Answer:

Step-by-step explanation:

ΔABC & ΔADE are similar triangles

\frac{AD}{AB}=\frac{DE}{BC}\\\\\frac{12}{4}=\frac{12}{x}\\

Cross multiply,

12*x = 12*4

x=12*\frac{4}{12}\\

x = 1 * 4

x = 4

adelina 88 [10]

Answer:

81% of the balls are red

Step-by-step explanation:

If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball

18 red + 4 blue = 22 balls  part (a)

18/22 = 9/11   part (b) simplify

9/11 * 100     part (c) multiply the fraction by a hundred to get the percentage

To determine the effect of 100% nitrate on the growth of pea plants, several specimens were planted and then watered with 100% n
Bond [772]

Answer:

Step-by-step explanation:

From the attached photo

mean = 15.76

Standard deviation = 1.66

c) We want to determine a 90% confidence interval for the mean growth of pea plants

For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

It becomes

15.76 ± 1.645 × 1.66/√7

= 15.76 ± 1.645 × 0.63

= 15.76 ± 1.04

The lower end of the confidence interval is 15.76 - 1.04 =14.72

The upper end of the confidence interval is 15.76 + 1.04 =16.8

234% as a simplifed fraction
blagie [28]

Answer:

So, /(100÷2) = 117/50 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 234/100 is also equal to 2 17/50 when expressed as a mixed number.

Step-by-step explanation:
