Help me please ASAP

Mathematics
1 answer:
Lina20 [59]3 years ago
7 0

Answer:

m<2 = 70degrees

m<3 = 70degrees

m<4 = 110degrees

m<5 = 110degrees

m<6 = 70degrees

m<7 = 70degrees

m<8 = 110degrees

Step-by-step explanation:

A line has the angles of 180 degrees so if m<1 is 110 then m<2 must be 70degrees. Then m<4 is opposite side of m<1 so it has to be the same number of degrees and the same for m<3 is the opposite side of m<2.

Automatic banking machine (ABM) customers can perform a number of transactions quickly and efficiently. A banking consultant has
garri49 [273]

Answer:

77.34% of ABM customers take more than 31 seconds to do their banking.

Step-by-step explanation:

Problems of normally distributed samples are 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.

In this problem, we have that:

\mu = 34, \sigma = 4

What percentage of ABM customers take more than 31 seconds to do their banking?

This is 1 subtracted by the pvalue of Z when X = 31.

So

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

Z = \frac{31 - 34}{4}

Z = -0.75

Z = -0.75 has a pvalue of 0.2266.

So 1-0.2266 = 0.7734 = 77.34% of ABM customers take more than 31 seconds to do their banking.

In ΔABC, ∠A = 50° and the external bisectors of ∠B and ∠C meet at O as shown in figure. The measure of ∠BOC is
FromTheMoon [43]

Answer:

17

Step-by-step explanation:

Look at Triangle ABC, The rays meet at line BC and they are both from the interior point A. So this means that AB=AC. This makes ABC a isosceles triangle. Using the isosceles triangle theorem, Angle B and Angle C measure is equal to each other so

50 + x + x = 180

50 + 2x = 180

2x = 130

x = 65

This means angle b and C of the triangle ABC measure is 65.

External bisector bisect a figure that it makes the original angle split into half that they are equal to each other.

This means the angle below Angle B and angle C measure is 32.5. We can find the measure of Angle B and C in triangle BOC. This is a isosceles triangle as well so

32.5 + 65 + x = 180

98.5 + x = 180

x = 81.5

Angle C is 81.5 as well so

81.5 + 81.5 = 163

Find angle o

180 - 163 = 17

Arianna has $0.70 worth of nickels and dimes. She has 4 more dimes than nickels. By
jekas [21]

Answer:

x=2 and y=6

Step-by-step explanation:

thee isn't any other way im sorry but there isn't here is a list:

1 nickel = $0.05 and 5 dimes =$0.50 = $0.55

2 nickels = $0.10 and 6 dimes = $0.60 = $0.70

3 nickels = $0.15 and 7 dimes = $0.75 = $0.85

4 nickels = $0.20 and 8 dimes = $0.80 = $1.00

5 nickels equal $0.25 and 9 dimes equals $0.90 = $1.15

so as you can see the more you add the higher the number gets and if its any lower it won't be enough sorry if you really needed that last part
