading is = 8/9 hour

He spends 1/4 of the time reading world news. That is =  1/4 * 8/9 =  2/9 hour

Splits the remaining time equally.  Remaining time =  8/9 - 2/9 =  6/9

Splitting it equally =  6/9  divided by 2 =  6/9  * 1/2 =  3/9  = 1/3

Time spent reading comic is = 1/3 hour

I hope this helps.

How do you simplify, if possible, 3pq x 5qp?
pav-90 [236]
15p^2q^2 because you multiply the coefficients and the vaiables. 3x5 is 15, pxp is p^2, and qxq is q^2
