Answer: \frac{8}{25}

Step-by-step explanation:

The total number of cards in the bag=16+16+18=50

The number of cards has triangle = 16

The probability that a randomly selected card has a triangle drawn on it is given by :-

=\frac{\text{Number of cards has triangle}}{\text{Total cards}}\\\\=\frac{16}{50}\\\\=\frac{8}{25}

Hence, the probability that a randomly selected card has a triangle drawn on it =\frac{8}{25}

Lelu [443]

Answer:

See picture.

Step-by-step explanation:

This line is in point slope form y - y_1 = m(x-x_1) where (x_1, y_1) is a point on the line. Begin graphing the line by first graphing the point (-3, 3) from the equation. Then move up 1 unit and over 2 units according to slope. This new point is (-1,4).

The authors of a paper presented a correlation analysis to investigate the relationship between maximal lactate level x and musc
ArbitrLikvidat [17]

Answer:

a) Sample correlation coefficient, r = 0.7411

bi) test statistic, t = 4.102

bii) P-value = 0.000736

Step-by-step explanation:

a) The formula for the sample correlation coefficient is given by the formula:

r = \frac{S_{xy} }{\sqrt{S_{xx} S_{yy} }} }

S_{xx} = 2,648,130.357\\S_{yy} = 36.7376,\\S_{xy} = 7408.225

r = \frac{7408.225}{\sqrt{2648130.357*36.7376} }

r = 0.7511

b)

i) formula for the test statistic is given by the formula:

t = \frac{r\sqrt{n-1} }{\sqrt{1 - r^{2} } }

sample size, n = 4

t = \frac{0.7511\sqrt{14-1} }{\sqrt{1 - 0.7511^{2} } }

t = 4.102

ii) Degree of freedom, df = n -2

df = 14 -2

df = 12

The P-value is calculate from the degree of freedom and the test statistic using excel

P-value =(=TDIST(t,df,tail))

P-value = (=TDIST(4.1,12,1)

P-value = 0.000736
