The 2nd one. The one that says CD=DA, DA=ZX, AC=YZ
There will be 354087.24 mosquitoes on the 19th of May.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division
.
Using the relation :
y = 180000(1.07)^x
x = Number of days since May 6 ;
y = Number of mosquitoes after x days
x = May 9 May 19 = 10 days
Therefore, a number of mosquitoes inhabiting the city on May 19 will be :
y = 180000(1.07)^10
y = 180000 x 1.96715136
y = 354087.24
y = 354087.24 (nearest whole number).
Therefore there will be 354087.24 mosquitoes on the 19th of May.

Answer:
14X+38+6X-18=180
20X=180-20
20X=160
X=8 , therefore :
6×8-18=30

Answer:
The minimum score needed to be accepted is 525.3.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
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:
If the state college only accepts students who score in the top 60% on the SAT, what is the minimum score needed to be accepted?
The 60th percentile, which is the value of X when Z has a pvalue of 0.6. So it is X when Z = 0.253. So
The minimum score needed to be accepted is 525.3.
